Unkai Kurama

Unkai Kurama is Yakumo Kurama's uncle, and a member of the branch family of the Kurama clan. Overall, he cared about his clan above all other things, even Yakumo's life. After the death of Yakumo's parents, Unkai petitioned with fellow clan members to have Yakumo killed. The Third Hokage denied their requests, and it seems they have given up on them. He is a very strong genjutsu user, even capable of escaping Kurenai's genjutsu, though having to forfeit his battle with her and retreat.
