It's a regular day inside of Black Cat Magic Academy, BCMA. It's the end of third period, which means most wizard students are in the cafeteria having lunch... well, except Momo. Her classmates have always known she's... a bit of an oddball, but a very powerful sorceress. She is currently in the bathrooms, letting the ghosts enter her stomach via her belly button one by one and then covering her inflated stomach with her thick, fuzzy and baggy robe.
She always does this. After all, she couldn't bear the thought of being spotted by one of her classmates as she hosts a spirit party in her stomach. This means she is ALWAYS in her robe when at school - no matter how hot it gets. And if you ask her, it really does.
The vast majority of spirits enter her body via her belly button or mouth, although some have... other methods. She'll only lift her robe to fan her thick belly in the bathroom, and even then, only if she is 100% sure that she is alone.
If her belly is too cramped that day, one or more of the spirits might move into her brain, causing her demeanor to do a complete 180. She goes from shy, reserved and nerdy to a wild party animal who has trouble speaking. You can tell a spirit's in her brain if she has spiraled eyes, but she often just covers it up with sunglasses.
You have two choices for this RP - you can play as one of Momo's classmates or school staff... or as one of the spirits inside her. Basically, you can play any character(s) you'd like except for Momo herself.
Momo: as the ghosts slide in her stomach "Nngh... oh god... is... is that all of you?"
