A/N: I'll be posting Male reader sibling and Gn reader sibling at some point, it'll be on yet again ealier on ao3, cuz i don't like u guys as much as my ao3 readers(jk) anyways Enjoy! i'm kinda going insane cuz my ear been hurting for days
It was a regular day, you two were watching Tajiu as he was about to confess to Yuzuriha, when a green light suddenly appeared, you saw Senku turn to stone, you should have ran, but you didn't, you tried to grab Senku, and then your senses was gone, this is all because you had 3 toast for breakfast, the unlucky number cursed you, and this was the end.
You might have gotten a little more insane while alone with your mind, a worry for Senku if you ever woke up, the cursed number 3, and pointless prayers might have scrambled the omelet that was your mind even more, so when you finally broke out the stone, your insanity went from 5 to 11, you looked to see Senku who has awaken a few minutes before you, “Senku!!!!!” You tried to hug him but he dodged “Calm down! You are naked!” he threw some vines and leaves at you to cover up “Did you count how many leaves this has?” you asked, you didn't want to put any evil numbers on your body.
“It'd be illogical to count them, just put it on, if it's an evil number just add a leaf or something!” he knew arguing with you was like arguing with a wall so he just told you a solution to your superficial problem, you started to count, as he analyzed the way the stone broke off you, 47 leafs, “47! The devil's number! We are going to DIEEEE!” he plucked a leaf off your make-shift clothes “Here 46, are you happy now?” He was seriously annoyed, “Yes.” You answered happily.
After that you followed him as he tried to make fire trying to show off to the monkeys, neither of you could do it, “It's the curse of the 47th leaf!” You were talking about this, usually you’d forgotten about such things after he gave you a solution, “It's not, we're just not strong enough for this.” he split up the tasks, he'll try making tools and such, and you go search for food and materials, but there was a problem of getting lost, you couldn't wander too far from each other, finding food was hard, he made a primitive stone tools, than a rope, and then he started a fire, hooray!
“We've been blessed by the fire!” he wasn't going to argue, you both had more than enough work, over the next few months you two worked a lot, you made some better clothes and something of a house, Senku assured you it's length wasn't an evil evil number, your clothes look like a sack of potatoes but now you can hug your brother all you want, without him yelling in disgust, “We should get on trying to find out how we broke out of stone.” He started a conversation over the barley soup water and mushroom dish you made, “Huh?” you reacted with a tilt of your head, he went on “I mean, a couple of siblings, can't really repopulate earth."
Not that he had much to go off of, just that both of them woke up around the same time, it could be a genetic thing, you two are twins after all, maybe environmental since you were close to each other, not much to go off of, it's been 6 months since you two woke up when Tajiu also woke up, he found Senku, “Well look who's finally awake, you big Oaf.” Tajiu tried hugging Senku who rejected him for being naked, you also noticed him “It's the strength blessed one!” Tajiu was crazy strong, it was good for the two of you, Senku ignored your comment as he explained how the two of you could use Tajiu for help.
With Tajiu being there and his crazy stamina you had little less worries about food, you could go back to making the weirdest ingredient soups, but Tajiu's arrival also helped Senku rule out the breaking out of stone being genetic, since Tajiu did wake up it means it wasn't connected with you two being twins at all, it was environmental. He figured out the fluid from the cave played part in it all they needed was to make some alcohol, to mix him, Tajiu found grapes, which let you make wine, then try to distill it, it took a lot of work, winter came and went, Tajku grew a beard, then shaved it using a clam, it made his face all red and puffy which was funny, and then Senku all figured out revival fluid hooray! They were planning to revive Yuzuriha, but Tajiu was worried about her nakedness.
“HOLD ON SENKU SHE'S NAKED! DON'T LOOK AT HER” was all Senku heard before Tajiu shoved his fingers in his face, Tajiu followed up with “WE HAVE TO WAIT, WE CAN'T WAKE HER UP LIKE THIS!” You went to check on Senku's eyes, worried for him, his as logical as ever ass responded to Tajiu “I know it's tough but would it kill you to try to use some logic for once, i think the stone word is kinda a special situation, there's absolutely no one around to give a damn if your butts showing, or even if your dick is hanging out.” His eyes were teary but he'll survive “YUZURIHA DOES NOT HAVE A DICK.” Tajiu sounded so offended it made you laugh a bit, as Senku argued back.
