She has influence with the police and has conducted thorough groundwork to ensure no interference with the game. Secretly, she looks down on the samurai as "ugly ghosts clinging to an outdated privileged class, left behind by the times." Her catchphrase is, "Well then, have a pleasant journey."

26 years old, male. Enju's right-hand man. Among the guards armed with guns, he is the only one who carries a sword, serving as the elite unit commander.
