"I can't!"

"Why not!?"

Izuku was startled when he walked inside their apartment with mom and heard yelling. It was loud, and it was definitely his daddy and Tenko's voices. Why were they yelling? Were they upset? He'd never heard yelling like this before from either of them.

He looked up at his mommy, hands covering his ears and eyes pleading for her to make it stop.

His mommy grimaced, and stepped inside ahead of him. He followed, still covering his ears. But he could still hear their muffled voices.

She kneeled down in front of him and slowly pulled one of his hands off his ears, smiling at him reassuringly. "Dear, can you head to your room? I'm gonna talk with your dad and brother."

Izuku nodded quickly, putting the hand back on his ear and running over to the hallway. Tenko and his daddy didn't even seem to notice him run past.

He hurried into his room, but left the door cracked open so he could hear what was happening. Daddy and Tenko were still yelling.

"For the last time, Tenko! There's too many risks, too many unknown factors, too many things that could go wrong!"

"Oh, so your little secret identity is more important then your own son? Do you realize how much this is going to hurt him!? How much he'll have to face because of this!?"

"I know better then you do! I've seen plenty of discrimination first hand, don't act like you know better then I do!"

"Then why won't you fix it!? You have thousands of quirks, you can't give him one!?"

Izuku was almost ready to go hide under his covers. The yells were getting louder and angrier and they were saying things that didn't make sense, he didn't understand what was happening and he wanted it to stop. But he also couldn't make himself leave the door.

"It's more complicated then that, Tenko! You don't understand how much it would effect!"

"I understand that your a coward who cares more about not getting caught then your own family!"

"I'm trying to help this family!"

"Then help him!"

"Both of you, stop this!"

Everyone went quiet at Mommy's yell, and after a long, quiet moment, Izuku heard her sigh.

"It hasn't even been a week since he found out he was quirkless. I thought we agreed to try and help him feel better, not upset him more!"

Silence.

"You two are idiots."

Izuku was pretty sure more was said, but that's the point when he closed his door all the way and walked over to his bed, crawling up in it and burying himself under his covers.

He sat there for what felt like forever, hiding under his covers, trying to ignore the hushed voices down the hallway.

He didn't like this. He didn't like any of this. He wished everything could just go back to being normal. Nothing this week had been normal.

His parents let him stay home from school this week, since the first few days he was pretty much unwilling to do anything. Which meant that Kacchan had no idea he was quirkless until Monday. What would Kacchan think?

He had actually started to doze off a little when he heard his bedroom door open.

"Zuku?"

Izuku sat up quickly and peeled out of the covers. Tenko was standing in the doorway, looking concerned.

"Tenko?" Izuku rubbed his tired eyes.

Tenko smiled and stepped over to the bed. "Hey. Sorry, I didn't mean to wake you."

Izuku shook his head harshly. "No, I wasn't sleeping."

Tenko huffed fondly.

Izuku looked at him and curled up a little more, asking in a quiet voice. "Why were you and daddy fighting?"

"We weren't fighting," Tenko wouldn't meet his eyes. "We just um, got frustrated with each other."

"What happened?"

Tenko looked up at him, red eyes meeting green. He looked sad, but then he smiled and ruffled Izuku's green curls. "Nothing you need to worry about, green bean."

Tenko sat back and his smile fell. "I'm sorry if we scared you, though."

"Me too."

Both boys turned to look at the door, where daddy was standing and looking at them fondly. "We were being idiots."

Izuku smiled with a small giggle, making both of the others smile. Izuku looked between both of their faces and his smile slowly fell. They still looked upset. Not angry anymore, but sad. Guilty, maybe.

"Do- do you hate each other?"

Tenko huffed. "No, Zuku, we don't hate each other." He glanced back at daddy, then at Izuku again with a smile. "Everything's all good now."

Izuku sat up straighter and smiled bigger, glad things were all better.

"Come on," Dad stepped back down the hall. "Mom's getting dinner ready. She's making katsudon."

"Katsudon!?" Izuku jumped up and out of bed, sprinting down the hall towards the kitchen. Tenko followed with a laugh at his little brother's antics.

Tenko was waiting out front of Izuku's preschool Monday afternoon, leaning against the outside wall and playing a video game on his switch. Inko had gone inside, apparently needing to talk to one of the workers about something before the day let out and Izuku came out.

He was so fixated on clicking buttons and beating the level of his game that he didn't notice the front doors open and someone come outside until a body about half his size charged into his side.

He stumbled, almost dropping his game as small arms gripped him tight and refused to let go. He looked down to see Izuku green curls buried into his side.

"Zuku?" He asked, eyebrows furrowing in confusion. He set his game down on the ground and kneeled beside his green bean of a younger brother, who he quickly realized was shaking. "Hey, what's wrong? What happened?"

The boy made a squeaky noise like he was trying to speak but couldn't get anything out.

Tenko bit his lip worriedly. He rested his hand on top of the curly head. "Hey, Izuku. Look at me?"

Izuku sniffed once, making Tenko realize the water he could feel at his side, then slowly pulled his head away and look up at Tenko.

Tenko saw red.

Izuku's right eye was half closed and bruised, purple overwhelming the usual green.

"Who-." Tenko closed his eyes and took a deep breath, trying to clear the apparent anger in his voice, if the startle in Izuku's eyes said anything. "Who did this?"