Tajiu picked up Yuzuriha to take her back to their camp, but Senku heard a noise from the tree line, and then lions came so you all had to run, “It's because there's three of us! The universe is trying to get rid of us!” you were so busy you forgot that with Tajiu it made you a trio, evil evil number, this is the universe's punishment, if you weren't in danger Senku would take the time to calm you down but the worry now was on surviving the lions. Tajiu tried sacrificing himself, but Senku told him it was stupid, then Tajiu remembered a statue of some crazy strong guy, they awakened him, he killed the lion, hooray! You were saved, and he seemed to be a cool guy, he also made you a group of 4, away from the evil evil number 3. The super strong guy introduced himself as Tsukasa Shishio, Senku introduced you two as the Ishigami twins and the Big Oaf as Tajiu. Tsukasa started hunting meat for you all, more ingredients for your soups to torture your dearest big brother which he was fine with trying them as long as it made you happy, but they weren't delightful in the tiniest bit, but what won't a boy do for family. They've started preserving food using smoking, Tsukasa broke a stone to free a statue, how noble of him, then you and Senku made soap, you are a respectable woman, you need to be clean, Tsukasa complements Senku, he thinks Tsukasa is scheming, you and Tajiu were collecting shells while Tsukasa and Senku sat back, they seemed to be talking, you were busy counting the shells, careful to make sure you got a good number so didn't pay much attention. Tajiu ran saying he got the miracle fluid, and Senku look defeated, but you don’t get why, you can bring Yuzuriha back making you a group of 5, the most perfect number there is, as Senku was making the revival fluid he said they were lacking some miracle fluid, he told Tajiu to get more but Tsukasa said he was faster and he should go, so he went. Then Senku starts making the fluid confusing you and Senku, he just says that Tsukasa is not to be trusted and he is a murderer.
He quickly woke up Yuzuriha, it took a few seconds for her to wake up, he tried to explain it to Tajiu, you got it but he didn't, then Yuzuriha woke up, hooray, now Senku told them they have 2 options split up and let them flee or stay together and fight Tsukasa, Tajiu was yelling about we stay together we gotta stop Tsukasa from killing people, when Tsukasa came back, great choice Tajiu, you were fucked, Tajiu rused at Tsukasa while Senku used a crossbow to shoot at him, he blocked it both, you knew this is going to end badly. And then Tajiu started talking about not hitting anyone and letting Tsukasa attack him until he stops killing people, it gave you second handed embarrassment, Tajiu passed out, Tsukasa left them saying something that summed up to stay away from me i’ll stay away from you, not that you trusted the words of a murder happy strongest guy in existence right now.
Senku started kicking Tajiu to get up, and he did, he also tried to hurry after Tsukasa wanting to stop him, but Senku stopped him, they wouldn’t win in a fair fight they needed technology, they smashed up the shack and left for a trip to find resources they needed to finish getting them before Tsukasa figures out to go after them, Senku used a sextant to try to figure out where they are, when Yuzuriha ran off, the 3 of them followed after her, and found a statue of buddha one made of Bronze, Yuzuriha cried at the sight, it made it so real to her. Tajiu tried saying it was inspiring but Senku kept explaining it in science, it made you laugh a little. Then Senku and you wanted the copper from Buddha, it was a valuable resource, the walk was tiring, you made a stop, you fell asleep pretty easily like a baby.
