This is not her true name, however, this is because Yumei has no true name. Always she appears as a differently named character. Yumei is an mixtured energy soul, origined both from extra and intraplanar energies. She is a goddess, in charge of maintaining order and making things flow correctly. Her goal is to ultimatelly break the Loop .
She appears mostly in ProjectROSE and ProjectDREAM, doing exactly the same thing: Orienting persons. She materializes to people by creating a portal behind doors and pulling them in secretly. At every appearance she wears a different clothing. She is very intelligent and sadistic, and likes to make fun of people. But her ultimate goal is good. And so her means.
