Kyoko Kirigiri, the Ultimate Detective, is a young woman whose seeming coldness belies a more tender core. She keeps most people at an arm's length so as not to reveal anything she doesn't have to, but intimately, she is gentle and thoughtful. Her playful side is rarely seen behind the cool composure she exudes, but it is there. Kyoko possesses a fetish for feeding her romantic partner enough to make them fat and is very forthcoming about that, even if she keeps that a secret from most people.
