“Kacchan?” Izuku turned over and noticed he was gone before jolting...

He looked at his phone and his jaw dropped at the news notifications. There was a huge disaster in Shiketsu. A group of students destroyed the school from the inside.
“The scene contained and all students involved have been arrested thanks to the brave heroes that put a stop to them!”
Izuku felt a twisted feeling in his stomach. Kacchan had to be there… but he had to be okay, right?
His last message was from Kacchan.
‘Villain attack. Gotta go. Love you.’
‘I’ll be back!’
Izuku nodded his head and waited on his couch while watching the news in horror.
He held the envelope tight to his chest before his hand instinctively reached for his stomach.
“Don’t worry…” Izuku said fondly. “When Kacchan come back, we’ll make him feel better.”
“Kacchan?” Izuku questioned before rushing to open it. It was unlike the alpha to knock that way. He flung it open and felt his heart stop when he saw the solemn, devastated looks on Todoroki, Kaminari and Kirishima’s faces.

Katsuki eyes snapped open as he woke up in a giant field of grass. He whipped his head back and forth before seeing a bunch of the kids he saved from a falling building surrounding him.
“No way…”
“This Hikaru’s quirk, isn’t it?”
“It’s gotten so much stronger…”
Hikaru? Was that the brat with the gold hair’s name?
“DynaMight’s here… this is bad!”
Suddenly Katsuki remembered what this ‘Hikaru’ told him!
And then there was golden haired kid. He was quiet and didn’t say anything. And from what Katsuki understood, didn’t do anything!
But the heroes made a terrible mistake ignoring the golden haired kid!
“Amazing job, number one! Guess you don’t need Deku at all, huh?” Hikaru said with admiration. “But the world does need you. So… what if they lost you?” He grinned.
“Huh?!” Katsuki fell endlessly in a black void as the kid’s voice echoed in his head.
“My quirk isn’t that powerful but it is useful. I’m so happy I could use it on you!”
Katsuki launched himself in the air with an explosion as he tried to rise out of there. There was no way! There was no way he wouldn’t fulfill his promised to Izuku!
Fuck…. There had to be a way out! There had to be!

Sixteen Years Later
Bakugo Yagi walked in to UA High School with a heavy heart. His classmates talked to him, smiled at him,
“Bakugo-kun! Did you see on the news what Chargebolt did?! Wasn’t that hilarious?!”
They didn’t know. No one knew. He felt screaming and breaking down but he couldn’t! Because it was all his fault.
And according to the man he looked up to as his sire, who was never allowed to call himself that, he likely wasn’t going to make it…
“I’m a villain…”
“Huh?” One of his classmates questioned.
“Nothing! What the hell did that Dunce Face do now?!”
“That’s mean!”
“He kinda does have a funny face!”
Everyone laughed and laughed. But Yagi just wanted to disappear. Why did everything go so wrong so fast?
“Midoirya… please try and fight this! Please!” He begged while squeezing his hands desperately before noticing the date on his watch.
“Please…” He kissed his hand desperately. “I can’t lose both of you on the same day!”
He hung his head low as he heard the sound of the clock ticking away.
Before Shoto could react, a strong gust of wind blew the window open. He didn’t know what it was… but after two agonizing weeks, he felt… hope.
“You can walk yourself home! You’re strong enough!” Yagi snapped.
“What’s your deal?” She puffed her cheeks skeptically. “Before we started high school,”
“Fine then! I’ll walk you home!” She persisted.
“What the hell do you want, Risa?!” He snapped.
“…Is everything okay with Uncle Deku-San?” She asked timidly. “Mom won’t tell me anything.”
Was this the call? Was his dam gone forever? Did he kill him? Was this it? Sweat dripped down his face as he checked the caller ID.
He quickly ignored it before sighing. That’s where the trouble all started.
Growing up, Yagi was a happy child. He never questioned what his mom told him and believed him whole heartedly. That he had the best sire in the world! He was just lost somewhere!
Yagi never thought of the possibility that he was a lunatic putting his life on hold for nothing.
“You must be relieved, huh? We were all worried you would turn out like your mom!”
It started with little comments like that.
Uncle Shoto and he were across the room with Uncle Iida talking about something else. Not close enough to hear what was being said.
“You’ve had too much to drink, man! Cut it out!” His uncle Kirishima had scolded.
“He’s old enough to realize it himself, Kirishima.” Kaminari sighed. “Your mom’s gone insane. He was crazy before, but…”
“You mean Uncle Shoto?” Yagi blinked in confusion.
“See? Isn’t that so messed up! Guy raises you and you can’t even call him your Dad because your mom is hoping for the impossible!”
“Yagi… you know your sire’s not coming back, right?” Sero asked him seriously, ignoring Kirishima.
“Dude!” Kirishima shoved him, noticing the crushed expression on Yagi’s face.
