Chishima

A friend of Sagi and Toki. He is devoted to the siblings, willing to ask Konoha for help dealing with the ghost despite Toki (as Sagi)'s refusal of help. He uncovers Mousou's deception, and while he is nearly killed in the process, reports the finding to Toki and Naruto. He is almost killed by one of Oki's attacks, but survives.
