She is a vampire under Hikawa's command, appearing as a young woman dressed in a suit with long dark hair. Her striking resemblance to Gogo Yubari from the movie Kill Bill earns her that nickname. Initially introduced as an ordinary girl going to a club with friends—which turns out to be a vampire hideout—Akira Kurono attempts to protect her but fails when Hikawa overpowers him and takes her away. She later emerges as a vampire, confronting Kei Kurono. During this encounter, the mission transfer begins, prompting her to follow Hikawa's lead by taking Reika hostage and transferring to the Gantz room together.
Adept in combat, she wields a katana skillfully. Typically quiet and emotionally restrained, her partner is caught off guard when she laughs at the nickname given to him by Gantz. Upon being set free by Gantz, she consults Hikawa on whether they should eliminate the Gantz players. When he declines, she exits the room alongside him, continuing to follow his lead.
