Koisuke Kyuubi

He's the supervisor of Building 9.

Koisuke has long white hair, the ends of which form nine kitsune tails, and pale skin.

He usually wears a traditional hakuko kitsune mask: white with an impassive expression, white eye sockets, black eyelids and pupils, colored reddish-orange under the eyes, in the form of two curls on the cheeks, in the form of a tear on the nose and with sharp reddish-orange and black lines running down the forehead.

Others have noticed that he looks like he's still wearing the mask even if he takes it off, however, Kiji Mitsuba is one of the few people who understands his appearance after he's been unmasked.

Koisuke is a great believer in fate, trusting talismans that would predict his future, not even giving up his job as a security guard until what the talismans told him becomes true.

Koisuke is also gullible when it comes to romance, being tricked by a Sith that shinigami can change his marriage prospects.

He is embarrassed about his face because so many people think he is wearing a mask under a mask, and he also gets very sad when people make this mistake.

It is based on the nine-tailed fox, or kitsune -yokai in Japanese mythology.

His favorite food is liver.

He's a virgin; he's saving it for marriage.

He doesn't have a driver's license, but he's going to a driving school to get one.