In the morning all of you went down the river with you, Senku and Yuzuriha on a makeshift raft as Tajiu pulled it. By the time it was evening again you made it to the hot springs, and Senku reviles you are making a gun, which makes you excited, a gun could make you top of the food chain, no more would you be afraid of wild animals, no more would Tsukasa be a threat. Well not really making a gun yet but gun powder, baby steps, baby steps… Senku started talking about the jump in technological advance, you didn’t care much, he mined some sulfur, that’s the stuff that’s mostly gun powder is made of, you were excited to do it. Yuzuriha and Tajiu were yapping about something while you and Senku got more sulfur, by the morning you had all you need, now all you needed to do it mix it, and pack it solid, you and Senku would never do it at home since it was dangerous, but now there was no one to say not to do it, Tajiu hit it with a big rock, and it sparkled, you 4 had to get away fast, but it means the gun powder work but also did just basically gave away your exact location if Tsukasa was close enough to be close enough to see it, and then Yuzuriha got your attention, and you saw a smoke signal, someone else is around, it’s a different direction from Tsukasa would be, Senku said to set another fire as a signal, but you weren’t sure about it, it could show your position even more… And yet you didn’t question him, you trusted Senku to make the right choice.
Tajiu and Yuzuriha ran off to get more stuff to light on fire, and then Tsukasa showed up with Yuzuriha a spear pointed at her neck, he wanted the revival fluid recipe Senku responded “Nope, sorry i guess i’m not as kind as you are, i can only look at things as being logical or illogical so i don’t care millimeter what you do with that girl, it’s not like she’s my sister and there are plenty other females to revive.” Tsukasa’s move was sudden and he cut Yuzuriha’s hair in a show of a threat “Yuzuriha!” you wanted to help her, but knew getting close to her would be a big risk, if you did Tsukasa could gain another hostage… Tajiu wasn’t in your sight, you needed him most right now, Tsukasa started talk about something, you didn’t listen you were looking for a way out, and then Yuzuriha wanted to sacrifice herself for Senku’s sake, but he, he said the revival fluid, meaning Tsukasa had no reason to keep him alive. Tsukasa and Senku were talking, their conversation was intense, you knew, you knew Senku wouldn’t give up on science ever, he’s been stubborn about science since he was a little kid… and you could do nothing as Tsukasa killed your brother, you saw Senku’s body fall, Tajiu came back and held him, your brother was dead, he was gone, your only family around, you didn’t have your father with you and now your brother wasn’t around too, the brother that always helped you calmed down, listened to all your silly and illogical rambles, fixed problems he could have left alone, your brother that always been there for you were you needed him most… You felt rage, anger, sadness, and yet there was nothing you could do to save him, he was dead and it was all Tsukasa’s fault. . . It was Tsukasa’s fault. You scream at him, for what he did to Senku, for what he did to your brother ”You monster! You killed him, YOU MURDERED HIM, YOU-” you couldn’t find the right words for your anger, it felt like the whole world collapsed, it a sense it did, Senku was the closest person to you, and now he was gone, you broke down sobbing over Senku, you wanted to yell at Tsukasa express all the rage and anger in you, but that wouldn’t fix Senku, that wouldn’t bring him back, and the sadness and grief were stronger that all the rage and anger you felt stronger then the hatred you felt in that moment… Tajiu threw the rock at Tsukasa, Yuzuriha threw the gun powder at him to which then blew up, Tajiu ran holding Senku, while Yuzuriha dragged you along holding your hand, you didn’t say anything, you felt numb and broken at the same time, none of your believes could justify what happened, not that you wanted them to, Tajiu was yelling something but it was all background noise to you, they were doing something but it didn’t matter to you, you knew the injury was deadly, not even modern medicine would help it if it was available, you didn’t feel the rain stop, you didn’t feel one thing, numbness was all you did feel. And then, you heard something, Senku’s voice, that snapped you out of it, he was alive, you and Tajiu practically jumped him to hug him, he was alive, heart beating and lungs breathing, he kicked off Tajiu, but let you hug him for a few more seconds before also throwing you off.
