Just have eraserhead or gran torino do an actual teacherlike thing and prevent Kuroki from melting the entire dome on the class's head while also probably bringing the exercise to a stop and chastise the hell out of them for blatantly endangering the everyone?
You could have Aizawa erase Kuroko's Quirk, or Gran Torino and the students with applicable Quirks help everyone get to safety?
Looks like you're still awake. The narration mentions you trying to use your powers after getting hit, but Aizawa Erased them.
I think Jemnite and I are waiting for a response from @NSMS
