Izuku is tired of playing the innocent cinnamon roll everyone thinks he is. Bakugou is tired of watching his best friend pretend. Todoroki is tired of acting like he doesn’t know Dabi is his brother. Iida is tired of being the “responsible one.” On a peaceful Sunday afternoon, four students decide it’s time to drop the act—and maybe invite some villains over for a chat
In this AU, Izuku and Tenko are brothers. Things are about to get interesting.)
Chapter 1: Dropping the Mask
The sun hung lazily in the clear blue sky outside the U.A. dorms, casting warm golden light across the common room. No villain attacks. No emergency drills. No crisis demanding immediate hero intervention. Just… peace.
And Izuku Midoriya was bored out of his goddamn mind.
He sprawled across the common room couch with all the grace of a ragdoll, one leg thrown over the armrest, his phone dangling from his fingers. The innocent, bright-eyed expression he usually wore had melted away, replaced by something sharper, more real. His green eyes held an edge that would’ve shocked most of his classmates.
Bakugou Katsuki sat in the armchair nearby, his own mask of constant aggression relaxed into something more comfortable. He’d been watching Izuku for the past ten minutes, recognizing the signs. They’d known each other too long for Bakugou not to notice when his childhood friend was reaching a breaking point.
“Kacchan,” Izuku said, his voice lacking its usual cheerful lilt. “I’m bored.”
Bakugou snorted, a smirk tugging at his lips. “Yeah? Getting tired of the whole ‘sweet innocent Deku’ routine?”
“You have no idea.” Izuku sat up, running a hand through his green curls with obvious frustration. “Do you know how exhausting it is? The stammering, the crying, the constant analysis that everyone thinks is ‘so cute.’ I’m tired of acting.”
“Then stop.”
The simple statement hung in the air between them. Izuku’s eyes snapped to Bakugou’s face, searching for something—permission, maybe, or understanding.
Bakugou leaned forward, elbows on his knees. “I’m serious. We’re not kids anymore, Izuku. I already apologized for all that shit I put you through. We’ve had each other’s backs for months now. The real you? That’s the person I’m actually friends with. Not the mask you wear for everyone else.”
A slow smile spread across Izuku’s face, and it was nothing like his usual bright, heroic grin. This one was sharp, dangerous, exciting. “You know what? You’re right.” He pulled out his phone, fingers flying across the screen. “Let’s make this interesting. Let’s invite Tenko and the League to our group chat.”
“Now you’re talking.” Bakugou’s grin matched his. “But you know what this means, right? If you reveal this, there’s no turning back.”
“Good. Acting soft is annoying as hell.”
“What’s annoying as hell?”
Both of them looked up to find Todoroki Shouto standing in the doorway, heterochromatic eyes fixed on them with unusual intensity. He stepped into the room, closing the door behind him with a soft click.
“The masks we wear,” Izuku said simply, not bothering to put his fake personality back on. Not for Todoroki. Not anymore.
Todoroki was quiet for a moment, then moved to sit on the couch beside Izuku. “So you’re giving up the act in class?”
“It’s getting tired, playing the mask all the time.” Izuku shrugged, something calculating entering his expression. “What about you, Shouto? Still pretending you hate your brother and your father?”
The temperature in the room dropped slightly, frost creeping across Todoroki’s right side before he controlled it. But when he spoke, his voice was steady. “No. I think I’m done with that too.” He looked directly at Izuku. “I know Dabi is Touya. I’ve known for a while.”
Bakugou let out a low whistle.
“He has these soft eyes when he looks at me,” Todoroki continued, his usual monotone cracking slightly with genuine emotion. “Even when he’s trying to fight me, but he never actually tries to fight me. He always picks other teammates instead. He’s protecting me, even now. And I’m tired of pretending I don’t see it.”
The door burst open—or rather, it was opened with perfect, precise timing by Iida Tenya, who stepped through with his characteristic rigid posture. But there was something different in his eyes. Something wild barely contained beneath his proper exterior.
“So our fronts are all coming out tonight?” Iida asked, pushing his glasses up his nose. The gesture was the same, but the energy behind it was completely different.
