After all this tobiizu shit I'm dating a big introverted almost albino guy. But he's so nice that I can't not have a heart and go all-izuna-core. For now.
You know, when I first came across this meme I thought about Hashirama. It just suits him (even if I hc him to be a terrible cook)
The back of the cookie is charred, and it makes Hashirama cry, not because it's ruined, but because Madara would have eaten it anyway if he was there (Madara can eat literal coal)
It’s 2026 and I’ve decided to start posting a Castlevania fic, haha🥲 It’s actually an older piece I never uploaded to AO3 — I just really missed trephacard, so I finally came back to it. The story is already finished; I’m posting chapters on a schedule in Ukrainian first, and then translating it into English.
Also, alexlutece (on Bluesky) made these beautiful collages featuring our trio, inspired by the Sun–Moon–Star tarot aesthetic ✨🦇🖤
basically me and @n0pepng throwing ideas at each other but compiled into a nice post to share with the class.
this whole thing is straight up crack, suspend your disbelief and enjoy the show :D
Ace attorney AU where Tobirama is a defense attorney (with spirit medium assistant Mito, who thinks watching her boss’ life is better than any soap opera humanity can come up with. She’s always there eating popcorn and being incredibly entertained).
Izuna is a prosecutor, and they are so obsessed with battling each other it makes everyone soooo uncomfortable. One day however Izuna just up and dies, saddling Tobirama with unnecessary... feelings.
He anonymously posts this online to vent:
Except Izuna is alive and well; it's all an elaborate ruse for busting open a very big corruption case that had the (un)fortunate side effect of making Tobirama realize things. Izuna could just temporarily be in witness protection and they just told everyone he died in a very big explosion idk
So one day Izuna is bored out of his fucking mind in witness protection in the middle of fucking nowhere and he's just bedrotting and doomscrolling and he comes across the post. It doesn’t really take a genius to figure out that it’s about him and the identity of its OP.
He spends all his time microanalyzing every tiny detail and interaction (bless his photographic memory). Not one to be outdone in ANYTHING, he begins orchestrating bizarre happenings and leaving cryptic messages for Tobirama, sending him on a wild goose hunt that has everyone thinking he’d become conspiracy pilled.
Then the final clue fits in place on Tobirama’s birthday and he finds the thing all the evidence is pointing him to and its just a racy photo of Izuna with "hbd u ugly fukc" written on the back. It takes him a second but he weeps with joy before he even can stop himself.
On the photo, Izuna made sure to position a newspaper dated post his alleged death riiiight between his legs to a) show Tobirama "look I'm not dead!" and b) to force him to really look
Tobirama, with a hard-on: God I fucking hate this asshole
Tobirama joins the case that put Izuna into witness protection and goes extra hard on pinning the bad guys so Izuna can come out of hiding. Once it's all over however Izuna acts like none of it happened bc seeing Tobirama losing his marbles makes him >:}
Little does Tobirama know Izuna would love to receive a proposal in the form of a riddle hunt, just like the one he gave Tobirama. Which he eventually figures out because he's smart. It was Mito. Mito figured it out and beat him over the head with it.
They get married but literally nothing changes re: how they act in court, everyone thinks "tbiz got married" is some weird baseless rumor. Tobirama invites coworkers over One (1) time and everyone is shocked to see Izuna there, watering their flowers or something cute and domestic like that.
Coworkers: he just told you he'll dismantle your case so hard they disbar you on your way out of the courtroom. That wasn’t even 5 hours ago!
Tobirama: yeah sorry i told him to tone down the pda he never listens :|
All of them fall silent bc an entire movie of the pair roasting each other to Hell and back plays in their minds and they all wonder if that was all basically foreplay
(it was)
Then once word comes out they stop letting them go against each other bc conflict of interest or whatever which leads to the tobiizu divorce arc only so they can face each other in court again
Izuna: divorcing you made me kinda horny ngl
Tobirama: … I’m free this afternoon.
They keep remarrying and divorcing bc they’re freaks like that
Izuna, screaming: I Want Another Divorce! re:the mildest inconvenience
Tobirama: sigh do we really have to do this again? It's so time consuming. I can whip you without getting a divorce
Izuna: IT'S NOT THE SAME.
