Katsuki's Twin

Imagine Koyuki being a villian

This Imagine was requested by AmandaG_LovesPanda

What if...Koyuki became a villain and his boyfriends were Dabi and Shiggy?

Koyuki is obviously going to be aged up.

Koyuki felt like he was always in Katsuki's shadow, he just wanted to be able to prove he was strong all on his own. The only support he felt he had was his dad, but his dad did whatever Mitsuki told him. When Koyuki turned 20, he moved from home, telling his parents he was going to live farther away and go to a different hero school. Katsuki was mad that he no longer had backup. Koyuki no longer felt like they were brothers, more like a slave to every beck and call.
When he moved out, he really just went to become a villain and be a part of the LOV. He felt that heroes took everything for granted just because they had the power they were born with. Koyuki finally decided enough was enough, it was time for revenge.

Soon after joining the league, he found he had crushes on both Dabi and Shiguraki. He felt confused, whether it was okay to fall in love or if it was useless because they were straight or just didn't like Koyuki. He didn't think either of them would have feelings for him or want to be in that kinda relationship. He was wrong.

Dabi and Shiggy figured out if they got up close with Koyuki, his bright red face was an obvious giveaway. They both realized they were going to fight over him now. They made it into a contest on who could win his heart, constant flirting and gifts. It shocked Koyuki why they suddenly were so nice and flirty while also giving his favorite food, spicy ramen with milk tea. Koyuki would blush and shy away whenever Dabi would whisper in his ear or when Shiguraki holds his hand with four fingers. Koyuki thought they were just messing with him, but he also knew Shiguraki wasn't the type to do such a thing. Dabi tried to act cool about every little thing he did for Koyuki as he did it to everyone else, and that's what Koyuki thought too.
Koyuki ignored his feelings, he didn't what to hype himself for thinking someone would actually want to be with him. The day that changed it all, when Dabi and Tomura both confessed at the same exact time. Koyuki was confused, why would they even bother with him? Why would Yomura play along in a game of truth or dare? But it wasn't a dare, they both loved Koyuki as much as their villainous hearts would let them.
Koyuki didn't know what to say, but to prove they were both being serious, Dabi kissed him. Siggy pushed Dabi off of Koyuki to do the same, both trying to show their dominance. Koyuki's blush could have reached Mars.
"So you guys are for real?"
"Yes."
Koyuki didn't know who to pick because he loved both of them, he found them equally attractive, both their personalities were so different. Koyuki felt like crying because he had to chose. And so a single tear slipped from his eye.
"I-I don't know, I have feelings for both of you." He looked down as he was ashamed.
Both Dabi and Shiggy we're shocked by his confession. Now no one knew what to do. They all sat in a thick silence for what felt like years, then Dabi broke out a sigh.
"Hmm, what if...you could have both of us?"
Tomura and Koyuki looked at him as if he were insane.
"What do you mean?"
"I mean" he let out another sigh. " what if we all were in one relationship where you could have both of us and we could have you."
Shiguraki was speechless.
"Y-you want to share me?"
"Not exactly, but I don't want to force you to choose between us, and if rather have you for myself but this way I could still have you, but so would musty over here."
Shiguraki contemplated if he was really willing to share Koyuki with Dabi, but if he would have chosen him, then Shiguraki would be left out.
"Alright, I guess im in too."
Dabi nodded at Shiguraki.
"So, are you in?"
Koyuki couldn't put words into how happy he was. So he hugged both of them and let his tears all fall out.
From then on Dabi and Shiggy were extremely protective of him and did not let him go on missions unless at least one of them were along. Koyuki didn't mind their protectiveness too much, he felt happy knowing they loved him that much.
The three of them always spent the mornings cuddling and Dabi ended being the first to get up and make breakfast for them. They went on dates Fridays, it would either be staying home to watch movies or taking Koyuki to more secluded areas. It didn't matter to Koyuki where they went as long as they were together. Sometimes Shiggy would be too busy with work, so Dabi could have Koyuki to himself.
