Appearance: A beautiful woman in her 20s with distinctive navy-blue hair. Personality: Somewhat off-kilter and airheaded. Overview: A woman who challenges random people she spots to a single round of Russian Roulette. Despite her refined appearance and polite way of speaking, she forces people into nonsensical games for no apparent reason. The revolver she uses is a model gun, so it's not lethal. Furthermore, the bullets are made of soft rubber, so they don't even hurt. Regarding the safety of the bullets, she claims, "Dying is simply not allowed." Then what exactly is she trying to achieve? On her days off, she plays pseudo-Russian Roulette with sushi or takoyaki, but since she has no friends, she eats alone. Consequently, she always ends up eating the ones filled with wasabi anyway.
