If he's anything like me - BakuDeku

Colorful Soda Can

The pale, purple haired boy smacked directly into Izuku, tumbling to the ground and spilling his backpack full of belongings all over the road. Katsuki immediately lit up his palms with small explosions, ready to detonate if the boy started attacking. But he didn't, and after a moment of realization, Katsuki quickly knelt down and helped pick everything up.

"I'm super sorry," Izuku mumbled, helping as best as he could. "I should've moved out of the way–"

"You didn't even see me," the purple-haired boy snapped. "Don't apologize. It was my fault. I wasn't watching where I was going."

Katsuki handed the boy his bag, his eyes lingering on the giant blue-ish black mark on his pale neck. Even with the silver moon as their only light, the mark was still disturbingly dominant against the boy's twiggy body. "What're you running from, anyways?" Katsuki asked. "You okay?"

"I'm fine," the boy answered harshly, completely ignoring the first question. He took his bag and stuffed his belongings down, hoping that they wouldn't fall out again as he started running. He didn't expect to run into two kids his age, strolling along in this impoverished town after midnight. But it was whatever, not his problem, didn't matter, didn't affect him. He just needed to keep moving and find somewhere safe to spend the night.

What did affect him was the next person he bumped into: the underground hero, Eraserhead.

"Holy shit," the boy blurted, his eyes scanning the tall dark figure before him. "No... no way..."

Aizawa gently put his hands on the boy's shoulders. "Relax, will you? I'm not gonna hurt you, so no need to panic. I'm–"

"Eraserhead," the boy blurted, absolutely in awe.

Katsuki chuckled, tugging Izuku along. "I'm guessing he's a fan of yours, sensei?" he teased.

Aizawa ignored them. "What's your name, kid?"

"Shinsou Hitoshi," the boy stammered. "What... um, what are you doing here?"

Aizawa nodded to Izuku and Katsuki. "Babysitting, apparently," he told Shinsou. "But it's getting late, and it's best if we head back. We didn't make any progress today. Maybe tomorrow. Do you have anywhere to go, Shinsou?"

"Yeah," the boy lied.

Aizawa raised an eyebrow. "Are you lying to me, kid?"

Shinsou shifted on his feet, awkwardly. "Sorry, sir. Um, no, I don't have... anywhere to go..."

"That's fine," Aizawa said, a bit too casually. "You can come home with me, if you'd like. I called my husband a few minutes ago, so he should be here any second. As for the two of you–" He scowled at Izuku and Katsuki, who were mumbling and whispering among themselves. Of course, they immediately fell silent. "–the two of you better get home immediately. I don't want to get any calls from bitchy parents, understood?"

Izuku and Katsuki nodded quickly. Aizawa pulled a small piece of paper from his pocket and handed it to Katsuki. "It's my number, in case you get into any trouble. Don't be stupid, kids."

"We won't," Izuku beamed.

"Speak for yourself," Katsuki chuckled. "Thanks, Eraserhead."

"You two know how to get outta here?" Aizawa asked. "Mic should be here soon, and he can give you a ride."

"Nah, it's fine," Katsuki said. "Izuku's stepdad Toshinori is picking us up."

Izuku cringed. "He's not my stepdad."

"Well, he's dating your mom."

"Stop, Katsuki. That's so weird."

"But it's true."

"I'm going to vomit."

"Do you think they–"

"That's enough," Aizawa blurted. "Toshinori is my secretary. I don't want to hear the disgusting details of his love life."

"This is the end of my life," Izuku whispered.

Katsuki playfully smacked the freckled boy's back, a wide smile painted over his face. "Aw, don't be like that, man! Dontcha think it's kinda cool?"

"Absolutely not."

"Bummer," Katsuki laughed. "Whatever. We're off, Eraserhead. Nice meeting you, Shinsou."

Shinsou didn't answer. He watched silently as Izuku and Katsuki headed off, in the direction they came from. In the direction of Shinsou's batshit crazy father.

"So, about this goofy quirk of yours," Katsuki said a few minutes into walking back. He and Izuku were shoulder to shoulder, kicking the same soda can along with them. It scraped uncomfortably against the cracked concrete, but Izuku punted it anyway because he wanted the soda can to join them on their journey out of the rundown town. It was an absentminded wish, he thought. This silly little colorful can. Izuku kicked it.

"Yeah, what about it?" Izuku asked.

"You got it from Toshinori," Katsuki said. "What does it do?"

Izuku grimaced. "I got it from All Might, not my mom's weird bony boyfriend."

Katsuki laughed. "Whatever, same thing."

"No way!"

"Forget it. I just wanna know what the quirk is. Can you fly?"

"Not yet."

"Not yet?"

"All Might said it's like a stockpiling quirk. One person gets it, and when they pass it on, their own quirk is passed with it. So there's like six quirks in this one quirk that I'll, like, unlock eventually."

Katsuki frowned. "So you can't do anything with it?"

"I can," Izuku muttered. "It just..."

"Sorry, I didn't catch that last part. You were mumbling."

Izuku scowled. "I said... it breaks my bones."

Katsuki's jaw dropped halfway to hell. "It breaks your bones?!"

"Only if I use too much of it," Izuku stammered. "I can get, like, three percent without it hurting. Five if I stiffen up all my muscles."

Katsuki shook his head. "That's terrible."

Izuku shrugged. "Better than being quirkless."

Silence.

Katsuki kicked the can. "Is it?"

Silence.

Izuku kicked the can. "Yeah. It is."

"...You like your new quirk? Even though it breaks your bones?"

Izuku nodded. "Wouldn't trade it for it he world. It's an honor, really."

Silence.

Katsuki kicked the can. "You wanna show me?"

"Show you?"

Katsuki nodded. "Just three percent."

"...Okay."

Silence.

Izuku focused One For All's energy flowing through his body, pushing it all down to his left foot. Burning, pulsing with green electric energy. His shoe was steaming a little bit, and Katsuki was starting to have second thoughts. But before he could do anything, Izuku kicked the can.

It went flying.

"Holy shit."

"Yeah," Izuku chuckled. "But now my foot is sore."

"Is it broken?!"

Izuku shook his head, smiling brighter than ever. "No, just sore."

Silence.

Katsuki stared at where the can used to be.

"If you like your quirk, and it makes you happy, then I don't mind fighting side by side with you. That was actually pretty cool."

Izuku's eyes shimmered under the midnight moonlight. "Really?! You think it's cool?!"

Katsuki laughed and ruffled Izuku's hair. "Yeah, you little nerd. You're pretty damn cool."
