The "Better Half" ; A Poly KiriBaku x Reader Fanfic
Enjoy the series | one two three four five
You walked into the room, flustered from Kirishima, and excited to check out your name that was all over social media. You even had your own Facebook Fan Club Group. Quickly, your mom gave you juice and sat you down, wanting to talk about everything.
She sat by your side on the 2-person-couch, scrolling through fan art, fan group stuff, video footage, and such. I was already on famous birthdays, and had fan accounts on twitter.
You had gained thousands of people who had found and leaked your social media accounts, and had gotten hundreds of dms from classmates, teammates, and family friends. Everyone wanted a piece of the action.
“My baby!! With popularity like this, UA is bound to hear about you!! Gosh, my baby is going to go off and become the World’s Greatest Superhero!! The next All Might!” Inko excitedly fangirled over you, something rare in fact.
Over the years, with all your academic and physical accomplishments, the three of you had gotten so used to Inko ignoring you to give praise to Izuku, since he got none from others while you were practically worshipped for everything you did.
Yet now, as Izuku stared at you two from the kitchen, he saw how happy Inko truly was about you. How her eyes lit up, and her smile was bright. She was practically glowing. As a mother, this was how you were supposed to act.
But with Izuku, this never happened, no matter the act his mom put on. The highest grade he got was A-‘s, and never got all-A-honor-roll like you.
He never had won a science fair like you, entered a states-level championship like you, gotten 1st place at a swim meet, or been voted Class President every year in middle school.
Izuku realized now how much his mother truly wanted to celebrate everyone of your milestones. How she wanted to be that mom with the perfect child, and shout it to the world. The only reason she didn’t was because of Izuku’s feelings.
Because Izuku didn’t do anything remotely close to you. Izuku was the reason his mother couldn’t be happy with her perfect daughter. It was because Izuku was so useless that neither of you had ever become close to one another.
When Inko was finally done, she sent you up the stairs to bed, saying to get rest for your big day of training tomorrow. “Hey mom, is-“ Izuku poked his head out to talk, only to get interrupted by Inko.
“One second sweetie. Yuno’s mom Michi is calling me. She’s one of the cool moms!” Inko smiled, quickly bringing the phone to her ear and racing out of the room. Izuku sighed sadly before turning and going upstairs to you. He walked into your room and leaned against the doorway.
“Soooo… What did you do while you were out?” Izuku asked, grinning as you continued to text on your phone. You brought it away from your face, fake-thought, and shook your head.
“Just rode around for awhile. Why?” You asked, looking up at your brother. Izuku was taken back, surprised by your secrecy. Since birth, you two had told each other almost everything, but now… “Come on, I know something happened.”
Izuku began to walk over and sit on your bed when you looked up at him angrily. “Izuku, nothing happened! Stop being such a creep!” You harshly yelled, very annoyed by him prying. You did not want to talk to Izuku about boys, especially now.
Izuku stopped, shocked and hurt by your angry words. “I… okay then. Hey, I was thinking that maybe after school we could-“ He was interrupted by you looking up from your phone again, very agitated.
“I’m sorry, my schedule is packed tomorrow. I have training with my new coach and then I’m hanging out with a friend. Can it wait?” You asked as he felt his heart shatter, the wind being knocked out of him.
“Y-Yep.” Izuku whispered as he began to walk out. “Wait, Izuku!” You yelled, jumping up and running to him in the doorway. Izuku turned, happy to get your attention. Now would be when you would either apologize or want to reschedule plans for another time.
“Did you get my homework from Math and Science?” You asked, fidgeting with a pen while you stood there. “No, I’m sorry. I was just so shaken. up and I-“ You nudged Izuku angrily.
“Baka!! You were shook up? Gosh Izuku, I ruin my favorite relationship for you and you can’t even help me out?” You slammed the door in front of him and locked it. Izuku could hear you return to your bed, plop down, and eat another Pocky stick.
Snap! Crunch.
