Personality
Kokuyō is a very serious and straightforward individual. He shows little trust in others and focuses solely on his mission. He is shown to be very merciless, willing to kill allies to insure no loose ends should they fall behind. At the same time, he views it as mercy killing, letting them die with dignity.

Mitsuki's Disappearance Arc
Kokuyō first appears attacking Saō and Uō at the entrance to Konohagakure alongside Sekiei, leaving both men in comas before leaving with Mitsuki. On their way back to the Land of Stone, Sekiei took an open liking towards Mitsuki as an artificial human. He began talking about how Mitsuki's being would help in advancing their goal, only to be interrupted by Kokuyō, who didn't trust Mitsuki with such information. As they approached the Land of Earth's boarder, Kokuyō noticed that they were being pursued by Konoha-nin. Sekiei was sent ahead with Mitsuki while Kokuyō engaged the pursuers. He quickly dispatched the jōnin, and then met a group of Konoha genin who were unofficially pursuing Mitsuki.
