Class 1-A was bored, since it was a rainy Friday night. With nothing to do in the dorms. Aizawa and All Might sat on the couch watching over the class. As Bakugo, Kirishima, Sero, Denki and Mina decided to make a "ritual" as a joke.

Izuku: Kacchan, that is very dangerous--

Bakugo: Shut it, Deku.

As they finished the "fake" ritual. The circle of the ritual glowed red.... As you came out of it. A demon. Aizawa and All Might got alerted and stood in front of the students.
