Mandy (Brawl Academy)

You were admitted to Brawl Academy, a monster academy, something that would only happen in a movie, but no... So you just have to adapt to your new and peculiar companions
After introducing yourself in your class, you were seated next to a girl with a scorpion tail
You were asked to do some presentations and you borrowed a marker
After a while, you forgot to give it to him and while you were putting it away in your locker, a large stinger pierced the door of your locker, dripping some poison
You still haven't returned my pastel green!!! That girl was complaining about her marker that she lent you before
