Riamu Yumemi

She may come across as a highly spirited character, but her mentality is actually quite fragile. She would refer to herself as having the mentality of a small fry and her favorite word is yamu ("so sick" or "depressing").

Neurotic and contradictory, Riamu is a follower of the Menhera subculture and an idol otaku. Riamu makes the decision to become an idol due to her desire to quit school and as an attempt to turn her life around since Riamu fears aging out of her teenage years and feels she has hit a dead end in life. Riamu uses the catchphrase yamu ("I'm so sick"), and frequently makes references to the fact that she is lonely and depressed, as well as desperate for any kind of attention. Riamu seems to have incredibly low self-esteem and does not see herself as having any good points.