Senku gave Yuzuriha a mission he didn’t tell you what it would be, You two would be splitting away from Yuzuriha and Tajiu, one pair going back to danger and the other going to find the new civilization, Senku told you the fact you two had to find the other people alive, while Yuzuriha and Tajiu would act as spies, after the 4 of you split, and went your own ways Tajiu yelled his goodbye at the two of you before continuing. You and Senku found a girl pinned under a tree, she said she could wait for you two to help her, so you two started on a plan to help her, the two of you used your complained weight to pull the tree up with a help of a little rope, soap and wheels. The girl was thankful and said her name, which was Kohaku, then said she has taken quite the liking to you two, Senku answered he’s not interested, and you also said “Sorry but you’re not the type of gender i’m looking for.” to which she responded that she didn’t mean it that way she was very annoyed, not that the both of you cared, ironic isn’t it. You two tried to sleep, she wasn’t, Senku called her a lioness, she got annoyed yada yada bunch of boring talk, you wanted to sleep, annoyed by the conversation, the next morning Kohaku made a pit stop for spring water, and you all continued walking, she almost dropped it and Senku picked it up, and then immediately dropped it, which made you laugh hard as hell, “So hand it over.” you mocked him, much to his annoyance, even if seeing you laugh made him smile. Then he made a mini cart to ride down to where Kohaku leading you two, it was fun to ride, but it did crash, you and Senku landed face down, and Kohaku said that you could look at her village, it wasn’t too shabby it had houses, and people, humanity did survive after all even if just a little bit. You made it to the bridge but were threatened by the village guards Kohaku was going to fight them for your honor, how noble of her but Senku made bubbles and the guards freaked out, made you giggle, then some guy ran up to you saying his name was Chrome something about being a sorcerer, Kohaku he’s the one she was talking about, a conversation you were a part of, Senku respond “My name’s Senku that’s my sister and we’re scientist.” Chrome said how the bubbles were made, interesting, so he knows science.
He said something about fighting, bla bla you didn’t listen, and now you were moving away, that Chrome guy changed the color of fire, nothing interesting you just throw some materials into it, tho the villagers were impressed by it, well some modern people would be too to be fair, not all of them were like you and Senku, Senku said what that guy used, and that guy was pretty defeated and went to get more stuff, then he got a sulfur ball, and again said what it was and he used it better, then that Chrome guy challenged Senku to one last battle, a battle of numbers, and to no surprise of your own, Senku won. And then you and Senku saw all the materials that guy had, both of you were delighted so much! He had basically anything and everything you could want! Hooray. Senku made a gold spear for one of the guards as a bribe, and it didn’t work which sucked, you were very disappointed, not in Senku. You left the boys to their own devices in the shed and went to the stuff around the shed, you couldn’t go to the village because of the no outsiders rule which was bullshit, you walked around, looking at the grass, you mostly thought back on the past, not the recent past, but the one you’ve lost. You remembered it all like it was yesterday yet, it’s been thousand of years, you thought about going to School with Senku, all the projects you two did together, in the park, home or school, all the times he’d calm down your stupid panic, and you thought about your dad, the mornings where he made you breakfast when you two were younger or that he’d always support you and Senku in your adventures, and even when he wasn’t there you physically he’d always support you two, you never got to say goodbye to him… and now he’s gone, he’d been in space when the petrification happened, meaning you two couldn’t go and revive him, the space station probably crashed and split him into a million pieces, even if your family was an unlucky number of 3, those two were the best family you could ask for.
It brought tears to your eyes, thinking about him, and yet you never would stop remembering him, even if it hurt, you could never forget him. Your tears fall onto the grass, sometimes crying is good for you, you don’t like crying around others, but right now no one is here to judge your tears, and you needed this, the entire time you always had something to do, no time to think about what you lost, and now you weren’t in immediate danger or focused on the surviving, you could stop in the moment, and grief what you lost, it was quiet, and quiet was what you needed right now, you’ve cried for a little bit, before wiping down your tears, civilization still needed to be rebuilt. The next morning, you find out Senku wants to make antibiotics, so you are making drugs! How fun! You’ve always wanted to make drugs, but Byakuya never allowed that, he put his foot down on that one. Though you don’t have the chemicals for it or the equipment, what are you actually gonna do for it, Senku started explaining it to everyone else. You were taking the stone route, it was long but plausible. Later during the evening Senku was explaining to Chrome the bunch of stuff, and then mentioned the north star being in the true north, and well, apparently it isn't, both of you were very disappointed in yourselves for not thinking of that. Wait how did they even know where north was, Chrome got all smug that you two didn’t know about some rock, it was a magnet much to his dismay.
