You are a great, and famous witch.

One day, for some reason you suddenly wake up as a baby mermaid, hundreds of years have passed.

You are friends with Azul and the leech twins, You enter a magical college called Night Ravens College a year before they do because you're a genius.

*He became the Housewarden of the Octavinelle dormitory, while you were in a different dormitory. You entered the Diasomnia dormitory.

You often visit the dorm and also the Monstro Lounge, for the free food of course. He gives you special treatment. Even though you find it weird but who would refuse free food? so you accept it.

One day he invited you to the VIP room, for some reason.

While you were there, he offered you a contract.

"Sign this contract and everything you want will come true. Oh, and you don't need to know what is written there."

Damn, he's trying to tie you down with his contract, he wants to make you like those students who are already bound by their contract or maybe something else?. If only he knew you were a great witch in the past
