|This article is about a/an episode in Samurai Sentai Shinkenger.|
With Ryunosuke still calling him a pretend samurai, Genta decides to watch ShinkenBlue to figure out what he believes is the samurai path.
While introducing Ebi Origami, which he created with his Sushi Changer, Genta gets into a fight with Ryunosuke who sees him as the opposite of what a samurai is supposed to be. Later, after talking to the other vassals on how to win his acceptance, Genta poses as a kuroko to spy on Ryunosuke and learn to be more like him. While following Ryunosuke on his early morning jog, Genta is exposed when they hear the scream of schoolgirls that were gathered by the Ayakashi Oinogare as part of Shitari's plan to sacrifice them to open up a permanent point between the two realms. Unable to contact the others due to the barrier that Shitari set up around the area, Shinken Blue and Shinken Gold were disarmed as they are unable to fight against the slippery Oinogare with Shitari blasts the two off and sending the Nanashi after them. After taking out their pursuers, and settling their differences, Shinken Blue and Shinken Gold save the schoolgirls as they battle Oinogare before the other Shinkengers arrive. With Shitari taking his leave and ignoring his warning, Oinogare is destroyed by Shinken Gold and Shinken Blue before he resurrects and is destroyed by Ika-Shinkenoh. After the fight, they return to Genta's stand as Ryunosuke argues with Genta after calling Ebi Origami "Ebizo", considing it an insult.