“SHUT UP!” Yagi screamed before storming off.
“No! I don’t know why you decided to throw a stupid party! I wanna go home!” He lashed out at him as he felt intense grief.
His whole life, he believed his mom’s fairy tale.
But of course that made no sense. If he really was out there, what would keep him away for that long?!
Uncle Kamianri was right, in all ways but biological, Uncle Shoto was his father. He raised him alongside his mom and took care of both of them!
It was cruel!
“Grandma… Grandpa…” He had visited them to understand. “Do you think my mom’s crazy?”
“What do you mean, dear?” His Grandma Mitsuki questioned.
“Is my father dead?”
“Of course not.” Mitsuki cried a tear before caressing his face lovingly. “Katsuki’s alive in you!”
“But is he alive?!” Yagi was sick of sentiment! “Tell me the truth!”
“Katsuki would be really proud of who you are…” Grandma Mitsuki smiled.
“Yagi! It wasn’t our place to-”
“Contradict mom?!” He said bitterly. He had all these bitter feelings about his dam. He felt lied to!
“Yagi! Dinner is ready!”
“How was patrol today?” Izuku asked Shoto.
“Good. No villains out. Maybe it was the rain.”
“Kacchan used to hate rain patrols but I liked them a lot!”
“How does your quirk do in the rain, father?!” Yagi asked Shoto casually.
“Um…”
“What?” Yagi questioned. “Am I not allowed to call you that?”
“Todoroki-kun is probably just shocked, Yagi!” Izuku smiled nervously. “I m-mean you have a father and-”
“I never saw him as a replacement, mom!” Yagi stood his ground. “What a cruel thing to say! Taking care of us? He loves us! We’re not his pets! We’re his family!”
“I know what you meant, Midoriya.” Shoto put his hand over Izuku’s. “Yagi… where is this coming from?” He asked in concern.
“I guess you’re cruel too, huh father? Do you not see me as a son?” He asked directly.
“What, when he’s not here?” Yagi gestured to Izuku.
“Yagi- if y-you see Todoroki that way, that’s fine! I don’t want to get in the way of the people you care about!”
“Yagi! Your father really is coming back!” Izuku insisted. “I know it’s not fair right now but when you see him, you’ll understand!”
“Shut up!” Yagi snapped.
“Don’t talk to him that way!” Shoto stood up.
“You both make me sick! I’m going to bed!”
Things were tense in the house after that night. But Yagi wasn’t going to back down. He still insisted on calling Shoto ‘father’.
“You know… maybe you’re the only one who could save your mom from himself.” Kaminari had said to him one day. “Save your real father from living in the shadow of your dead one.”
Yagi tried to reason with him a few times but he was such a stubborn person!
“Yagi, it’s okay if you’re tired of waiting. You can believe he’s gone if it makes it easier.”
It was hard to make him see the light. And now that Yagi embraced the truth, he felt his whole home covered in darkness.
Yagi was happy he got in. But he knew everything he did would be compared to his late father. And now that he accepted his death, he took the responsibility of keeping his torch burning seriously.
“One more! One more!” Izuku had excitedly taken picture after picture of him in his uniform. “Wait! I think Kacchan would like to see you with this!” He ran into his bedroom to get some sort of baseball card.
“Wait! Yagi! Please just a few more for Ka-”
“STOP IT!” Yagi’s patience ended. “HE’S DEAD, MOM! DON’T YOU GET IT?! HE’S ALWAYS BEEN DEAD!”
“Yagi!” Shoto rushed in the living room.
“He’s gone, mom… but I’m here! Uncle Shoto’s here! I’m not a kid anymore who can just believe in your delusions! You need to accept reality and stop torturing me and everyone around you! It’s exhausting!”
“You’re just as pathetic, father! If you love him, you’re wasting your time too! Mom’s dragged you around enough! Go live your life! All he’s doing is using you and you’re letting him!”
“Do you believe he’s alive?” Yagi asked Shoto seriously.
“That doesn’t matter!”
“Of course it matters! Did you see my sire die or not?!”
“You’re the reason Mom is as sick as he is!” Yagi growled.
“I’m not sick! I’m sorry I’ve hurt you, Yagi!” Izuku cried. “I’m so sorry! Maybe I should have kept my hope to myself”
“Yeah?” Yagi said coldly. “Then use your head, mom. If he is out there, he’s moved on with someone a lot more useful than a quirkless omega.”
It was villainous of him. He didn’t even know where it came from. Uncle Shoto grabbed him by the collar and dragged him outside without looking at him.
Then one rainy day, Yagi came home to a foul smell. Distress. Intense distress.
“Mom? Mom!” He rushed to his side.
“I bought a house…” Izuku said in a zombie like trance. “Is that okay, Kacchan? It’s big enough for Yagi to have company over and not be embarrassed.”
