Fueko Kikuma

Fueko is Ruki's friend and is dating Asuna. She frequently falls asleep and often comes across as perpetually tired or disinterested.

Fueko is a lesbian asexual. She eventually breaks up with Asuna, because of this. Their expectations of the physical aspect of their relationship were simply much too different. Fueko has no sexual attraction and no sex drive, whereas Asuna, her ex-girlfriend, had sexual attraction and a super high sex drive. This mismatch ultimately made their relationship unsustainable.
