Chapter 3: Training

I'm back, @Rumplestiltskin_nofk sorry it took a bit.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
(Y/N)'s POV
I was startled awake by the sound of my new phone's alarm. 'Damn, didn't expect it to be so loud.' I thought as I threw on my school uniform, leaving the red tie behind.
Walking out of my dorm room I hear a familiar voice, "R.B!" Looking over I see Nejire sprinting over to me,
"Hey! No running in the halls!" I hear a tired voice say, making Nejire slow down. "Sorry Mr. Aizawa!" She called out, as she wrapped her arms around me, "Good morning, R.B!"
She cooed making me slightly smile, "Morning to you too darling." I replied as she buried her face into my chest, "Can we get a move on please?"
Asked the tired voice. Nodding I followed the direction where the voice was coming from. Turning the corner I see none other then the greasy hero himself, Eraserhead.
"Took you long enough to wake up." He grumbled, motioning for me to follow him. Turning another corner he started explaining Eri's situation.

After Explaining

Nejire's POV
Turning yet another corner (Y/N) starts seeming confused, "I mean, it makes sense that Monoma couldn't copy her quirk. The quirk is driven by something that Eri has and he doesn't."
"Do you know what that thing is?" He asks, hoping for an answer,
"If I had to guess I'd say the energy is stored inside her horn. But I don't know what it is exactly." Nodding Aizawa Sensei walked out to the training grounds.
Standing right in the center was Eri and Mirio. "G-Goodmorning R.B..." Squeaked Eri, making R.B chuckle, "Morning Kid, morning Mirio."
She said, as Mirio waved. "Alright, I'm gunna be monitoring the entire time."
Stated Eraserhead as Mirio started motioning for me to leave. Nodding I followed him out of the training grounds.

Third person POV
Standing in the center with Eri was now R.B, towering two feet and one inch above the young girl. Kneeling, R.B lowered herself down to Eri's height, "How far have you gotten?" She asked, making the Elementary schooler revert her eyes to the ground.
"I was a-able to completely revert something...that was before they saved me." She answered, making R.B sigh in relief.
"Good, I don't have to bounce around with training then." R.B then stood up and walked over to the main building, "Where are you going?!"
Called Eraserhead, as R.B ignored him and stood right next to a bare wall. Raising her fist, she punched the brick wall.
After the first three times crimson blood started oozing from her skinned knuckle. Four more times added to that and bone started to show.
"R.B! What the hell are you doing?!" Screamed Aizawa, as she continued. Eri starting to tear up at the sight of her trainer harming herself.
Finally after more then 15 times of punching the wall, R.B turned around and made her way back to the center. Holding her bloodied fist in front of Eri, she said just three words,
"Fix my fist." Confused and scared, Eri squeezed her eyes shut,
"Are you crazy?! What if I hurt you?!"
"Calm down."
"What if I can't control it?!"
"Relax."
"What if I do worse...what if I make you disappear too?!"
"Hey!" Eri stopped, standing still as a statue, and just as tense. "Look at me." Said the young woman, making Eri look down more. "I said look at me." Shifting her gaze to (Y/N)'s eyes, she saw pure trust in her (E/C) orbs.
"You can do this. No matter how out of control it could get, it won't be able to. If you do start going overboard I'll move my arm away and fix it myself." Looking down again the petite girl slowly inched her hand closer to R.B's severely injured knuckle. Resting her small hand on her larger one, she started.
Wincing, R.B paid close attention to the feeling in her injured fist. Waiting for the moment where the pain would suddenly disappear, meaning she was healed.
That moment came no more then seconds later when the pain vanished, and was replaced with a calm feeling. Moving her fixed fist away she looked into Eri's red doe-eyes.
The innocent girl with a look of shock and wonder in her eyes. "Did...did I fix you?" She asked, smiling the older girl answered,
"Yes. Yes you did." Just like that, the young girls worried expression was replaced with one of sheer joy. Walking over Aizawa took Eri's hand and turned to R.B, "What you just did was stupid and reckless." He started, making (Y/N) roll her eyes, "But that recklessness made Eri happy. Thank you for this first session."
Nodding, R.B was about to turn away when she felt something wrap around her leg. Looking down, she saw the pale blue-gray haired girl hugging her leg. "Thank you." She muttered, making R.B crack a small smile, "No problem, kid."
With those words Eri let go of her trainer's leg, "Training will take place this weekend as well R.B." "Yes, I know." She answered, before making her way back into the building.

Tamaki's POV
Walking towards the men's bathroom I stumbled across (Y/N), "Hey Tamaki." She called out, "Where are ya heading?"
"T-To the bathroom." I answered, making her chuckle,
"Damn, with your quirk I would have guessed to go off and tentacle fuck some random girl." My face exploded in a red hue,
"W-Why would y-you s-say that?!" "Cause it sounds like something someone would do." She replied, completely unbothered by her reply. "W-we're not l-like the people at t-the q-quirk center."
I stated, making her look at me. She smirked, "Maybe not, but is that a blush I see?" Walking closer to me I tried backing away,
"Aw, is the quiet Tamaki Amajiki intimidated?" Hitting my back against a wall my face was mere inches away from hers.
"N-No." I stuttered, making her back away, "Well alright then. Catch ya later."
She said before walking off into the hallway.