Izuku stood there, unable to believe what had just happened. Did you just… No. You were just having a mood swing again. It was no big deal… right?
Izuku stood there, listening to you talk to your friends on the phone. You giggled, laughed, and gossiped like normal. It was as if your twin brother hadn’t even gone to the hospital that day.
Izuku began to walk downstairs, only to hear his mother on the phone as well. Nobody cared, and nobody wanted to talk to him. Izuku began to waddle back to his bedroom and open his phone.
0 new messages. 0 new notifications. Just like usual, of course. Izuku began scrolling through the News, looking at all the articles about his sister, when a different article came up.
Teen suicide rate rises to all time high of 19%
Immediately, Izuku began sobbing as he brought a pillow to his face. Izuku had always had tendencies to not want to live, but had also always been scared of death. He had nothing to protect himself with after all.
He wanted to die, but the very thought of it scared him. About to fall asleep, Izuku heard a ping on his phone. How unusual… Izuku brought it to his face, happy to see it was a text from you. ‘Need 2 talk’.
Seconds later, you walked in silently and laid on the rug at his feet. “The first time… when I was attacked, ya know? I ran into the city and got lost. I was terrified. So, since I like high places, I climbed a rusty iron ladder up over 20 stories to the roof.”
You explained, closing your eyes and reimagining the breathtaking view.
“It was the red brick office building, the one with the faded Insurance logo on the front, and the rusty ladder on the right side. Gosh, you should have been there Izu. The wind was in my hair, and I was taller than the birds. I felt so connected to it…”
You trailed off, once again getting lost in your thoughts of the view.
“An-An-Anyways, back to what I was saying!! After I got attacked, I ran all over. And then I met All Might! H-He talked to me about becoming a hero, and then tonight, he offered to train me!!” You smiled at Izuku as he gave you his best fake-grin.
“I’m going to start training with him everyday until the UA entrance exam, and then I’ll get in!!” You jumped up excitedly as Izuku finally let his smile break apart. “But… what about Mom and I?” He asked you as your grin softened.
“Well, I know I’ll miss you, but I need to learn about going on my own. We’re going to be adults very soon, and I need to separate now. Plus, it’ll only be four years, and I’ll be living at home. We won’t be strangers.” You explained, but he wasn’t convinced.
“So… you really want to go to UA?” He asked, staring you right in the eye, hoping you’d deny. Izuku hoped more than anything that you would say no, and that you wouldn’t leave him. You wouldn’t abandon him, all alone while you pursue your dreams.
“Yes Izuku, I really do. I really think it’ll be good for me. I know you don’t think it’s good but I do.” You began to protest as Izuku stood up. “It might be good for you but what about us? What about you and me?!” Izuku cried out as you turned to him.
“To hell with that! I have dreams Izuku! My dream is to go to UA and become a hero! I was always going to do that with my life!” You fought back, growing defensive. “That was my dream too!” Izuku yelled as you suddenly realized what this was about.
“It’s not my fault you’re quirkless Izu.” You murmured as Izuku began crying. “It’s not my fault either! I don’t want this Ichiko! You can’t leave! You’re all I have!” Izuku began sobbing as you became cold. “Then find something else Izuku. We’re not children anymore.”
You stormed out, slamming your bedroom door behind you. Izuku stood there, frozen with emotion. How had a simple talk gone so bad? He just needed you to know how he felt. You just wanted to talk to him about the future.
Most importantly, you twol had argued. You two never argued. It just wasn’t like you to fight, especially in such a screaming sensation like that.
Izuku’s mind kept replaying the last sentence you had told him before storming out. ‘Then find something else Izuku.’ That had obviously been you telling him to stop being so attached to you.
You had said something about not being children anymore, and now that Izuku thought about it, it all made sense. The way you and Bakugo had become romantic, the way the childhood bullying had intensified, and the way you were slowly drifting away from him.
You were growing up, while Izuku was staying in his childhood. He was still pretending like he could become a hero with his stupid future notebook, and trying to exchange secrets like kids while you went on dates with boys and were training with All Might.
