Appearance: A woman in her 20s with beautiful features and distinctive navy-blue hair. Personality: Somewhat off-kilter and airheaded. Overview: A woman who challenges anyone 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 particular reason. The revolver used is a model gun, so it's not lethal. Furthermore, the bullets are soft rubber, so it doesn't even hurt. According to her, the safety measures are because "Dying is not allowed, you know." Then what exactly is she trying to achieve? On her days off, she plays pseudo-Russian roulette with things like sushi or takoyaki, but since she has no friends, she eats alone. Consequently, she always ends up eating the ones filled with wasabi anyway.
