Sorry for late update. Also, sorry for it being shorter than usual.  Here's a picture of Shinso in his cat shirt. I went for pens and Gouache paint (second time I have ever used them and I kind of love yet hate the paints?). I love gouache, but it's a pain to get the right shade of skin with them DX

Past:

Shouto watched as Touya left, declaring he was leaving for good. He was only 5 at the time, and father was getting rather brutal with the training. Touya wouldn't even take them with him. He was leaving them with that monster. Though, he probably wouldn't  be able to get away if he tried to get them all out. Nonetheless, Touya was abandoning them. And damn if that didn't hurt like a bitch. Still, he was glad at least one of them could escape their brutal father. Maybe one day they would meet again.

Now:

Dabi had put a quirk suppressant collar on Shouto. Izuku had made six of them and gave one of them to Dabi in case he ever kidnapped someone. This one had red cushioning in it instead of purple like Shinso's collar. Dabi had also tied him down to his computer chair and was now sitting on his couch as he waited for his baby brother to wake up.

Shouto stirred with a groan. He tried to move but found himself restrained. He then tried to use his quirk but found he couldn't use it. Suddenly aware of the severity of his situation, his eyes snapped open. He looked around the small room he was in. There was a computer to his right, a door to his left, and a small, black couch in front of him. The walls were black and the carpet was blue. The walls had a few pictures on them; they were of the Todoroki family. The man sitting in front of him was staring intently at him.

"Hello, Shouto." he drawled

Shouto raised an eyebrow. "Am I supposed to know you?" He tugged at his restraints. "This is about my Asshole of a sperm donor, right?"

"While I do hate that man as much as you probably do, this isn't just about him. I'm kind of hurt you don't even recognize me. Is it the hair dye? I doubt there are that many people out there with my scars." Dabi smirked.

Shouto's eyes went wide as he realized who was in front of him. "T-ouya?"

"In the flesh, baby brother." Dabi grinned.

"But how? Why? What happened to you?" Shouto asked.

"After I left, I ran into Siren. I saved him from his parents actually. A few months later found both of us being taken in by Present Mic. Funny how it's the villain who knows how to treat children right as well as how to love them. Anyways, I found myself a family that accepts me for my quirk even though my body doesn't work with my quirk. I finally fit in. It was purely coincidental that I ran into you. Plus, I get to see you again and piss off the old man. It's getting two birds with one stone." Dabi smiled.

"It's nice to see you again, Touya. Despite the circumstances that have lead to us meeting. How long exactly do you plan to keep me here? I doubt it's just for a day if you're planning to piss father off." Shouto sighed.

"Why, for the rest of the internships of course!" Dabi laughed.

"I guess that's one way to piss father off." Shouto replied.

"Indeed. Now, are you going to behave, or am I going to have to drag you around in restraints?" Dabi questioned.

"I'm not dumb enough to try to take you on without my quirk and no knowledge of where I am. Not to mention the fact that I don't know how to get out of this place." Shouto deadpanned.

Dabi clapped his hands with a smile. "Good. Now, how about we go and hang out with Siren and his hero? " He then spoke up a little louder, "Allow Shouto Todoroki to leave room."

"Access granted."

Dabi untied the emotionless teen and grabbed him by the upper arm. "Let's go, Shouto." Dabi led him out of the room and down the hall into the main lair. Dabi dragged him towards the elevator and entered the key code to open it. Shouto was silently observing everything he could see and storing it in the back of his mind for future reference. He looked at the inside of the elevator with a raised eyebrow.

Dabi tugged him into the elevator and entered another code to go down a few floors. "Sorry I didn't take you guys with me when I left, but you know how it is. It's hard enough as it is to leave that place on your own. But with multiple people? Impossible. If I could, I'd take you away from there forever. But I can't. You're a hero in training and I'm a villain. I can't do that to your future career. But I can occasionally steal you from the old man every once and a while.""

"It's fine. You were trying to escape and taking us with you would have cost you your one chance to leave. Although, a phone call or postcard would have been nice. But I guess being kidnapped works as well." Shouto reassured.

The elevator opened and they walked into to hall and through a door on their right. "Welcome to the gaming room, Baby Brother." Dabi brought Shouto to the very back, where the gaming chairs and giant tv were and released his grip on his arm. "SIREN?! I'M BACK! Grant Shouto access to only this room and the bathroom across the hall."

"Access granted."

A few moments later, Siren came down the stairs dragging Shinso with him. "Aw, did you kidnap your brother? That's so sweet!" Siren teased as he and Shinso walked over to them.

"Yeah, well I'm keeping him here till the end of his internship." Dabi smiled.

"Anything to piss off the old man?" Siren asked amused.

"Eh, that and to see how much my baby brother has grown." Dabi laughed as he wrapped his arm around Shouto and ruffled his hair.

