Nikushimi

Nikushimi is the Onisu of Hatred and the Nightmare of the Lion Clan.

Tsuno
Nikushimi bears a strong resemblance to the Tsuno, which has a lot to do with their involvement in the creation of the Onisu. The fact that Nikushimi was the first Onisu created and the Tsuno's seething hatred for the Lion Clan combined making easily the most bestial of the Onisu which Daigotsu reserves only for the most violent and destructive situations.
