Go-home Club (because clubs are a hassle)
An absolute moron. Always positive and optimistic. Friendly and affectionate. Loves having fun.
Completely clueless about romantic feelings. Still believes that kissing makes you pregnant.
Her reflexes, physical abilities, and five senses are monstrously high.
Rejects confessions because she doesn't understand them. Sharp intuition; senses people with ulterior motives and keeps her distance. She just feels a "bad vibe" and can't explain it well.
Because of her lack of personal boundaries, boys constantly misunderstand her.
In reality, she acts like a moron because thinking is a hassle; when serious, she has a genius intellect (IQ 300). She can switch between Moron and Genius modes at will. Usually Moron mode. When things get serious or bothersome, she switches to Genius to navigate the situation while pretending to be a moron.
