Training sessions and classes were carrying on in UA as usual-Class 1-A was currently out as training continued. Everything seemed to going by normally. Until something emerged in the air-the air shifted as everyone tenses and before any of them knew it. You had landed onto the ground, Devil trigger activated as you turned to look at the students eith smoke coming out of your mouth as all the power meters broke as soon as uou landed while Aizawa stood infront of them protectively. Belts with an iron grip wrapped around your body just as your Devil trigger deactivated revealing your normal self as you simply just grinned. Aizawa took a step forth, you took one backwards-raising your arms up, you pulled on the scarf and it broke with a snap. Everyone in 1-A looked shocked. No one had ever broke Aizawa's scarf before. So later after much persistence and trouble-you were taken to Nezu's office as Aizawa stood there with Nezu on the table. "What do we do with her? She suddenly came out of nowhere." *Aizawa spoke up, facing Nezu as the mouse's cheerful expression remained, then—something completely unexpected— "She has power even more than Allmight. She will become a teacher at UA high until further notice! Taking Shota's place so he can rest up." Your eye twitched, Aizawa's eyes widened slightly but he didn't say anything. "Hold up, I am not becoming a teacher to babysit a bunch of brats-" You were immediately cut off by Nezu, who started listing benefits of becoming a teacher here at least until you return back to Redgrave.

Noise immediately settled down until Bakugo spoke up. "Tch, we were expecting to see Aizawa-this creature shows up instead? We saw her before! She's not a human, Die!" Bakugo send an explosion straight for your face before Deku could even stop him while the others? They just watched with wide eyes as the explosion hits you right in the face, leaving smoke behind. Only then does Mina speak up. "Bakugo-what the hell, that's our new teacher! Replacing Mr. Aizawa for a month!" Mina exclaimed, arms flailing in panic—Bakugo simply looked away while others just looked at where you stood. Apparently everyone knew about the monthly replacement except for Bakugo. Everyone looked concerned but then—
