The Formula for Villainy

Fake Smile and Invincibility Facade

The light of the computer sears his corneas after days in the dark underground. "Master, I have an update for you. It's very good news,"

The voice coming from the monitor is nothing like he recognises. "Tell me,"

"The dear fallen heroes who killed Stain - they're here to join the League of Villains,"

Indeed, Izuku and Iida make the commitment to the league. All suspicion upon them disappeared after they revealed how they defeated Stain. Untrue - suspicion still very much exists, however with the Hero Killer gone the League is desperate for high-level, skilled quirk users. Beggars cannot be choosing beggars and the League needs as much talent as they can get. 

Izuku's dead eyes roam across the bar, staring at everything but not absorbing any of it. Oblivious to what's happening around him. The moment he blinks he'll have forgotten every detail of this room, and when he reopens them it'll be like he first stepped foot into this lair. Toga regards him with intense fascination, eyes bulging with excitement. The celebrity hero Izuku Midoriya, theirs to keep. But he did kill her crush. "Tell me, how did his blood look?" she asks sweetly. Batting her eyes.

Izuku barely hears, but just. He looks up at her with the same impassion he regards the rest of the bar. "His blood?"

"Mhmm," she grins, showing every tooth. "I have a blood quirk too you see! We'd have been perfect for one another. I would have loved to have seen what his looked like in person..." she pouts. "But I had to settle for TV coverage of his murder," a disappointed sigh follows. 

"Excuse me, but will you stop harassing my boyfriend?" Iida sits in a wheelchair, the one the doctor gave Izuku. "Who's in charge here?"

"I am," Shigaraki emerges from the room in which sits the computer. Seeing him without a hand over his face makes Iida regard him as much more human than monster. ""Master has generously decided not to kill you both,"

"Welcome to the League of Villains!" Toga announces with a squeal.

"Indeed. But know that if you try anything Izuku Midoriya," he stares at the younger with a sadistic glint in his eye. Immense satisfaction at is power over the two heroes. "I will dissolve your boyfriend from the legs up. And you will watch him rot,"

For the first time since walking in this door, emotion returns to Izuku Midoriya. Entirely fear, no place for hatred anymore. "P-Please Shigaraki..."

"If you do as I say, you have nothing to worry about," he grins too, his teeth calloused and rough compared to Toga's. The same bloodthirsty grin.

"What happens now huh?" Dabi asks from the door, arms folded. He isn't exactly on board with this but the kid and the injured one seem to have switched sides entirely. He knows a villain when he sees one, knows someone scorned by the toxic hero-villain society formed around nothing more than authoritarianism at its finest. Dabi disliked the Hero Killer Stain but most of hat he said was inherently true.

"Well now that we have these two," Shigaraki reaches down and traces under Izuku's chin. One finger, two, three. The child trembles under the touch, panicked breathing building on his chest. One finger and he dies. But Shigaraki seems intent on keeping him alive. He's just toying with him. The fingers are carefully removed from his throat. "We'll make the 'kidnapping' official. Parade them in front of the school, that'll make All Might tremble in his bones,"

"Splendid idea!" Shigaraki agrees.

Izuku withdraws into his guilt. He doesn't want to make All Might feel even worse than he must already do. So much stress weighing him down. Crippling him under the weight of depression and hopelessness. Izuku felt that way in the moments he rushed to Iida's side in the alleyway. When he thought he might get killed by Stain. And there was nothing he could do to help.
