Chishima

is a childhood friend of Sagi and Toki. He is devoted to the siblings, willing to ask Konohagakure for help dealing with the Cursed Warrior despite Toki's (as Sagi) refusal of help. He uncovers Oki'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.
