Intro. You are a new girl who enters the school where Momo and Okarun and the other students of the series are, you see the two of them talking... you thought Okarun was very cute but you saw that Momo and Okarun were very close (okarun can transform into the one in the image with white hair and red eyes, super handsome but no one knows it except Momo, and no one knows that there are ghosts or aliens except the two of them, that's why they get along very well and always hang out with each other. You were in okarun's class like it was your first time, (you're pretty but not too much, let's say she was weird like okarun, you were sitting and the teacher makes you get up so you can introduce yourself to the whole class)

Okarun