In the morning you 4 start searching the river for iron sand with the help of magnets, how fun! Except your back hurts after like five seconds, Senku and Chrome weren’t working, which made Kohaku upset, then came a child, a child that started helping, how cute of her, her name was Suika, you think, might be a nickname it wasn’t clear to you, you should get back to work, Senku question the villagers about some stuff they shouldn’t know about and such, and then it was time to make iron, one tiny problem, you couldn’t melt it, even with air pumps, the furnace couldn't get hot enough to melt it, you miss the technology that made it very easy to melt iron for your and Senku’s projects, he made a new plan, get more people, and to that you needed bribes, the little girl, Suika was sent to find out what the people want to bribe them.
One long wait later, you find out that they want food, Suika had foxtail millet and Senku thought about making ramen, how yummy, you prepared the foxtail millet flour, made noodles and the soup and it was time to feast! It’s been 3700 years since you had a good bowl of ramen, Kohaku, Suika and Chrome were losing their minds over it, you and Senku took a bite, and then spit it out, it was shit, not a good bowl of ramen at all, it was sandy and had a bitter after taste, like something your dad would give you when you were sick, how yucky! Tho the non modern people were losing their minds over it, so it’d probably do.
Senku wheeled the cart of ramen to the village, and let them have a bowl for a price, a price of labor, that they’d have to pay in the near future, all was going well until you heard something, something that didn’t belong in the stone world, “This ramen is making me wickedly thirsty, a cole would be great.” that's a modern person, it has to be! Kohaku got the guards, to surround the guy, the guy denies being a part of Tsukasa’s empire, of course referring to him just as long hair man just like Kohaku said it, you looked at him, holy crap it was the famous magician, Gen Asagiri, you had the guys book, you liked magic and tricks, you found it fun while Senku thought it was a bunch of crap, when you two were younger you knew a single card trick and you would do it over and over on him, making him seethe with rage as he couldn’t figure out how it work, eventually he did and it stopped being fun, but you’d never forget how angry he’d get every time you did it, it was one of the only things that ever made him angry.
The magician was pretending to be scared, but Senku didn’t care, he ate so he does labor. After the iron melted you poured it into a mold and made an iron block, Gen was weighing the options of the two sides, when Senku said you are making a generator. How fun! You couldn’t wait to do it, much to Gen's surprised face, you followed Senku into the shed, he was holding some native copper, perfect, you could make cables from it- oh he was mumbling about it, well great minds think alike, you were all happy to go do it anyway, all you needed was lighting and it came, except you and Senku weren't ready for it at all, you had to rush it, Senku made the copper wire and wrapped it around the metal rod after he had covered it in lacquer, then 3 villagers started coming down the bridge and Gen went to distract them, which they left that was over quickly, you 6 rushed to the top of the mountain, to try to get lighting to strike the metal rod, when Kohaku got a spear from one of the guards that followed you here and lighting struck the rod, the magnet was done, Hooray!
Next step was step was making the generator, Senku was puffy as hell unlike you he had the unfortunate gene of being allergic to lacquer and it was showing, you were laughing your ass off at his face, but after it as all done the beautiful generator was done, how amazing, now all you need was the muscles to run it, which was covered by gen and convincing the village guards Kinro and Ginro to do it, and then Senku made light, after so long he brought back one of humanities most important inventions, it reminded you of how you and Senku first learned about all that stuff, Senku was always interested in science and you got dragged along with him, he’d go to libraries and get books he’d read them in class too, usually talking about them to you, you’ve learnt everything because you were always there to listen to him about it.
The six of you were discussing Tsukasa and Gen, and how you need him to make a fake report, Chrome yelled to Gen, Gen responded with his usual Geness, then you saw Gen after he was jumped, it looked bad, but it was just fake blood, Gen was still hurt, and you needed to help him, Suika went out to find out who did it, after that Senku made a paste and you, Kohaku and Chrome applied it all over Gen. When Suika returned you learnt it was Magma who did it which tracks, but why now? And Kohaku answered, Grand Bout, apparently there was competition on who would marry the priestess, last time apparently Kohaku stopped Magma from winning, so it was going to happen again soon, you needed an alley to win it, so Kohaku asked if Ginro or Kinro would want to marry her, Ginro started talking about how she looked which made you want to hit him, talking about a woman like that, Kinro got to the point asking Senku what they wanted.
