What are you here for? Destruction or peace?

Teaching can have benefits

I wake up to a knock on my door, I get up and I open the door to smell Izuku.

"You ready?" you said as you stepped out of the dorm closing the door behind you.

"I am ready y/n!" Izuku said excitedly. You smile as you lead him to the outside courtyard, on the way you could smell someone else close by but you amused that they were walking in the same direction. Stepping outside you feel the hot cement under your feet as you walk in the middle of the field.

"Ok give me what you got but not too much to hurt you." you said as you got into a fighting stance. You feel something punch you as you feel the wave of force coming from that punch. You didn't budge as you looked at him questioning.

"I want you to feel that power you just used, remember how it felt, the strength you released. I want you to think of it weaker, feel bringing down the power, control is the most important part of peoples quirk. Control can make a hero as none can destroy their body and mind." you said as you walked around the boy in circles. You could hear Izuku muttering to himself as he thought about what you said, talking about how he could cut the percent in half or lower it more. After a minute or two of his mumbling you were about to interrupt him when that strange smell returned but was closer.

You put a hand up to Izuku making him stop mumbling. You wave for him to follow you as you follow the smell. You make a clicking noise to see the smell is emitting from the lockers near the door. You gently grab the handle of the locker and open it carefully trying to not crush it.

"Kacchan?" Izuku said. You get angry as you grab the person roughly and rip them out of the locker. You start growling as you sniff them, you recognized the smell as a student in the 1-A class.

"Oh shit, sorry." you said as you dropped them, hearing them gasp for air as the person puts a hand on their neck a bruise forming.

"You bitch how dare you hurt me, you think I am weak and that I can't defend myself!?" The person shouted angrily. You feel the worry fade away as it's replaced by anger, you are a teacher this person should not be talking to you like that.

"First off boy you were spying on us I had a right to be wary, second you are not supposed to be here after school hours I could get you in a lot of trouble." you said as you could sense the boys anger growing but then changed into fear.

"But I won't, this will be a warning if I sense you nearby after school hours that you don't have permission for I will tell Nezu and get you expelled." you said sternly as Bakugo huffs and struts off. You hear Izuku let out a sigh as you turn to him,"Did you two know each other?" you said.

"Yeah we used to be childhood friends." Izuku said sadly. You didn't like the way he said that but you didn't want to push it.

"Alright let's get back to your training." you said smiling at Izuku.

( Time Skip two months )

Izuku's training has been going splendid, you have been assigned to work with a couple of other students but they didn't stay longer than a week before they ended their sessions, you weren't sure why. You were told that this morning you, some teachers, and the 1-A class will be going out to a dome built for rescue and ways to deal with certain situations. Aizawa brought you to the bus as it then drove off to the dome. You walked to the back of the bus because that's where you can sit without sticking out in the aisle. You were in the bus for at least an hour as it then stopped at what you presumed was the dome. Everyone else gets out of the bus as Aizawa waits for you to help you get off the bus.

"Well I hope you enjoyed sitting back and waiting because this is all watching." Aziawa said as he led you into the dome-like building. The students are all in there as you could hear them talking to each other about how excited they are. You and the other teachers started discussing what lesson should be first when all of a sudden thick metal doors slammed down in front of the entrance locking all the people inside. Aziawa tapped you twice lightly with two fingers, which is a code for you to sense something out of the ordinary. You sniffed the air smelling its reek of sweat and fear. You take in a deep breath as you could smell something different this time, it smelled like decay?
