Mayumi is a woman with mid-back length light brown hair that has bangs hanging over her face, green eyes, crimson-framed glasses and large breasts. She has various types of clothes. However, she sometimes wears only lingerie whenever she's at home. Whenever she is upset or suffering from a hangover, her underwear does not match. Mayumi is a very straight forward person who would always tell a person what comes first on her mind about them. In addition, she doesn't like couples due to her luck with men as she thinks that no one else, relationship wise, should be happy since she's always getting thrown around and dumped by different men.

However, her mood swings that don't stop her from feeling confident about herself when any man/boy sweet talks her.