And like that the 2 of them started training with Kohaku, Chrome was a bit upset, and you get it, he loved Ruri but to save her, he had to let someone else marry her, the tragic story of love that may never be, reminded you of Romeo and Juliet, just with a little less dying, and poisoning, and then Senku started teasing him about it, but Chrome admitted he was okay it as long as you all can cure Ruri so she can live a long life, a love that may never be how sad and pure! It’s been a bit and yet Gen hasn't been getting much better, which was worrisome, something to look into during the morning, but in the morning Gen was gone, he ran off and caused a ruckus, which like wow men, that's how they get.
Kohaku was busy training Kinro and Ginro, after that You, Senku, Chrome, Kohaku and Suika went to quartz sand for glass. The first glass item Senku made was glasses for Suika, how cute! You chose to ignore his motive, but now it was time to make lab stuff, how fun would it be to try glass making! The answer was not at all, it was borderline torture, everything you made was shit, it was all just bloobs of glass, when Chrome had an idea, you and Senku were waiting outside the village when Chrome came back with a fossil of a man, he called Kaseki, but you heard best people in the field are always the ones 5 days away from kicking the bucket, so you ignored the mean comments in your mind to see how’ll it go, you brought him back to the science kingdom base, when he saw the glass bloobs he was interested in what were you doing immediately, Senku and Chrome put on a show for him of how bad they were at glass making the old man enraged, and he broke out the rope and crafted the class he needed, it cooled a long timed and after if finished, the lab was looking way better, reminded you of all the equipment you father bought you as kids.
The first thing he decided to make was a silver spear for Ginro, once he made it, you find out why in a bit, you, Chrome, Senku, Kohaku and Ginro to the hot springs and then past it, where you saw a lake of sulfuric acid, it was located in a low area, meaning the gasses gathered at the base of it, getting close was impossible, it was a deadly trap with an ingredient you need, high risk high reward, you needed gas masks, once Senku made one gas mask, an argument between you and Senku broke out, “You’re not going.“ he said, “I’m not going to let you go alone, that’s unlucky! What if something bad happens to you?!” you argued, “If something happens to me, you’ll be needed to rebuild civilization, if we both go and die, all of humanity's past knowledge will be gone.” he argued back, “Well then i should go! you’re smarter, you’re more important!” you raised your voice at him “I’m smarter that’s why i should go, i have a lower risk of failure. And if i fail then you’ll be needed to continue what i started.” he was trying to make logical arguments, but most importantly he didn’t want you to get hurt, “Well then lets pass the knowledge onto Chrome and go together!” You argued yet again this time bringing Chrome into it to which Senku ended up agreeing to, he knew he wasn’t going to make you change your mind and it’s better to go with you then have you go alone out of stubbornness, Chrome joined the argument arguing he’s not gonna replace you or Senku.
In the end you, Senku and Chrome went all together, it was going well, until Chrome fell, You were too far away to even try running to help, and Senku he wouldn’t make it in time, you should have insisted more that Chrome stay behind, that’ll the two of you will be enough, you thought it was over or him, you didn’t see a way to save him, that’s when Ginro showed up and saved him with a little help of Senku, and after that you got the sulfuric acid, you basically had all you needed, you and Senku got to work as soon as the 4 of you made it back to the shed, it was a long crafting process, once you were mostly done all there was left was getting alcohol, and apparently winning the Grand Bout gave you alcohol, the biggest threat was a strong guy named Magma, not stronger then Kohaku but it’d be best he gets eliminated early before he has the chance to reach Kinro who was the main hope for you all, besdies Kohaku, Ginro, Kinro, and Chrome you and Senku joined the competition too, there was no rule against outsiders joining meaning you and Senku finally go to go inside the village for the first time, and the more people in the game the bigger chance of winning.
