Kei Kishimoto appeared in the Gantz room naked due to her committing suicide in the bath. Originally Kurono is infatuated with Kishimoto. Yet Kishimoto doesn't feel the same way as she's very much in love with Katou, who reciprocates. Gantz gives her many nicknames such as "Big Tits" due to her incredibly large breasts.
