{Galko's older sister from please tell me, galko-chan}

She is a Japanese college student who is also a model for the gal magazine "GAL AGE" & Gal-themed adult magazines. She is the spitting image of Galko & has achieved tanned skin at a tanning salon.

In contrast to Galko, she has a lot of sexual experience, has boyfriends, & engages in obscene conversations regardless of the situation. The sisters generally get along well, but they often use each other's personal belongings without permission, which can sometimes lead to arguments.

She has a buxom figure, & is perfectly aware of how sexy she is, & loves to flaunt it. She also likes to deliberately get Galko embarrassed as an attempt to desensitize her from sexual topic. As promiscuous as she is, she won't date more than one guy at once, won't mess with men in relationships, unless his partner's cool with it & won't tolerate her boyfriends cheating on her. She regularly sleeps with virgin men, & even describes them as her "favourite food" & is "pretty used to breaking them in."
