“Why the fuck would you bring ____ here?!”
“Dabi, shut the fuck up.”
You can hear ‘Dabi’ and Tomura screaming at each other. It was more of Dabi yelling while Tomura told him to shut up, repeatedly. When Tomura’s voice dropped, though, chills went up your spine. You sat on some dingy couch, not able to help but listen in on Dabi and Tomura. Your eyes were glued to the floor and you hugged yourself tightly.
The couch shifts and you reluctantly look over. The blonde from earlier is sitting beside you, smiling widely. Either she knows something that you don’t, or she knows something she shouldn’t.
“Do they know?”
You give her a confused look. “About what…?”
“That you’re…” Her smile somehow widens, and her voice drops to a whisper as she laughs out the remainder of the sentence. “That you’re an omega.”
“Hush!” You're quick to quiet her down, “But, that hasn’t come up, no…”
“Don’t worry! Your secret's safe with me!” She crosses an ‘x’ over her heart before winking, “That is until you go in heat…” She giggles and covers her mouth, “I’m Toga by the way!”
“I’d introduce myself but I’m afraid everyone already knows who I am.”
Toga shoves you, a little harder than she intended to, and you fall over onto the other cushion with a yelp. You sit up once you hear footsteps, and your eyes wander to the doorway. Tomura comes in, Dabi hot on his trail. Tomura is very much actively ignoring Dabi. Dabi is very much actively pissed.
“____, get up.” Dabi turns his attention from Tomura, to you. Your eyes shoot up to him and you're sent reeling back when you notice he mad he still looks. You can’t help but stand, and Dabi seems to realize. His expression drops, before a wicked grin spreads across his face. “____, you- You’re an omega.”
You’re sat there, blinking. Shigaraki looks from Dabi and to you, and you see him inhale sharply. Your throat is suddenly dry and you want to run. And fast. But, instead, you stand where you’re at, staring at Dabi and Tomura with a sense of fear. You hadn’t tried to deliberately keep it from them, specifically. But you were trying to deliberately keep it from literally everyone.
“You stink.” Tomura huffs.
Toga lets out a loud laugh, grabbing her stomach. You look at her with a defeated look. You straighten up, “Fuck it,” You mumble. Looking at Tomura and Dabi you let out a sigh, “Yeah…” Suddenly, you’re hit with a burst of rage-filled confidence, “But I don’t know why you care, exactly. Don’t you want me gone?”
Dabi’s eye twitches. There is a heavy silence. He begins to stalk towards you, a predatory stare in his eyes. You don’t fold. He circles you, inhaling your scent. Once he’s facing you again he meets you at eye level and the look in his eyes is striking a fear in your heart that you’ve never felt before.
“I could easily kill you, ____-”
“What’s stopping you?” You don’t bite your tongue, but you will soon wish you had.
“Me.” Shigaraki approaches the both of you, pulling Dabi away from you. The feeling of everyone’s eyes on you is starting to get under your skin. The feeling of absolute dread from your dead best friend hating your fucking guts is starting to cause your eyes to water. You’re so fed up with the tears you try to blink them away.
“Quit crying.” Dabi groans.
“Dabi, quit being an ass.” You turn around and find a tall woman standing there. “Leave her alone. She’s one of us now-”
“Magne-” Dabi looks like he’s going to combust.
Magne and Dabi seem to be thinking about killing each other, and you're stuck next to Tomura. You look at him and take a moment to take everything in. You inhale slowly and catch a musky scent. Suddenly you’re grounded. You notice under his arm is the stuffed animal you gave him earlier, he is still holding it. You feel yourself smile and then quickly realize the room is silent.
You look around only slightly worried this time, “What?” You give them all a funny look.
“You smell… Good!” Toga leans over, smelling you.
Seemingly without thinking, Dabi places his palm against Toga’s forehead and pushes her away. The blonde glares up at him and one side of her lip curls upward.
“Don’t get so close-” Dabi snarls. Something seems to click in his brain, you can almost hear the connection. He is quick to catch himself, “Don’t get used to her being here.”
“Oh yeah, that’s what you meant,” Magne laughs.
Tomura’s hand is on the small of your back in an instant, you can feel not all of his fingers are touching you though. He begins to lead you off while the others argue. “I’ll show you your room since the others have no fucking manners.”
The place is pretty dingy, but you agreed to come with him. You willingly followed a villain, thinking nothing about your future living situation. He showed you your ‘room’ if you could even call it that, and let you go.
“We’ll meet in the morning. We have a lot to go over.”
You nod and go towards your bed. You sigh a little too loudly as you lay down. The only things on your mind are Touya, your childhood, and how the fuck both of you ended up here. You try your hardest to not cry, but you can't help it. You decide it's best to cry now rather than later, in front of everyone, so you let the tears fall.
You hold yourself and begin to sob. Touya hates your fucking guts, you willingly became a villain, and you have nothing to comfort you. You briefly think about asking for that plushie back but you figure that would probably make you not a part of the league, much less life, any longer.