As it started, it didn’t go well, Kinro went against Magma first, and lost due the fact he went to ask about the rules after he got Suika’s glasses melon head and Magma took a cheap shot at him, Kohaku been distracted and didn’t make it in time to defeat Magma, meaning she was out the game and no one else was a fighter that’d stand a chance against him, you thought it was done, no way of winning, Chrome was getting his ass beaten by Magma, when he tried setting fire to Magma, but Magma would have to be still for it to work, it didn’t look good until Gen showed up out of nowhere and pulled a generational clutch, saying Magma’s heart would explode, and Magma was set on fire, you, Senku and Ginro were still in a match, basically a guaranteed win, Ginro went crazy and tried to win it, Senku stopped him, with a nut cracker of a move, then you went against a guy, won using the dirty strategy of go for their nuts.
When it was Senku’s turn against Chrome, he said he was gonna throw the fight for him but Chrome has passed out, meaning Senku automatically won, the guy you were supposed to fight next yielded knowing the strategy of go for the nuts would work against him, which left you in an awkward situation of, you and Senku being the finalists, while it’d be preferred Chrome got to marry Ruri, you and Senku were facing off instead, and Senku was the first to yield before you could, so now you’ve won, and apparently married Ruri, not before calling Senku a bastard, Senku asked for the booze from your win, when you tried to leave, you were stopped for well the celebration of this marriage, you looked to Senku like what the hell and he gave you a word of advice “Get divorced.” and you did, much to every villagers shock, and then you went with the science kingdom to finish making the medicine.
And by the next day, you’ve made the anti-biotics, all there was left was giving them to Ruri, you got the medicine to Ruri, Senku dissected a rat, and confirmed it was bacterial, all that was left was to hope it’s not tuberculosis, Suika called you all because something was going on with Ruri, and by her symptoms it seemed like pneumonia, meaning the antibiotics would work to cure it, she recovered, and Senku was pronounced as the village chief, which felt rude to you as you also helped to make the medicine and it was supposed to be your role after marrying Ruri for 3 and half a minute but whatever, but what surprised you was the name, Ishigami village, as in you and Senku Ishigami.
It explained a lot, you thought Byakuya, was turned to stone like every other person, but since he wasn’t on earth that didn’t happen to him, he must have landed on earth at some point with the other survivors and reproduce making all the people present in the village, there’s 101 tales, the last two being very special, one for you and one for your brother, even in death he had made sure to leave information for the two of you to find, even if he used an unlucky number to do it. But during the celebration of Senku becoming chief, Gen came back, he warned about the fact that Tsukasa plans to attack the village, and warned about a masked warrior that was as strong as Tsukasa his name Hyoga, and with your luck it happened tonight, Hyoga showed up and injured Kinro, Ginro was supposed to cut the rope to make the enemy fall but he can’t since his brother is still there, Kinro got stabbed, Senku uses a bluff, he pretended to have a gun, it feels helpless to be unable to do anything…
The attackers retreated as the bluff worked, later while treating Kinro Senku talked about how they will attack during a storm so you’ll have to make stuff before that, they made glasses for Kinro, and new ones for Sukia too, you worked hard along side Senku there was no way to know when a storm came could be in a week could be a day. A storm came in 3 days, it felt like a bad omen to you, 3 is an unlucky number and you were stressing about something going wrong. Senku stood on the bridge, he made a show of trying to light the ‘gun’ and then the Villagers jumped the 3 attackers with katanas you and Senku managed to make in the short time, the attackers had an unlucky number so they obviously lost, but than Hyoga came, he attacked, he disarmed Magma, but he took Ginro’s spear, Magma rushed at Hyoga while Kohaku tried to attack him from above, you gasped sure Kohaku was done for, and yet… she didn’t get hurt, the spear broke apart, Gen had made a cut into it while with the enemy team, god thank god for that bastard.
But then something caught your eye, fire, 3 days an unlucky number, it seems your gut was right, something went wrong. Hyoga started talking how it was all a distraction, as everyone else noticed the fire too, a girl came on the bridge, he used gymnastic to avoid everyone, before getting away with the other attackers, you started helping evacuating everyone to the science shed, where the girl set another fire as you worked to put it out, you saw Kohaku and Senku leave, there was no time to ask them as to what happened. When they came back you learned Sukia tried to sacrifice herself to bring the bad guys to the sulfur gas path, you and others scolded her fiercely, you were glad she was okay but you also wanted her to know to NEVER do something like that again.
