After the appearance of Shinken Gold, the vassals learn from Jii that Genta was a childhood friend of Takeru whom he obtained Ika Origami from. Before Takeru could explain why, Genta arrives late to declare himself a samurai under Takeru. As Takeru takes a step out, Genta reveals that he has been training himself for this moment before Jii takes the Sushi Changer from him. As the Shinkengers take their leave upon the Gedoushu making their move, Takeru breaks his friend's heart by refusing to accept him as an ally. After nearly losing to the vengeful Ayakashi Hyakuyappa before he falls back into the Sanzu River, Takeru is confronted by the Vassals and Genta confront Takeru on his reasons for turning Genta before Hyakuyappa resumes his attack. Remembering the promise he made with Genta years ago, Takeru acknowledges his friend as a Shinkenger. While the vassals deal with the Nanashi, Shinken Red and Shinken Gold combine their signature moves to destroy Hyakuyappa. After Hyakuyappa revives, Shinkenoh has a hard time until Ika Origami arrived and combines onto Shinkenoh to form Ika-Shinkenoh who freezes the Ayakashi before destroying him. Soon after the fight, the gang celebrates their newest ally by eating out at the Gold Sushi cart.