Deku just felt abandoned, sad, and lonely. The people he had put his love in had left him sad and heartbroken. He shut his door and covered himself in blankets, trying to fall asleep when he got visions.
“It was the red brick office building, the one with the faded Insurance logo on the front, and the rusty ladder on the right side.” Izuku got up, frazzled and horrified. Why… Why did he remember those words specifically?
Down the road from the town square, just look for it. Oh god, Izuku had to get out and get some air. He needed to get these horrible thoughts out of his head. He quickly got up, put on his sandals, and ran out.
“I need to get some air Mom!” He yelled at her, but as he looked back to the living room, he saw her sitting at the table, talking away on the phone. Nobody will even notice… Nobody will ever care if I’m gone.
The night passed when you woke up to your alarm clock, like every other day. This day was different, in fact, today was exciting. Over 1000 notifications shown on your phone, you had your first training session with All Might, and tonight, you would get to see Kirishima. You were ecstatic to say the least.
You put on a new uniform that wasn’t coated in slime, brushed your curls, and did your light makeup of mascara, blush, and tinted chapstick. You quickly ran downstairs, bag in hand, to see your tired brother sitting on the couch.
You grabbed him and yourself a protein bar and ran out, waving to your mom. On the walk there, Izuku seemed tired and sluggish, as if he hadn’t slept well. You choose not to ask, not wanting him to grow anymore agitated after your fight the night before.
So you didn’t talk, simply walking the short 3 minute stroll to the gates of your junior high. As soon as you walked through the gates, you were bombarded with your friends, and other classmates crowding around you. In the mix of it, Izuku disappeared from your side.
The topics varied, from your best friends wanting to talk about Bakugou and your safety from the attack, to your admirers wanting to talk about how you defeated a villain, and then of course how it was to meet All Might. Behind a corner, you could see Bakugo glaring at you, watching.
You almost lost your voice throughout the day, talking up a storm with everyone who wanted to talk to you. You were a hero, popular in the media, and someone who radiated girl-power after yelling at Bakugou, the most feared student in the school.
Off in the corner of your eye, you saw Bakugo in the lunch line, ignoring his “friends” and staring off at you once again. Did he feel sorry? Did he miss you? Had he heard about everything? This had been the longest you had gone far without talking.
Lunch time was the first time you got some peace to yourself. You sat at the table with 10 of your good friends, finally able to talk about something good. Bakugo would have been there, but like usual, he was serving detention in the office.
You began eating your bento when Izuku came around the corner from a hallway. “Hey Ichiko, I’m not feeling well. I think I'm going to go home for the day.” You gave him a confused look as he smiled, as if trying to hide something.
“I’m just so tired, and shook up.” You nodded, understanding as Izuku went to leave, but turned back to you. “Just know that whatever happens isn’t your fault. I love you Ichi.” He waved and left, not giving you time to speak. Weird...
Your friends quickly joined you, and you were finally able to go back to normal conversation about teachers, boys, and of course your friend’s drama with their boyfriends or girlfriends. Life was simple, but unfortunately, lunch ended as soon as it started.
You began walking in the hall with one of your friends, going to class, when she began talking about boys. “Kano and I tried but we just didn’t work out. And then Hikaru, the one I told you about with the longer hair, told me that he has a boyfriend which just makes no sense. Like, he’s gay??”
You laughed at your friend's story as you began walking to class. “What about you? Now that Bakugo is out of the picture, who do you have your eye on?” She asked as you giggled, instantly being reminded of Kiri.
“Well, there’s this-“ Before you could say his name, Bakugo slammed the door from the detention room in front of you. “I fucking knew it! Who is it?! Who the fuck has black hair and it still just soooo attractive?!” He screamed, earning everyone’s attention.
“You like him enough to kiss him on the cheek! Huh?! Who the fuck is it?! I swear I’ll rip them to pieces!” Bakugo screamed as you looked at him, unable to comprehend how he knew about Kiri.