Shouto just blushed from the unusual affection and attention he was receiving. He was used to either being yelled at, stared at, or ignored. But this? He was not used to this. When was the last time he was hugged or smiled at? Has it really been that long? It's sad how a villain (his brother nonetheless) is the one to treat him with affection. Sure, his other siblings loved him, but he rarely got to see them because of father. And his classmates usually avoided him. The only person to even try to understand what he was going through or feeling was Shinso. And he was being a jerk to Shinso like everyone else! Granted, he wasn't judging him like everyone else, but he didn't stand up for him either. He just ignored his classmate, refusing to socialize. Can't do something you never learned how to do after all. Speaking of his sleep-deprived classmate, he was clutching a cat plush in front of him while Siren had a vice grip on his arm. W-was that a Ganriki Neko shirt? OMG, it was! 

"Not a word, Todoroki, not a word." Shinso hissed as soon as he saw the look on Shouto's face when he saw the shirt.

"Hey, if you like to wear hideous cat shirts, fine by me." Shouto remarked.

"At least I don't go accusing people of being the love child of their teacher." Shinso snarked.

"Not my fault they act like they are family. Seriously, Aizawa-Sensei is such a dad to you. Are you sure he isn't your dad?" Shinso just glared at Shouto. "Fine, fine. He's not your dad. Got it."

"So, video-games?" Siren questioned Dabi.

"Video-games." Dabi affirmed.

Siren turned on his mic and said, "Toga, we need two more chairs in here and please get some clothes for Dabi's temporary guest. He should have some in his guest bedroom. Yes, I'm referring to his old clothing from when he was younger." Siren asks Shouto what clothing size he is before informing Toga of his clothing size. (a guest room is literally like Shinso's temporary bedroom. It's a sort of prison bedroom to keep any hero one of them decides to kidnap in while being ably to keep an eye on them from the bedroom next to it.)

Siren dragged Shinso over to his chair and forced him to sit in it. He then attached one of the two chains to his wrists before taking the other off of the chair. He then attached it to the other chair and said, "The chair is now ready, Dabi."

Dabi grinned as he grabbed Shouto's arm and dragged him to the chair to chain him to it. "Unless you need to go to the restroom, you're going to be spending the next few hours in this chair. Sorry, Shouto, but it just a precaution since you just got here and might get some rather idiotic ideas."

"We're not playing Overcooked again, are we? Because I will burn the kitchen down if we do." Shinso smirked.

"You cheeky little-" Siren groaned before continuing," we are definitely playing only that game tonight. We'll play Animal crossing tomorrow, but I want to make you learn how to play right and not be such a pain in the game!"

"What is this Overcooked you speak of?" Shouto asked.

"It's a video game. Did you dad not let you play games or something?" Shinso responded.

"All I ever did growing up was sleep, eat, and train. Never touched a video game or movie in my life." Shouto sighed.

"... DABI, YOU CAN HAVE THE GAME ROOM TOMORROW FOR GAMES AND MOVIES CAUSE OH DEAR LORD! HE NEEDS TO EXPERIENCE THE MOVIES AND GAMES HE NEVER GOT!!!" Siren dramatically wailed.

"Quit being dramatic; that's Nii-san's job." Dabi laughed.

~~~~With Eraserhead and Present Mic~~~~

Eraserhead was beyond his snapping point. His student was still captured, he was tied up and gagged while being forced to listen to horrendous music, and Present Mic was dancing around as if it was some big joke to him. It probably was a joke to him since he tends to find everything to be some sort of big game. It was infuriating, really. All that Eraserhead knew was that if he had to endure one more minute of this music, he was going to kill that blond buffoon. He had managed to spit out the gag earlier, but that attention-seeking menace had just replaced it with duct tape. Duct tape! Not just any Duct tape. Present Mic themed Duct tape. Where the hell he managed to get it from, Eraserhead would never know. But damn did it piss him off.

Thankfully, Present Mic stopped dancing around like some Disney villain and walked over to the TV to turn off the horrid music. He then strolled over to the hero and leaned in with a smirk. "Now, are you going to chill, or do I have to drug you to get you to cooperate?"

Eraserhead stiffened at the suggestion of being drugged. He hated being drugged. Especially when Present Mic drugged him because whatever he uses leaves him feeling small and vulnerable and he hates it. And Present Mic knows he hates it and he just used the threat of it against him like the asshole he is. Present Mic hummed with approval when Eraserhead hung his head in defeat. "Good Boy."

Present Mic pulled the duct tape off of Eraserhead's mouth and then leaned out of his face.

"You're despicable." Eraserhead hissed.

"Aww, is someone mad?" Present Mic mocked.

Eraserhead just glared at him. It wasn't effective. Present Mic just laughed. He laughed! What a jerk! "Am I supposed to be happy that I was kidnapped?!"

"No, I suppose not. Although, you've got to admit that you walked right into this one." Present Mic teased.

"Why can't you just give me one week- just one week without kidnapping me? Is that too much to ask?" Eraserhead said exasperated.

"Yeah, no. Sorry Shouta, but where's the fun in that?" Present Mic giggled.

Eraserhead groaned in frustration.  Present Mic was impossible to deal with. How someone so childish and showy was so hard to capture was beyond him. Like, why couldn't any of them defeat him? Even All Might had a hard time fighting him! And what the fuck was up with his obsession over him? Like, out of all the heroes, why fixate on him?! It just didn't make any sense.

"What are you planning this time?" Eraserhead asked.

Present Mic grinned evilly. "What? I can't just admire your awesomeness from afar?"

"You do that enough without kidnapping me. You've got something planned. So just get on with it already." Eraserhead gritted through his teeth.

"You've got me there. I was mainly just planning on messing with you since you're so uptight right now." Present Mic smirked.

"Of course you were." Eraserhead grumbled.

"Aw, don't be like that Eraser." Present Mic teased.