Tobirama gets him coffee with 3 sugars instead of 4 and now there are divorce papers on the table. They have an entire stash of pre-filled copies. They're on a first name basis with the clerk who files the papers. They gave a speech at her wedding. Izuna invites her to go dress/suit shopping every time they get remarried. They are her child's godparents.
When they’re married they are not any better. Like at all.
Izuna: Well my 3rd husband promised to always cook for me
Tobirama: well my 5th husband promised to blow me whenever I do
Izuna: WELL MY 8TH HUSBAND–
Everyone: What is going on. How many times were they married before? What does that have to do with anything?
They only remember all this bc Izuna has a photographic memory and Tobirama has a spreadsheet kink. If any of their friends and family don't show up to the weddings they make it into a big ordeal. They show powerpoint presentations at every wedding, calling out all the people who didn't attend their last wedding.
Hashirama has never missed one. He loves them. With every invitation he's crying tears of joy like it's the first time.
Madara receiving an invite to Izuna’s 17th wedding to the same guy: 😐 fuck this I’ll just send a card.
Hashirama is also kinda maybe running a gambling ring on their divorce/marriage cycle. Tobiizu find out, Tobirama wants to reprimand him for it but Izuna thinks he should just split his earnings and in exchange they'd keep him updated. Madara busts them for insider trading. (bc they didnt let him in on it.)
Maybe the brothers are the first Uchiha to go into law instead of crime? So all their dead relatives are like hell yeah our criminal genes are NOT dead
(No one is wise to Mito’s Annual Bingo centered around their wedding(s).)
The weddings become family events. Both families go so hard on it. When they're married the respective partner is treated like one of their own, when they divorce they cheerfully bring out the scorned ex-spouse we "never" liked treatment. It's all in good fun.
Hikaku: hey Izuna just wondering if your next divorce is gonna be around the holidays bc im buying gifts and i need to know if Tobirama will still be my BIL by then
At the next wedding, there is an entire slideshow just blasting Madara alone. The crowd boos and Madara swears he’s never attending again.
Speaking of, time to move on to the big brothers for a little. Madara is a detective, one of those broody guys who sit alone in a pub after his shift ends, lamenting the evils of humanity…
but one of us has to do the right thing....... And it's me.
Hashirama is the bartender & that's how they originally meet, before tobiizu even graduate law school. He keeps giving Madara beer for free; Madara tells him he's trying to quit smoking and Hashirama is like i’ll give u a free beer for every pack you dont smoke! which like... good intentions, horrible execution
At the same time Hashirama is like: wow but he's so hot when he's smoking… :(
Hashirama also lives above the bar and so he tries to get Madara wasted on purpose.... So he can be the savior and have him crash at his place…
Madara ofc quickly figures it out. He confronts him one day and watches him stutter and fumble for 15 whole minutes only to admit his "horrible shameful ulterior motives": He wanted to tuck Madara in and make him breakfast bc he looks like he doesn't sleep or eat well.
Hashirama: otherwise you wouldn't ever eat anything healthy TToTT
Madara is like "..." and spends the night over. Hashi wakes up at 5 am to get the freshest ingredients and spends all morning fussing panicking upset about fucking up the eggrolls (they were fine) and how he’s so sorry for feeding Madara such terrible food.
Madara: my breakfast is cigarettes and stale coffee anything you feed me is an upgrade you moron (affectionate)
Hashirama: well... Perhaps... If you'd let me... I mean.... Maybe I could....... I mean........ If you want........................... DINNER?!???!?!!?
Madara: …………….Steak. Medium rare. Don't fuck it up. I finish work at 8.
Hashirama: booking the best 5-star chef to teach him as they speak
But then he would stress about it so much he does fuck it up and when he picks Madara up, he's in tears bc he thinks this was his only chance
Madara: He's so stupid.... i have to have him.
Later on Hashirama would make him bento boxes and drop them off at the station. Everyone starts speculating what kinda tradwife Madara bagged. Until they spot Mr. 2m tall broad and buff and handsome and goofy with the world’s most charming laugh, and it turns to literally no one understanding why Hashirama is with him.
Chief is so grumpy and broody and hell to be around... how is he in such a wholesome relationship....