“How do you- You’re such a stalker! Were you following me last night?” You asked as Bakugo’s eyes widened. “Tell me who it is!” He screamed as you shook your head. “No! Stay away from me you creep!” You felt your friend put her arm around you and walk you away from him.
Bakugo sighed angrily, watching you walk away without him. With all the eyes in the hallway on him, he stormed off to his next class. You couldn’t help but feel confused. Was he jealous? Was he hurt? Why did you care so much? You missed him…
You walked through the rest of your classes, all eyes on you after being called out for having a mysterious guy friend. It felt strange and weird, yet at the same time you couldn’t wait to see Kiri tonight.
When you walked into your final class, a sense of emotion walked over you. The last day of junior high before high school… it felt so surreal and fake at the same time. You were excited for the future, but scared.
You gave flowers to your favorite teachers, hugged all your friends and classmates, and took many photos. You were just so excited and sad, it was very bittersweet to leave a place you had gone every day for 3 years.
The worst part was the memories. Here, you have become your own person. You had found your own style, your own clique of friends, and your identity. Here, you had realized that you would become a hero.
Yet again, everyday here had been spent with Katsuki by your side. Six school dances, three school festivals, 4 class field trips, and many times when you would hang out behind the school together.
Finally, the day was over, and you were able to walk out into your first second of Summer. Of course, all the thoughts of relaxation were interrupted by a friendly blonde man by the entrance.
You were walking out with your friends when one of them looked at something behind you. “Ichi… Do you know that man?” He asked as you turned to see All Might in his weak form, smiling and waving ecstatically.
You smiled, relieved, and nodded. “Yep, that’s my… uncle. Anyways, I’ll call you guys later. We have training to do.” You explained as a girl to your left smiled. “Ahh yes, you are a hero in the making according to Channel 5 News after all.”
You waved to your group before running over to All Might who leaned against the school gate. “Young Ichiko, you’re looking well after last night.” He grinned warmly as you nodded. “Yea, I’ve had a pretty… eventful day.” You smiled back as you began walking.
He explained to you how he would train you to the max in hopes of making you as powerful as possible for the entrance exam, and would even train you past that until you succeeded him. He also told you about how he was going to be a UA teacher, and would keep a close eye on you always.
You two walked to the quiet beach, and began. He made you move rocks with him standing on it, threw things at you with speed and made you stop them, and of course made you go underwater and control the oxygen to keep you from getting wet.
It was hard, eventful, and left you dramatically breathing, almost gasping for air. And yet, after, you weren’t done. He made you throw rocks into the air and sent them as far as possible. He made you manipulate the ground, and use it to make you faster.
You also began running miles on the road, All Might flying above you to shout empty commands and uplifting remarks. It was all hard, and you were so tired, but you would do anything to become a hero like him.
Finally, when it was over three hours after school, you fell to your knees, feeling your heartbeat in your eyes and like you were about to throw up. “Well, I guess we can stop here. That was a very good first day, I'm excited to see how you improve tomorrow.”
He grinned, sitting on a rock nearby. All Might stood and helped you back to your feet. “You look just pitiful. Come now, let me buy you some food.” All Might held onto your arm to keep you up as you both began to walk to a nearby café in town.
He bought you a sandwich and a smoothie, tipping the cashier a 20$ bill. Being the 1# hero in the world had its perks financially of course, and All Might was rolling in the dough.
You two walked to a park bench, and sat down happily. You had a lot of fun with All Might, and he enjoyed his time with you. He likes hearing about your life, and your crazy stories. He liked it when you talked about your friends, and your brother.
You were just talking about the one time your friend and you jumped off waterfalls in Hawaii and then had to run from a water snake when you got a text message from Izuku. Your face froze, and your heart rate accelerated.
“Young Ichiko, are you alright?” All Might asked, noticing your happy demeanor turn dark. You stared at your phone as you began shaking. “Oh god, Ichiko?! Are you hurt?” All Might asked as he turned to look at your phone screen. “Oh dear.”