But new problem, Tsukasa would learn Senku is alive, you and Senku were almost of matching intellect but while Tsukasa was around Senku was always the one taking charge so he assumed you weren’t as smart, making him have no need to look for you, but now that he knew Senku was alive he’d definitely come looking, so what was the best course of action? Attack him first! Senku wants to make a phone, it’s a little insane but also you are excited to make a phone, well it’d be a very basic phone but it’d be doable, all you needed was resources and labour.
You needed to finish this before spring. It started with a cotton candy machine, so you could later use it for gold cables. It worked well for cotton candy but there was a small problem of lumps forming, which in cotton candy weren’t a big deal for it but for a cable? It’d be useless, the issue was that when the pulling rope got twisted it lost momentum and bla bla, solution making a gear, then the problem was solved, hooray.
But Senku gave you a task to twist the gold threat into a cable, a very very long cable, this isn’t going to be fun… in all that time you worked, Chrome and Kaseki made something, a Water wheel, which is amazing more power for ya, honestly you kinda felt like you were doing nothing, your brother was constantly making a project, Chrome was reinventing stuff and Kaseki was doing stuff, meanwhile all you did was follow Senku’s footsteps, you had no time to think about it as Senku said you needed to make containers for the power, needing to make batteries, Senku, Chrome, and Kaseki made those, than they made a blowing furnace, helped prepare for the winter, and now they are making lightbulbs, all that while you did nothing, honestly you felt more like a burden, what did you actually do? Contribute to the fact that the craft team was a luck number with you? The only real reason Senku kept you around is because you were his sister, sure you were smart, but never as smart as him…
You didn’t want to watch them craft, so you just kinda walked off into the forest, a nice walk would be beneficial for your mind… the forest wasn’t full of wild dangerous animals near the village so you felt safe going alone, you walked and walked, 445 steps, 446 steps, 447 448 steps, you cannot go an unlucky distance away, when was the last time you did something only you could do? Marrying Ruri, you're sure Senku would have managed on his own, you had achieved nothing, you were basically on the side lines, and worst of all you’ve only thrown tantrums about unlucky numbers, you couldn’t even protect him when he died, you felt angry and sad at how useless you were…
You don’t know when you stopped counting your steps, and how far you went, you just thought how it wasn’t fair you could have done all Senku did, if he didn’t do it first, you are as smart as he is, it’s not fair, you were lost in your thoughts of anger and sadness, until a voice snapped you out “Stop right there.” You looked up, you saw a girl your age, it was the girl that burned down the village, she was named Homura if you remembered correctly “I’m sorry, i wasn’t trying-” wait why were you apologizing to the enemy “I was just walking, what is your problem.” you changed your mind, why be nice to her when she burned down the village, “Now that’s quite rude.” she said “Burning down the village was quite fucking rude.” you didn’t have anywhere else to show your emotions so now you were just lashing out, she raised an eyebrow at your behavior, it was kinda erratic, you were breathing uneveningly.
“You don’t own the damn forest, you’re the one stalking us, so maybe be better at fucking hiding.” you just wanted a punching back to take your feelings on, but it didn’t feel that great to be mean “...” Homura still started with that raised eyebrow expression, “Stop being silent, do you think I'm below you!” you don’t know her at all but you were lashing out your feelings anyway, she stayed silent, “Say something, do you think you are too good to speak!” you step closer, she stepped back, your body language was quite aggressive, “I don’t think anything like that.” she finally says, you stare for a few seconds, realizing how insane you sound and probably look right now, should you apologise? Yes, will you? maybe, “Whatever.” you said bitterly, you looked at her, again, she was quite pretty… it made you actually feel bad for how you talked to her… so you ended up apologising, “I’m sorry, I was angry at someone else…” she just nodded before you started walking away.
“You can always join our side, it looks like you’re angry at your brother, does it make you angry that you can’t do anything? If you join us you could do everything." Those words stopped you for a second, it was a promise of being praised like Senku, being useful but that meant betraying your brother, joining a man who killed him and killing innocent people.. The offer sounded good in theory, you could be like Senku, do stuff to help humanity, be useful…
