The dull pain in the back of Katsuki's head was the first feeling he felt when he woke up. He went to feel it, but only got to his shoulders before he heard a clang and felt a tightness around his wrists.
"The fuck?" He grumbled, trying to pull his hands out of the chains.
He pulled and pulled until his wrists became sore, the skin underneath the chains wearing down. His head shot up when he heard a door opening across from him.
Katsuki's eyes traveled to the man's face. He looked younger than he was, a decade at most. His hair was untamed and he looked like he hadn't slept in weeks. His small fram was covered by a large lab coat. The thing that had unnerved Katsuki the most, though, was the sweet smile upon his face.
"Hello, Kacchan," The man said, bringing Katsuki back to reality.
He snarled, trying to move forward as if to attack the man. He flinched slightly, but the smile on his face didn't leave.
"Don't worry, I'm not going to hurt you. There's nothing to be afraid of," For someone who chained a person up, his voice was unusually soothing.
Katsuki snarled at the words, his hands tugging on the chains once again. "Do I look like I'm fucking afraid to you? Unchain me and I'll beat your ass!"
The man gave a small chuckle before saying, "Now why would I do that? I've been waiting for this moment for years, the last time I want is for you to get away."
The words confused Katsuki, but the snarl didn't disappear.
"What the fuck do you mean?" Katsuki growled, a bit quieter this than the last time he spoke.
The man moved forward, his gloved hands coming up to his arms, as if he was hugging himself. The grip made his fingers sink into his arms, the tearing of fabric hit Katsuki's ears.
"I've been watching you, of course. And, let me tell you, I really liked what I saw," The man's smile became psychotic. "You really are amazing, Kacchan. I hope you don't disappoint me."
The man's hands moved down. One to his side and the other to his pocket, pulling something out. Katsuki recognized the object almost immediately. It was a syringe, filled with a strange, green liquid. He held it carefully, as if he was afraid he was going to break it.
He slowly moved towards Katsuki, his hand that wasn't holding the syringe twitched immensely.
Katsuki began to panic slightly, but there was no way in hell he was going to give this man the pleasure of seeing him freak out.
"If you even come near me with that goddamn thing, I fucking swear-" Katsuki was cut off but a villainous laugh.
"I'm sorry to say, Kacchan. But there's not a lot that you can do for yourself. I've clearly got the upper hand in this situation. So, please, don't try to resist," The man was at Katsuki's feet now.
He bent over, just so he could reach him at arms length. Katsuki tried to reach for the man, but the chains kept him from doing so. Luckily, his legs weren't chained.
He gave the man a small smirk before moving onto his back, his arms above his head in the chains. The man let out a little gasp before trying to move away. But, Katsuki was quicker than that. He landed a kick right in his stomach.
The man let out a yelp and moved back so he was out of Katsuki's reach.
The man gave Katsuki a sad smile, "I really didn't want to have to do this, Kacchan, but you've given me no choice."
Standing up, he put the syringe in his pocket, only to pull out another one. This time, it was filled with a clear liquid. He moved towards Katsuki's feet once again and stepped on his leg.
Katsuki let out a growl, trying to push the man off of him with his other leg. The man moved up more so he was at Katsuki's thigh. He looked down at him, giving him a sympathetic look.
The man sat on Katsuki's thighs, straddling him. As Katsuki was about to headbutt the man, he moved his hand on Katsuki's forehead face, pushing his head back. He stabbed the syringe in Katsuki's neck. His arm's jolted towards his neck, trying to pull the damn thing out of him, but he could only get so far with the chains pulling on his wrists.
The man slowly let go of Katsuki, but he still sat there. Watching him.
As Katsuki became drowsy, he let his head fall. His eyes moved towards the name tag on the man's lab coat.
"Damn you, Deku," He said, before everything went black.