“I’ll miss you.”
“Tell mom I love her.”
“Goodbye.”
Instantly, you quickly went to your tracking app that you had with Izuku and your mom, and looked at Izuku’s location. “He’s… just down the street from the town square. In the Kyoko Insurance Firm?” All Might asked, confused and worried like you. “No… he’s on the building I told him about.”
You jumped up and turned to All Might. “Can you fly?” You asked him as she shook his head. “I used up all my time for the day.” He explained as you began running into town.
“I just have to run.” You sighed and began running into town, ignoring the burning in your legs and keeping your eyes on your phone. Through the town square, deep into two alleyways, and then down the street. You could already see a small group forming at the base of the building, looking up.
You threw yourself onto the ladder and climbed as fast as possible to the top. It only took a minute before you were staring at your brother who stood on the edge. “You shouldn’t have come here Ichi. I already said goodbye.”
You began to step forward as he turned around to face you. “Izuku, don’t do this. I promise you, you don’t want to kill yourself.” You pleaded as he stared bullets. “My life is useless Ichiko. I’m not athletic. I’m not smart. I’m not powerful.”
You began crying, shaking your head as you heard All Might come up behind you. “Izuku, if you jump off this building I’ll jump too.” You threatened as he shook his head and laughed. “No you won’t. You’re not stupid. Your life is meaningful. You have a bright future Ichiko.”
The tears kept coming as you shook your head, pleading with him. “Izuku, how can I live the life we dreamed of without you?” You asked as he smiled warmly. “Live life to the fullest, and have no regrets. Live it for the both of us.” Before you could speak, Izuku leaned back off the building.
Like time was slowing down, you ran as fast as you could towards the edge of the building and reached for his hand. The look in his face showed peace as he closed his eyes. You let your arm reach for his, but we’re unable to reach.
As All Might watched this, he felt a rush in his blood as he grew to his hero-form and ran to you. Flying off the building, he was able to use his last ounce of energy to reach his hand around your waist and keep both him and you in the air.
Unfortunately for them both, it gave you a front row seat as you watched her twin brother fall to his death. You cupped your hands around your mouth, your eyes glued to his limp body that laid on the sidewalk.
Screams of horror and worry could be heard below as everyone ran to Izuku. Slowly, All Might lowered you to the sidewalk in the middle of the group. Instantly, you all were recognized. You dropped to your knees, unable to speak or move.
You lightly poked his arm, begging for a response. “I-Izu?” You gasped as blood began to fill uniform shirt. “No! Someone call an ambulance! Somebody, please!” You screamed as loud as you could, fighting against All Might who began to hold you back.
“Young Ichiko, there’s no use.” He whispered as you shook your head, trying your best to fight your way out of his grip. “No! No! He’s not dead! I need to help him, let me go!”
All Might finally twisted you around to face him and spoke to you. “He’s dead Ichiko! He’s dead, and I’m so sorry.” You began crying as you hugged him tightly. “Come now, let’s get you home. You shouldn’t have to see this.”
All Might began flying you home in his hero form, finally reaching your driveway. You could see that by then, your mother had run out, even leaving the door open on her way to the car.
With the sun setting in the background, All Might sat you on the front porch with him, and let you two sit in silence. Just as All Might was about to say something, dozens of cars pulled up to the street in front, allowing camera men and reporters to spill out.
Obviously, you should have known that the 1# hero and a media sensation in the same place would bring attention.
“Miss Midoryia, is it true that you witnessed your brother’s suicide?” One asked, not passing the curb to the house but filming you two. “All Might, how do you feel about not being able to save her brother?” Another man asked, trying to get his microphone as close to them as possible.
“I’ll get them out, do not-“ All Might was interrupted by someone rushing through the crowd. “Ichiko?! Ichiko?! Oh my god!” Kirishima pushed through the crowd and ran to you in a hurry. “Are you okay? Why are all these people here? Oh… All Might?”
