A student at Gyoutoku Academy (and later, a member of the Film Studies Club) who participates in Dead Tube's initial iteration as a get-rich-quick scheme. After underestimating the lengths Dead Tube participants have to go through for their payouts, she seeks Machiya's help and eventually befriends him.

Spoiler

Ever since she was raped by her sister's boyfriend as a middle schooler, she's lived the life of a delinquent, relying on all manner of shady activities to keep herself going and easily getting angry. However, after spending some time with Machiya (whom she develops a crush on) and Mai (seemingly being the only person able to snap her back to reality whenever she goes berserk, despite Mai occasionally not being too fond of her), she decides to turn her life around, working part-time as a waitress rather than relying on her usual schemes, as well as growing considerably more composed and compassionate.

Spoiler

In the Rockbar Island game, she's the only one to empathize with Crazy Rascal's situation, correctly assuming that she was on her period and later offering to give herself up in exchange for Rascal's life being spared. This leads to her becoming a sort of bodyguard for Miwa as a token of gratitude, often appearing to shield her from harm and even pairing up with her in the Dead Tube House game.