But then they start stalking them a bit. And watch Madara suddenly be a gentleman, they discover a whole other side of him and it's kinda scary. Holding doors open for Hashirama, sharing the bento, feeding him, sending him reminders for important appointments and stuff bc Hashirama tends to forget, telling the restaurant ppl he asked for no pickles. When they still put pickles, he fights them on Hashirama's behalf. Hashirama talks and Madara sits there like
the cadets discover their chief is capable of smiling. Miracles were real. Madara dislikes that, so he tries to be extra grumpy. But then he has to take over some big case and barely gets any time for himself, let alone for Hashirama
So at one point they organise a candle light dinner at the station for them, and just lock Madara inside so that he has an excuse for why he can't leave and do his work, and from then on he's a tiiiny bit nicer to them. For their birthdays he gets them cards that say "I tolerate you", "you are an ok officer" and "your presence does not make me want to shoot myself", and the fan favorite: "you're not fired (yet)"
They frame the cards.
Things get really funny/weird with tobiizu in the mix tho..
Tobirama comes to ask for evidence one day and Madara makes his life hell.
Madara: this is for that PowerPoint presentation you little shit i know it was your work Izuna would never use times new roman in a slideshow.
Tobirama: but do you really think those cliparts were my work?
Madara: focus on your own predicament, brother in law. Don't worry about Izuna. He's getting his own comeuppance.
Tobirama: oh yeah? Be careful tho... I know your weak point...... It's Hashirama. And nothing would hurt him more than me saying I'm on a meat-only diet now.
Madara, horrified: You'd hurt your own brother just to get me?! Izuna was right. You really are an unethical mercenary of a lawyer!
All the other cops around them: w-what is going on. Should we call for help
Tobirama, smashing his fist on the table: IZUNA SAID THAT? fuck that's hot. already planning to remarry him
Madara books him for destroying police property
Izuna comes to bail him out but ultimately doesn't bc he thinks it's hot to see him behind bars. (also they’re divorced currently, he can stand to suffer a little)
They both make a point of needling him till he loses his patience.
In the background, Mito is making a phone call to the only person who can stop this mess and Hashirama has to come to calm them all down. He retains his canon "Hashirama The God of Shinobi" glare, but like... rarely ever uses it, this is one of these rare instances.
Everyone stands in front of him looking at the ground in shame
Hashirama: Madara, he didn't even break the desk. Don't be so mean!! Izuna, stop taking photos of Tobirama behind bars, i don't think that's even allowed here! Mito, you should have called me much earlier!! Tobirama......... What do you mean meat-only
:((((((((((((((((
They all walk out of the precinct like scolded children. Except for Tobirama, who walks out with a fruit basket, and Hashirama will be expecting daily updates about his fruit consumption or he's gonna escalate his intervention
At one point Izuna gets really pushy with Madara about attending the next Wedding. Unbeknownst to him, it's his wedding to Hashirama, which he only learns when he shows up. He spends the rest of it bragging about how it'll be his first and last wedding unlike some people–
Meanwhile Izuna and Hashirama have already come up with another business plan that Madara will not like...
Mito: Madara, I have spoken to your ancestors and they want me to tell you......To stop being such a fucking killjoy. Just divorce Hashirama, get the bag, and then you can remarry next year
Madara: It's about the principle woman! Also My ancestors were all criminals! I'm not taking their advice!
Fun extras:
Mito is friends with both the Uchiha brothers (Madara doesn't know he's her friend tho)
She has a forensic psychology degree, though she returned to Uzushio to complete her spirit training and didn't want to give up on her now dying culture. Her work with Tobirama lets her dabble in both sides of herself and she loves it.