"A- a boy i- in class d-did it, b-because h- he found out I w-was qu-quirkless. H-he flung a t-toy a-at me with his qu-quirk."

Tenko was gonna kill a four year old. He was literally going to kill a four year old.

He could feel his hands itching to rip his gloves off and grip the face of whatever kid hurt Izuku so hard that there would be fingerprints in the dust, and-

And he was thinking about wanting to kill someone.

He felt all the color drain from his face and into his stomach, ready to come right back up through his mouth.

He shook his head in an attempt to rid the thought and swallowed hard before focusing back on Izuku.

The boy looked worried, and also a bit nervous, which was fair. Izuku was naturally good at reading people, and Tenko undoubtedly just had a lot of different emotions flash across his face.

Izuku opened his mouth to say something, but before he could speak Tenko stood up and grabbed his arm, partially dragging him towards the door, cutting off whatever Izuku was about to say into a small squeak of surprise.

"Tenko-" Izuku started, but was cut off as Tenko practically slammed the doors open and the sound of dozens of little kids screaming and laughing and crying berated their ears.

Having been into the preschool several times before with Inko, usually after Katsuki "accidentally" hurt Izuku with his quirk, Tenko knew exactly how to get to the office sort of room where he knew Inko would be going off about what had happened.

Sure enough, the second he opened the door he was met with the sound of a woman yelling.

It was not Inko however who was yelling, but another woman with hair that was glowing red yelling at her. Next to her was a little boy about Izuku's age, sitting on a chair looking relaxed and annoyed at the whole situation.

A worker was standing behind the two woman, pipping in every once and a while and looking nervous, but trying her hardest to calm the angry woman down.

The woman was yelling at Inko, who was just standing there, taking the words with an unreadable expression. This wasn't surprising to Tenko. Inko was the most patient person he knew.

Tenko listened to what the woman was saying, and he could feel the red around his vision getting deeper with every word.

"This is a waste of time, and my time is valuable! I should not have been called here over the lame excuse that my son punched yours. My son would never punch another kid!"

Inko raised one eyebrow and gestured in Tenko and Izuku's direction. The other woman turned her angry eyes towards them, and her expression faltered at the sight of Izuku's purple eye.

She turned back to her own son with a disbelieving look and he, being closest to her, rolled his eyes and muttered something no one else heard.

Then the anger was back in the woman's eyes as she spun back towards Inko, harsher than before, and mixed with the kind of disgust Tenko hadn't seen since days that brought back bad memories. He had to suppress a flinch at the sight.

"Your son is the quirkless rat!?"

The room took on a new meaning of the words cold and hard as Inko and Tenko's anger suddenly flipped a switch. Tenko could feel Izuku curl in on himself further, and the teacher froze, seeming to read the sudden change in the room.

The woman, however, was completely oblivious to the shift as she continued yelling.

"Your kidding!? I got called in here because your thing got in my sons way and yet my kids the one in trouble!? Your son isn't even human! He shouldn't exist, he is a waste of life! Of course my kids punched him, he deserves it! He probably did something stupid and bought this on himself! Actually, no, his existence brought this on him!"

The more she screamed and yelled and pointed an accusatory finger at Izuku, the more Tenko could feel his hands itching. But it wasn't just his hands, it was his arms, his neck, his face, everything was itching.

But it wasn't itching for him to scratch it, it was itching for him to use it.

Use his quirk. It was meant for getting rid of things, right? Getting rid of things he didn't want around. He didn't want this woman around, she's the one who shouldn't exist.

So just use it. Destroy her. Fix this. Reach forward. Just touch her.

He didn't realize his hand had started reaching forward until a small hand grabbed it and carefully pulled it back down to hold on tight, hugging it. He looked down to see Izuku, staring up at him worriedly.

He hadn't explained to Izuku exactly what his quirk was, since he didn't like it much himself so he didn't talk about it much. But he had told Izuku that his hands were dangerous after the boy asked why he always wore gloves.

Izuku was smart enough to know what Tenko was thinking.

Tenko sighed and let his hand relax at his side. Though he still could feel the anger boiling, he knew he'd probably just been stopped from making a huge mistake. He didn't quite let that thought settle enough to freak him out as much as it should've, though.

And now that he was tuning back in, he realized his own anger was kind of pointless. Inko seemed to be handling the situation just fine.

While Tenko and Hisashi both had the kind of anger that erupted out like a volcano in yells and sometimes physically if the situation called for it, Inko had the kind of anger that simmered and flowed slowly like lava running down a volcano. This made it harder to tell when she was really mad, but the woman seemed to finally be getting the message as her yells wavered and silences under Inko glare.

Inko opened her mouth and Tenko, knowing from experience how this was about to go, grabbed Izuku's arm and pulled him out of the room, shutting the door firmly just as he saw the chairs start floating with Inko's telekinesis.

When the three of them finally got home an hour later, the woman and the kid having gotten off with punishments that Tenko didn't care to count, Inko told Hisashi what happened while Tenko brought Izuku upstairs to get him cleaned and put a eyepatch on his eye. Tenko had experience with black eyes from when he was little.

Tenko told Izuku to wait for him in their room and he'd gone back downstairs to what looked like a Hisashi ready to go hunt down a family and murder them. Tenko vaguely wondered if he actually would if Inko let him.

Izuku never went to that preschool again.
