Hunt for Kamui's secret

Kakashi tried to defeat him alone because Chiro and Ikebana refused to fight against their friend, but after seeing that it was impossible Kakashi win the uncontrolled Keshigomu, Chiru went into battle and was soon followed by Ikebana. In the end, Keshigomu regained his sanity, but it was late and he was condemned to die because of a forbidden technique he had used. As a last breath, Keshigomu tried to sacrifice himself by throwing himself into a river and asking Kakashi to defeat him with his Kamui. However, shortly before Kakashi complete the technique, Keshigomu hit Ikebana unwittingly, which left her comatose.

After the battle, Chiru apologized with Kakashi and asked him to call help to hospitalize Ikebana.