Hashirama has a mysterious past from before he was a bartender that he never speaks about. Some of his skillset is not things your typical bartender would know. whenever he's asked about it he just says he "retired early"
Tobirama has cross-examined a Parrot. Izuna responded by calling a bunch of cats as witnesses.
i really love the theory that madara and hashirama were the ultimate case of unrequited love. like, if you actually look at the canon, it’s not even a rivalry, it’s just one man making another his entire universe while the other person had a whole world to care about. let’s talk about it
I. childhood: awakening the sharingan
everyone knows that for madara, growing up in an era of constant death, hashirama became the first and only bright spot (except for izuna, obviously)
canonically, the sharingan awakens from intense emotional trauma. madara awakens his when his friendship with hashirama — the only person who understood him from their very first meeting — is officially declared impossible because of their last names
this is the first moment of his "broken heart." madara trusted hashirama with his vulnerability, and from that moment on, his psyche was locked onto this man
ll. the founding of konoha: the attempt to be number one
despite the massive pain of losing his brother, madara gave himself a chance to live "normally" and trust hashirama to fulfill their shared childhood dream
when konoha was built, madara hoped that he and hashirama would rule side by side, just as they had dreamed as kids. madara only recognized hashirama; after izuna's death, he became the only person close to him, his only priority. but hashirama still had tobirama and the entire village
when hashirama became hokage and started listening to tobirama and the villagers, madara realized he was just "one of many" in hashirama’s heart. hashirama loved the village more than his friend, and that was the beginning of the end
lll. leaving and loneliness: the life of a ghost obsessed with the past
madara gave up on having a personal life. while hashirama starts a family with mito, madara chooses to stay alone. he has no wife, no followers. all his connections are purely functional (like with obito later). he literally "preserved" himself in his feelings for hashirama because he realized he would never feel anything like that for anyone else again
when madara decides to leave konoha, a crucial dialogue happens. as he’s leaving, he tells hashirama directly: “only you can stop me.” this isn't just a threat. it’s a confession of deep intimacy. madara is literally saying: “neither the uchiha clan, nor the village, nor the whole world means anything to me. you are the only one whose opinion and whose power have any influence over me.”
his entire life in the cave was just studying hashirama's cells and having a never-ending internal dialogue with him. for him, there was no world where hashirama wasn't the center of the system
lV. the fourth shinobi world war: the peak of obsession
madara humiliates the five kage, saying they are nothing compared to hashirama (poor tsunade...). he literally "advertises" hashirama, basically saying, “listen, look how great he is, only he is worthy of me.”
decades after his death, madara acts like a man who came to a date, not a war
until hashirama showed up, madara fought the shinobi alliance with the face of someone doing boring homework. but as soon as he felt that chakra, he literally bloomed. his line “i've been waiting for you, hashirama!”is the peak of his multi-year fixation on one person
while stabbing sasuke with a sword, madara repeats from memory the exact words hashirama said to him before his "death": “i won't forgive anyone who threatens the village, be they a friend, sibling or even my own child” this confirms madara’s obsession — he literally kept hashirama’s words in his head for decades!
V. the infinite tsukuyomi: an attempt to prove a point or "notice me, hashirama!"
madara wanted to create a world without pain and sacrifice, where no one would have to feel what he felt. but on a deep psychological level, it was an attempt to prove to hashirama: “your village failed, my way is better.” it was a cry from a man who wanted the only person who mattered to finally admit he was right
when madara finds out he was deceived, his world crumbles. but he doesn't waste his last breaths cursing zetsu or kaguya. his final thoughts and words are addressed to hashirama. in anime he asks: "hashirama, where did i go wrong?" it’s not a question to fate; it’s a question to the only person whose approval he ever needed. even as he dies, he continues this dialogue that started at the river decades ago
as he dies, madara feels hashirama’s presence — the only person in the world who matters to him. madara admits defeat. he looks calm but deeply sad. he talks about his dreams "crumbing." hashirama calls him "comrade." until the very end, hashirama saw him as a "partner in a dream." madara, however, saw hashirama as the only reason that dream even made sense
the tragedy of madara is that he is an uchiha. for this clan, love is obsession, madness, and sacrifice. his biology forced him to feel an intensity of feelings for hashirama that the latter physically could not feel in return. for hashirama, it was a strong friendship, but for madara, it was an obsession
madara was ready to burn the world for hashirama
hashirama was able to stab madara in the back with a sword for the sake of peace
madara would never have done it first. he always chose hashirama. hashirama always chose the idea
madara uchiha is the greatest example of how you can be the strongest person in the world but remain absolutely powerless before someone who is just a "good guy."
of course, hashirama loved madara, but he loved him the same way he loved tobirama, konoha, and the world
the tragedy of madara is that he wanted to be exceptional to hashirama, but became only a part of his great legacy
