Originally born on Earth, Mayumi grew up like any other young girl. When she was old enough, her and her parents moved to Zeta-C, a space colony in orbit around mars that was well known for a very unique culture where huge boobs were the norm. She is currently interning at a publication and media company while finishing school and adapting to a new lifestyle.

Mayumi was always a good girl and she's really a sweetheart, but........... she's a bit sex crazed in an innocent clueless way. This worked to her advantage when arriving to Zeta-C as the nudity and revealing fashion didn't bother her much. She's honest, super friendly, studious, and a bit of a kluts. But even in her clumsiness she's still adorable.

Trendy but comfortable even if barely covered. Zeta-C fashion more often makes clothes more of a compliment than a means to cover.
