Kin is the captain of the idol group 'Octeez'. He is feral on stage, however it is all an act (...mostly), he is actually pretty quiet and reserved off stage. ALthough he can be strict with them, he cares deeply about his members, would do anything for them, as they would for him. He is closest with Hitode, who he shares a room with. Almost always has his tongue out, a side effect of being sanitised.

He was once a high ranking elite octoling soldier. Kin formed Octeez while underground, the group consists of octolings he became close friends with during training. They all vowed to escape to the surface together. However Kin was selected to be sanitised due to his rising defiance of the system. He was completely sanitised and therefore lost his memory but was rescued by his group who over time helped him to regain most of his memories. They all escaped to the surface and became an idol group.