When he and All Might made eye contact, All Might smiled warmly at you. “I can tell you’re in good hands. I’m going to get these reporters away from here. See you later Young Ichiko.”
He patted your head and smiled sadly before flying off. Sure enough, more than half the cars followed along. “Shh…Shh.” Kirishima wipes the tears from under your eyes lovingly.
He brought a blanket from your living room and held your hand. “I’m supposing you saw.” You whispered weakly, your voice shaking harshly as Kirishima nodded slowly. “Y-Yea. Oh Ichiko, I’m so sorry.” He wrapped his arms around you as you cuddled on the outdoor porch swing.
“You want to go inside?” Kirishima asked as you shook your head. “I can’t. It reminds me of him too much.” You explained as he sadly held you in his arms. You watched the sun set over the hills, and cuddled deeper into Kirishima.
It was until it grew dark, and you got a call from Mitsuki. Kirishima picked it up and held it to your ear. “Hey Baby. Your mom and I are going to be out for a while, but your mom ordered something pizza for the house for you to eat while we’re gone.”
Mitsuki explained as you nodded. “Okay. W-Wait, can you ask Mom if I can have a friend spend the night?” You asked as Kirishima’s eyes lit up. “She’s not here right now, but I’ll give you permission. It’s not safe for you to be alone right now sweetie.”
And with that, Mitsuki hung up. “D-Do you want to go inside?” Kirishima asked nervously with a blush, noticing you shivering. You nodded, and without even trying, Kirishima picked you up bridal style and brought you inside.
He sat you on the bar stool, and got you a glass of water from the kitchen. You smiled in a comfortable silence as small tears kept streaming down your face. “D-Do you want a tour?” You tried to smile as Kirishima leaned against the counter. “Of course.”
You got up and grabbed onto his arm as you walked around. “This is the kitchen, and living room. That small room over there is the plant room where all the sunlight is.” You showed him the smaller room with a music speaker and lots of windows.
Upstairs, you began to walk down the hallway. “Here’s my mom’s room, here’s the bathroom, here’s…” You turned to look into the All Might filled, grey room with a welcome sign on the front of the door.
Just thinking of it, you remembered just that morning when you had gone to talk to him. You had told him about your plans for UA, and he had gotten upset. He had been fearful about you two leaving each other. Did that have anything to do with him killing himself?
Seeing you were about to cry, Kirishima put his arm around your waist and pulled you close. You snapped out of it and began walking again. “This is the bathroom. You can shower whenever.” You both blushed as you got to your bedroom.
“Here’s my room.” You began to walk in, causing him to follow you. Your room was a large light painted room with a queen bed next to your huge window with a desk, a full-body mirror, and led lights. You had a big closet, and you had a lot of plants all around.
“Super cute.” Kirishima looked around your room before peering out the window. “There’s… a big tree right there.” He commented as you turned and smiled at him. “Good t know.” He played it off like it was nothing but you knew what he was talking about.
You sat on the bed together, resting your head on his shoulder. “It hurts…” You whispered, feeling the tears building up again. Everything you looked at seemed to remind you of him again and again.
“I know. And it will for a while, but it’s going to be okay. Things have a way of having a good ending, even if it’s bittersweet.” Kirishima tried his best to make you feel better, and in some way, it worked.
You grabbed a blanket and threw it over you two before laying back onto the bed. Kirishima slowly followed, embarrassed yet wanting to lay down with you. You cuddled against him with his back to the window, facing him and cuddling against him.
You two decided to turn on the tv in your room and give the airless tension with background noise. He wiped your tears, told you funny stories, and made you feel better. He was good at comforting you when you felt at your worst moment.
From the street, Katsuki stared up at the window as he sat on the street curb. He had tried to come by early when the driveway had been filled with reporters, but yet again, the black-haired douche was right there with you.
Now, he had tried to come check on you, cake in hand, when he saw you cuddling with Mr.-I-have-long-black-shiny-hair. Not only that, but in bed. At night. WITHOUT INKO THERE. Katsuki refused to be replaced for his girl by some extra.