You hope tomorrow is better. You hope Dabi can at least warm up to you. And you hope you didn't make the wrong choice.
The next day doesn't start out rough. You meet and become acquainted with the rest of the league. Toga is the nicest. Possibly the creepiest, but definitely the most accepting of you.
"So-" Toga is clinging to your side, staring at you with curious eyes. You nod at her, becoming curious yourself, "-why didn't you get into U.A.? Shigaraki said you were denied-"
Your eyes move to Tomura and your stare becomes blank. You blink once or twice and notice he doesn't care. You look back at Toga and rub your sweaty palms down your thighs.
"Aw," Dabi feigns sympathy, "you seem to have struck a nerve…" He pouts at you and you want to swing. But he can easily overpower you, or burn you to a crisp, so you ignore the feeling.
You keep your eyes on Toga, deciding ignoring Dabi is the best plan of action. "I haven't always been the most stable when it comes to my Quirk… they said I was a liability. It made it worse when I just… didn't pass the exam. I mean I'm sure I could pass now, but I'm a little old-" You begin to ramble. "That'd be weird, some woman going to school with teens, and the woman still can't even control what the fuck she's doing-"
"What is your quirk exactly?" Kurogiri politely interrupts you, stopping the rambles.
"I can… fix the probability of things. I'm very lucky, or, if I start to overthink the situation… very unlucky. That's where the problem lies. I almost killed some poor kid because I completely altered the exam. I didn't mean to! It just… happened. And when it did, I got the boot. Uh, very quickly. I can say though, I'm only alive now because of my Quirk. It's very useful when someone's holding you at gunpoint!"
You sound more cheerful than you intend to, causing the whole room to shift. But Toga is very intrigued, and seems to want to know more. Suddenly, it feels like it's just you and her in the room, and you're growing more comfortable.
"He pulled the trigger but nothing happened. It gave me just enough time to book it. I've been keeping to myself ever since, really. I mean, he-" you stop yourself. You don't want to say anything else once memories of that night flood back and you remember just why you don't talk about it.
Dabi, lounging on the sofa, gives you a funny look, "He? Who is he? What the fuck were you doing to be held at gunpoint? How did you get in that situation?" His voice is suddenly not so full of venom, he seems slightly curious, until he finishes his thought, "You aren't even a hero."
You're so tired you, you want to snap, and before you can bite your tongue you do. "He isn’t important. Anyway, you don’t fucking care about me anymore-”
Dabi looks like he's about to break your neck. “You don’t know a fucking thing about me!” He stands up and you feel the urge to cower. You stare at him with furrowed brows, and your face drops.
“No!” You stomp your foot, “Maybe I don’t know anything about you. But I used to! I knew that you were my friend. That you did care for me, as much as some kid could! Then you fucking died. You were gone and I was left alone. No closure other than your fucking jaw bone being found. I don’t know what happened… But I know I mourned you, I grieved you!” Hot, angry tears are falling down your cheeks and by the look on Tomura’s face you ‘stink’ again. “I fucking cared about you. Not a day goes by where I don't miss Touya.”
You pause and rake your fingers through your hair. Your breathing is ragged and your chest is heaving. Snot nosed and crying. But you aren’t done.
“But, but-” You stumble, and words aren’t working.
“‘But- But-’ what? Speak up.” Dabi takes a step closer to you.
This causes you to scowl, and hard. You take a step back from him and tear in again, “I miss Touya, but I don’t fucking know you. You are nothing to me! I won’t bother you about your damn past. As far as I’m concerned, Touya is dead. Always will be.”
The room is silent and Tomura is smiling widely. You push past Dabi and you see him tense, like he’s going to grab you, but he doesn’t.
“You aren’t a very submissive Omega,” Dabi growls, causing you to stop.
You turn back to him and your fists clench, “Good!” You scream, every ounce of you tensing up. Your eyes screw shut and your voice cracks. You turn back around and begin to walk off, until Tomura speaks up.
“____, stop.”
You freeze. You turn back to Tomura and cock your head. Out of your peripheral vision you swear you can see Dabi tense. His face contorts and he waits for what’s coming next.
“You’re training with me today. Everyone else can get back to their duties.” You only nod, fear pouring into you again. Dabi begins to protest and Tomura puts a hand up, “Fuck off, Dabi. Go do something productive.”
“Fuck that, and fuck you! And fuck her!” He points at Tomura and then you. You lean in closer to the blue haired villain and want to die.
“You’re just mad because you have no bitches.”
“And your crusty ass does?!”
“Dabi,” Tomura, seemingly a little bothered, sends Dabi on his way. “Go. Do something. Productive.”
Dabi groans and leaves. Leaving you with Tomura, all alone. You were alone with him before, but it was different. You were in a public place, and you weren’t even part of his team yet. Now, you were one of the villains, he knew you were an Omega, and he did not have to hold back the way he did before in public.
You hope that training goes relatively easily and you get done quickly.
