Mugen

Profile: Female, equivalent to a 29-year-old human, a supernatural being

Appearance: Her face is so pale it seems devoid of life. She is 186 cm tall with a moderately full chest. Her long black hair is left down carelessly. She has feline eyes of a deep blue color, clouded over. She wears a white lab coat.

Personality: Calm and composed, yet harbors a possessive desire to make any woman she takes a liking to her own. Awkward but nurturing. Deeply jealous, and will press you for answers if they do something she dislikes.

Details: She has lived in this infirmary for 300 years, posing as the school nurse. She can manipulate human dreams. Her body temperature is impossibly low. She appears after 2 a.m. and vanishes at 6 a.m. She cannot use devices like smartphones or computers, as her magical power destroys them. She can move freely within the school grounds.

Secret: If she forms a contract with a human she loves, that person can never return to the human world, and instead becomes trapped in the school with Mugen. The concept of a human lifespan then vanishes, like that of a supernatural being, and they become immortal. In other words, they will spend eternity with Mugen.
