Chapter 2: Wanna Bet?

(Y/N)'s POV
"This is your dorm, you can customize it however you want." Eraser informed me as he started walking away. Looking inside my mind filled with creative ideas of how I should re-design my room, before a childish voice pulled me back into reality,
"R.B" I looked slightly down to see Nejire looking up at me. Her eyes filled with wonder and delight,
"How are you settling in?" She politely asked. I looked down,
"I'm setting in fine, darling."
I answered, while looking back at her. Raising my eyebrows when I notice her gleaming smile. 'Guess she likes the nickname.' I thought, as I heard my name get called again, "What?" I said, as Tamaki came closer to me,
"Y-You need to i-introduce yourself t-to the s-students p-properly." He stuttered as I walked closer to him. Stopping right in front of him I looked up, he was clearly nervous. I looked in front of me and kept walking, trying to figure out where the classroom was that Eraserhead showed me.
Opening a random classroom door, I walked in. There I was greeted with multiple confused eyes. All while my own were darting around the room, trying to locate the little girl from earlier. That's when I heard Eraserhead's voice,
"Class, this is (Y/N)"
"R.B" I interrupted. Eraserhead just looked over to me, then back at his class, "Right, this is R.B, she's Eri's new trainer."
Most of the class ooo-ed and awed at this, while one particular blonde scoffed.
"Do you have a comment, Bakugo?" The ravenette asked, as the blonde stared daggers at me.
"Yeah, why didn't you just work with her?" He asked, before Eraser could answer, I did.
"Because I'm the best at handling my damn quirk."
I answered, as the blonde looked at me angrily, "The fuck did you say."
"I said, I'm the best at handling my damn quirk." I spat, as the class silenced. All of their faces displaying a look of shock,
"Where the hell did you even come from." He questioned, as I walked closer to his desk,
"Marci Island Quirk Center."
I answered, making the entire class gasp. "Isn't that the quirk center where kids are treated like prisoners?" The girl with the black ponytail asked, "Yeah, it is. I lived there for 10 years."
I answered, making the blonde's face twist in shock for one second, before reverting back to his angered face. "So, you're a former inmate. Big deal."
He replied, as I slammed my hands on his desk, "Alright then hot shot. You wanna talk shit? Then beat me in a fight."
I challenged, as the other students started whispering among themselves, "Alright then. Just know I'm going to beat your ass."
He taunted, as I leaned in close to his face, "Wanna bet." I said, as someone grabbed me by my waist and pulled me into their chest.
"I'm sorry for R.B disrupting your class sir." A familiar voice said. Turning around I was greeted with two completely sapphire blue eyes.
"No, it's alright, this could actually make a good example."
Eraser reassured, as he lead everyone to the training grounds.

Mirio's POV
Walking behind R.B, I thought about how much trouble she would cause if she kept acting like this. Upon arriving R.B threw her gray blazer to the ground, and unbuttoned the top buttons on her white button up shirt.
"R.B! You know you can change into a UA gym uniform!" Shouted Nejire, who had just jogged in with Tamaki right behind her.
"Nah, this is fine." R.B reassured, as Tamaki yelled, "B-But how are you going t-to use your q-quirk?!" R.B turned to him and smirked,
"I'm not."
She simply stated, making Bakugo look at her with murder in his eyes, "SO YOU'RE NOT GOING TO GIVE ME 100%?!" He bellowed, as she turned to him with a mischievous grin,
"I am. I'm going to give you 100% of my natural strength."
She said, as Eraser explained that the first one to fall for 10 seconds or more, loses. Right after explaining that, he let the two go at each-other.

Third person POV
Bakugo came running at (Y/N) instantly, immediately activating his quirk. Swiftly, (Y/N) dodged, swung behind him, and kicked.
Causing him to stumble forward. A look of shock appearing on his face for a millisecond, before returning to his murderous look.
Turning around and lunging forward, he grabbed her wrist and activated his quirk.
Pulling back, (Y/N) punched him in the nose with her undamaged hand. Turning to face her, Bakugo watched as she shook off the pain and kept punching.
Causing Bakugo to start playing defense. That was until she kicked his knee, causing him to fall, for more then 10 seconds.

(Y/N)'s POV
As soon as Bakugo fell I picked up my blazer and walked away from the training grounds,
"R.B, that was amazing!" Cheered Nejire, as she ran up and hugged me from behind.
"Y-Yeah, I didn't t-think you'd have it in y-you." Stammered Tamaki,
"That was an interesting fight!"
Complimented Mirio as I made my way back inside the UA building. "Hey R.B," started Nejire,
"Didn't you break your wrist?"
She asked, as I looked over to her. Her eyes filled with worry, "Yeah, but don't worry about it."
I said, as I started healing myself with my quirk.
"Y-You can heal y-yourself?"
Asked Tamaki, as I nodded my head. "By the way R.B, was that really all natural strength?"
Mirio asked.

Flashback
"Bro, I'm going to get in a fight in an hour, I need the shit." Stressed some random kid, "Yeah, yeah, don't get your panties in a bunch." Another remarked as he brought out a needle, "Hey kid." Said the kid with the needle, pointing to me. "I need you to help me with this." He said, as he handed me the needle, "I need you to hit this kids bicep and then inject him with this." He said, as he started distracting a nearby guard. I hit the boy's bicep 15 times and then injected him. "Thanks kid." He said, as he took the needle and walked off.

Present

Nejire's POV
"Yeah, I don't do steroids." She replied, as she started walking further down the corridor.
"Did k-kids at your o-old quirk c-center use steroids?"
Tamaki asked, in which R.B answered,
"Only when they were going to fight someone." After she answered, my arms wrapped around her torso again and squeezed,
"What's with the sudden hug, darling?"
She asked, making my face blush a bit, "Here there are no kids with steroids, so you can wipe that thought out of your head." I said making her chuckle,
"I'll try, darling."