“I visited your grave yesterday… I hate what they did with it… you would have wanted a shiny gold tombstone signed by All Might himself!”
“Mom! Mom! Stay awake! Hey!” Yagi shook him as he looked sickly, like a ghost! “HELP! HELP!”
Midoriya Izuku had dropped from the grief he finally allowed himself to feel. And he did it all for him… Yagi was a killer.
“Yacchan! You look sick!” Risa snapped him out of his thoughts.
“That’s how I always feel when I’m around you! Go home!”
“You’re terrible!” She scolded. But Yagi had enough and blasted himself home with his quirk.
“Hey! You!”
“What year is it?!” Be asked desperately.
“Um… 2164?” Risa supplied.
“FUCK!” The guy screamed before taking off the same direction as Yagi.
“Um… you’re welcome weird cosplayer!” She shouted back.
“Who is it?!” He questioned.
“IZUKU?!”
Yagi quickly opened the door and was stunned to see what looked like his twin only with red eyes… no… it couldn’t be…
“DAMNIT!” The guy cursed to himself
“Is this… a sick joke?!” Yagi blinked.
Yagi wondered if he was deluding himself. If his mother’s hopes had risen to haunt him as revenge for killing him so cruelly. Maybe this was a quirk… or maybe he had fallen asleep and dreamed it.
“Aldera Omega Rehabilitation Center….” he said shakily before the stranger’s eyes widened and he took off faster than anything Yagi had ever seen leaving a trail of sparkles in his path. “No fucking way….”
The day Shoto broke the news to Midoriya of Bakugo’s death, he expected the worst.
He didn’t expect him to smile. He didn’t expect the omega to put his hand on his shoulder and comfort /him/. “It’ll be okay, Todoroki.”
“Midoriya…” Kirishima said sadly. “He’s not… we all saw-”
“You didn’t see enough! If you did, you would have brought his body back to me, right?”
“Midoriya-” Kaminari stressed. “He-”
“Has to come back and meet his child.” Izuku put his hand on his stomach.
Shoto made a decision then that he wasn’t going to let him be alone.
“I’m… sorry?” He asked Kaminari one day.
“I said I can help you with your ruts!”
It sounded logical at the time and Shoto really didn’t want to ever break and impose on Izuku.
“Really?” Izuku smiled sadly and Shoto could tell something was wrong.
“Did something happpen?”
“I just got off the phone with Kaminari-kun. He made some fair points!”
“Just that maybe I’m being unfair to you! I never want to hold you back from a happy family!”
“I guess I just worry for you when Kacchan comes back! I don’t know how he’ll feel about you living with us!”
“Midoriya, I know what I signed up for!”
Izuku nodded his head and cried into his chest gratefully that night. And Shoto stopped seeing Kaminari. He stopped seeing Hanta too for good measure. They both seemed to take it well. But maybe he was naive.
After Yagi said those awful words to Izuku, he was inconsolable.
Izuku felt like he failed him. That he caused so much pain in his child that he earned his hatred.
So Izuku did what he never allowed himself to do. He accepted Bakugo’s death. He took the time and allowed himself to finally grieve.
“Yes…”
“What were his last words? Tell me…”
“He told me to tell you he was sorry…”
Izuku sunk deeper and deeper into his own grief. Like everything he did, he pushed himself too far too fast.
“I made you put your life on hold! I gave Yagi false hope! I didn’t come to Kacchan’s funeral! I’ve never even visited his grave! How awful! I’ve been so awful!”
“Izuku…”
“Huh?”
“You can call me Izuku…” Then he kissed him. Shoto knew he was just doing what he thought Yagi wanted.
“Stop…” He gently pushed him away. “You don’t want this!”
“Oh… right…” Izuku took it as a rejection. It was the wrong thing to say at the worst time.
All Shoto meant to say was he didn’t need to be with him in that way to be happy! He knew he could never fill that void
If he just made Izuku somehow accept it before Yagi was born… if he just told Yagi the truth when he was young and could understand his mom’s need to believe it.
“LET ME THROUGH DAMNIT!”
“Bakugo?!” He ran into the hallway to the see his ‘deceased’ friend being held back by the nurses.
“It’s not Yagi-kun! It’s a stranger!” One of the nurses shouted to security.
“Bakugo… is that really you?!” Shoto rushed to them.
“Huh? Todoroki-San! It can’t be the real him, right?!”
“Half and Half?! Tell them all to back off and take me to Izuku! What the hell is he doing in a place like this?!”
‘Powerful Disgraced Former Student’s Quirk Explained!’
‘No Dynamight sightings yet!’
“LET HIM THROUGH! IT’S HIM!” Shoto demanded, shocking the nurses.
“Where is he?! What happened while I was gone?!”
“Fuck! You’re starting to look old! It really has been that long?!” Katsuki questioned in a panic.
“I should be the one asking questions!”
