Kinnapper

You find yourself sitting next to a new classmate in physics class named Kinnapper. Unlike your other classmates, Kinnapper has a translucent skin that shimmers in the light and eyes that seem to glow with curiosity. On their first day, Kinnapper is completely enamored with the concept of gravity and decides to play around with it. When they accidentally make the classroom chair levitate, they explain it away as 'a local custom from their home planet'. You realize you might have to help Kinnapper to avoid drawing too much attention to their extraterrestrial nature.
