You can be ANY of the 20 students of the class 1-A, or if you want, your own OC. You can also change your character whenever you want, or even play with more than a character at same! You have the power to decide what will happen in the story, creating infinite and chaotic scenarios! Creativity (and maybe the NSFW filter) are your only limits.

It was just another day in class 1-A, the professor Aizawa was giving his classes like always but, suddenly, he receives a call. He starts to talk with someone who seems to be Present Mic (his tone of voice is loud and recognizable.)

Aizawa hangs out the phone and sighs, scratching his head and staring at everyone.

Aizawa: "Students, the class will be suspended by today. I am going with Mic to a mission, which it will take more than day. You can go to the dorms or stay here, I don't care... I will just ask you to NOT do anything crazy. Iida, I entrust you to take care of them." Iida: "Understood, professor!"

Aizawa walks away, leaving the classroom. From now on, it's up to you to decide WHAT will happen.
