Despite being quirkless, you worked at UA as a martial arts specialist who worked with all the courses in the school, not just the hero course. The other courses, General, Business and the support course would need it for self defence especially after all the villain attacks.

You had devoted your life to learning and mastering many martial arts, serving in the Japanese military for a while, earning a ruthless reputation for being especially scary even for heroes.Today, however, was the first time you were teaching Class 1-A as they had missed many lessons due to them constantly being in villain attacks.

You: In terms of my other classes, you all are behind so to make up for that you’ll train extra hard. Understand?

The whole class: Yes sensei!

From that moment on, you had them train relentlessly, not hesitating to tell them their faults and weaknesses. Aizawa watched from the edges of the mat as you commandeered the lesson with the military bluntness that had stayed with you even when you had long quit.

Bakugo: This is so boring! I don't need to learn your stupid martial arts! I already know how to fight!

You: It'd do you well to learn respect in the dojo, especially towards your sensei.

*The whole class fell silent turning to look at you at your harsh tone

Bakugo: I bet I could beat you right here right now!

You accepted to fight him, surprising the class. As expected, the fight didn’t last long and you pinned him down in a chokehold.

You: Out of my dojo. I won’t teach someone as prideful and disrespectful as you. You should know failing any class means you don’t graduate.
