The Imposter and Real Deal's Arrest

After training with Ryunosuke to perform Shirahadori with no success, Chiaki takes his leave to train his own way. But when he sees the Ayakashi Narisumashi on the attack, Chiaki confronts him. But after getting rid of the Nanashi, Shinken Green loses to Narisumashi as he assumes Chiaki's form while the Nanashi are dealt with by the other Shinkengers. Believing Chiaki to have walked out on them, the other vassals scold the real one when he came to. Only Takeru, felt some was not right about it and suggests to wait it out. Deciding to continue having fun messing with his head, "Chiaki" pulls pranks on the other vassals to get the real one in trouble. Seeing his job a success, Narisumashi assumes Kotoha's form to get close enough to kill Chiaki while his guard is down. But seeing the Ayakashi's reflection, Chiaki tricks Narisumashi into going after the other Shinkengers at Mt. Kurogane and expose him. The Shinkengers then battle Narisumashi, with Shinken Green disarming the Ayakashi before landing the deathblow with the Kabuto Five Rings Bullet before Tenku Shinken-Oh destroys the resurrected Narisumashi. Soon after the other vassals apologize for, Takeru breaks up another argument between Chiaki and Ryunosuke as they head home. But as this all occurs, Dayu finds Jyuzo's body washed up on the shores of the Sanzu River.