~~~~A few hours later with Siren and the others~~~~

Shouto had changed into the clothes Toga brought with the chairs. He was now in a band t-shirt and black cotton sweat pants. he was back in his chair and chained to it once more wondering who came up with the idea for a game that caused people to argue so much. They had made it to level 7 and curse words and death threats were being thrown back and forth over stupid things like grabbing the wrong item or dropping the tomatoes in the potato soup. Like, isn't it just a game?

Why where they getting so worked up over a video game? it didn't make any sense at all. Was he missing something? He was so missing something. Another thing to blame on his father he supposed. He was trying to chop up a tomato while Shinso was purposely messing up to annoy Siren. Dabi was desperately trying to help Shouto fix their score that Shinso was destroying.

They had eaten ramen for dinner thirty minutes ago and the ramen bowls were left on the floor forgotten. Shouto had no idea what time it was but he knew it was getting late.

"ALRIGHT!!! TIME FOR BED! I AM NOT HAVING A REPEAT OF YESTERDAY! GAME SYSTEM OFF!!!" Present Mic yelled as he walked towards them.

Siren turned the game off and said, "Oh, hey Nii-chan. How was it with messing with Eraserhead?"

"He was rather feisty tonight, but I had fun messing with him. I ended up having to drug him before returning him to his home though. He wasn't being rational at the time."

Flashback about 30 minutes ago:

"I think it's about time we returned you home, huh?" Present Mic laughed as he went to cut Eraserhead's restraints.

As soon as Present Mic was done and walked around the chair to face him, Eraserhead jumped up and went to sock Present Mic in the face. Present Mic caught his fist with a look of disapproval before kneeing him really hard in the stomach and following with a swift kick to the head. Eraserhead fell to the ground with a painful groan. Present Mic crouched down to the ground in front of him and tsked.

"You're making it really hard to not drug you, Hero. But if that is what it will take to keep you cooperative until I get you to your house, then so be it."

Eraserhead tried to get up but Present Mic got on top of him and pinned his arms behind his back with one hand and pulled out a syringe filled with a yellow substance with his other hand. "I told you to behave or I'd drug you, Hero. Guess I'm going to have to give you enough to knock you out."

"N-no..." Eraserhead gasped out in pain. 

Present Mic injected the drug in Eraserhead's neck and the hero went limp within seconds. With a sigh, Present Mic got back up and picked the hero up bridal style. "Teleport to Eraserhead's house."

Within seconds, he was standing in Eraserhead's living room. (don't ask why he has Eraserhead's house programmed into his teleportation system, he just does.) He walked into the bedroom and laid the hero down on the bed before tucking him in. He then teleported back to the base.

"Anyways, you four should go to bed. And Dabi? Give me a heads up the next time you decide to kidnap one of your siblings."

Dabi nodded before unchaining Shouto and saying, "Allow Shouto to leave this floor."

"Access granted."

He then dragged his little brother out of the room and towards the elevator.

"Did he just say he drugged Aizawa-Sensei?" Shouto asked.

"Yes. Don't worry. The drugged wears off after 24 hours. Your teacher will just feel weak and small for a little while when he wakes up." Dabi reassured him as they entered the elevator.

"What did he give him exactly?" Shouto questioned.

"Just a sedative we made that makes people less likely to fight back. Nothing bad." Dabi laughed.

They let the elevator and entered the forth door on the right of the hall. Dabi unlocked the door and pushed Shouto in. "Right, here's your room. Don't try anything stupid. The bathroom is the door in the back, the door to the right goes to my room-it's locked. The clothes in the dresser might fit you, they might not. I'll make Toga buy you some if they don't fit."

Shout took in the white-colored room. Everything was white. The carpet, the walls, the furniture. All white. The bed had a fluffy white blanket on it that made Shouto almost upset he would have to go home eventually to his pathetic bed at home.

"Restrict Shouto's access to just this room." Dabi commanded.

"Access granted."

"Goodnight, baby brother. Do try to get some sleep." Dabi drawled as he left the room and closed it. 

Shouto sighed and turn off the lights. He crawled into the very soft bed and melted into it. He probably wouldn't want to get up tomorrow. 

Again, sorry for the shortish chapter.
