Koujaku is a very compassionate and strong-willed Tokota that seems to be fairly kind when meeting new people and Tokos, all except for Mink, Noiz, Trip, and Virus. Although friendly and gentle, Koujaku seems to be harboring large amounts of anger because of other Tokos constantly pestering his closest friend Aoba. Koujaku seems to be a very flirtatious Tokota, even almost on Junhui's level of flirting, and is quite popular with the female Tokos on the ranch, unlike Jun. All together, Koujaku is a fairly kind Toko with a flirtatious side and even some underlying anger.