Izuku blinked. “Tenya? You too?”
“Me too.” Iida sat down in the remaining chair, and for the first time since any of them had known him, he slouched. Actually slouched. “What, did you think I enjoyed being the tame one all the time?”
“I mean—”
“Being the class president and acting responsible every second of every day isn’t my fucking style,” Iida said, and the curse word sounded almost foreign coming from his mouth. Almost, but not quite. “I like cursing. I always laugh at Katsuki’s insults, but I can’t show it in class. Do you know how hard it is not to crack up when he calls someone ‘extras’ with that ridiculous scowl?”
Bakugou looked personally offended. “My scowl is not ridiculous, Four Eyes.”
“It absolutely is, Explosion Boy.”
Izuku started laughing, and it wasn’t his usual nervous giggle. This was genuine, unrestrained laughter that made his eyes crinkle at the corners. “Okay, okay. This is happening. We’re really doing this.”
He pulled up his phone again, his fingers hovering over the screen. Then he looked up at his friends—his real friends, the ones who apparently had been wearing masks just like him.
“Let’s have some fun now,” Izuku said, and his smile was absolutely wicked. “Go wild, you three. I’ll inform Shinsou and Denki, but I’m guessing they overheard us anyway.”
As if on cue, purple hair appeared over the back of the couch, followed by Shinsou Hitoshi’s tired but amused face. “Been here the whole time. Do you people not notice a six-foot insomniac sitting in the corner?”
“Dude, FINALLY!” Kaminari Denki’s head popped up from behind the other couch, where he’d apparently been lying on the floor. “I’ve been waiting for you guys to crack for MONTHS! Do you know how hard it is to keep my mouth shut when I know Midoriya has a brother in the League? Or that Todoroki and Dabi are definitely related and having weird complicated sibling moments during fights?”
“How did you—” Todoroki started.
“I’m not as dumb as I pretend to be,” Denki said cheerfully, vaulting over the couch to join them. “The dunce act is useful. People tell you things when they think you won’t understand.”
Shinsou nodded slowly. “And I’m in General Education, remember? Nobody watches the support course kid who got transferred. I see everything.”
Izuku looked around at the group—at Bakugou’s fierce grin, at Todoroki’s slowly melting ice facade, at Iida’s uncharacteristic slouch, at Denki’s sharp intelligence finally showing through, at Shinsou’s knowing smirk.
“Alright then,” he said, opening a new group chat on his phone. “Let’s invite my brother and his friends to talk. It’s time we stopped pretending to be heroes and villains and started being honest about what we actually are.”
“And what’s that?” Bakugou asked, though his grin suggested he already knew the answer.
Izuku’s fingers flew across his keyboard as he typed out a message to a number only he had. “People who are tired of playing by rules that don’t make sense. People who are tired of wearing masks. People who want something real.”
He hit send.
[Unknown Number]: Hey Tenko. Miss me?
[Unknown Number]: Got some friends who want to meet the infamous League of Villains.
[Unknown Number]: Interested?
The response came almost immediately.
[Crusty Big Bro]: …Izuku? Is that really you?
[Crusty Big Bro]: Are you FINALLY done playing hero?
[Unknown Number]: Not done. Just done pretending.
[Unknown Number]: There’s a difference.
[Crusty Big Bro]: I’m listening.
Izuku looked up at his friends, at the anticipation and excitement and relief on their faces. Relief that they didn’t have to pretend anymore. Relief that they weren’t alone.
“It’s on,” he said simply. “Hope you’re all ready for this.”
Bakugou cracked his knuckles, small explosions popping in his palms. “Been ready.”
Todoroki’s left side ignited with flames, perfectly controlled. “Me too.”
Iida adjusted his glasses, a manic edge to his smile. “Absolutely.”
Denki’s electricity crackled across his fingertips. “Hell yes.”
Shinsou just smirked. “Took you long enough.”
Outside, the sun continued to shine on U.A.’s peaceful Sunday afternoon. But inside the dorms, six students prepared to shatter every expectation anyone had ever placed on them.
The masks were coming off.
And nobody was going to see it coming.
