Genta Umemori takes pity on a Nanashi soldier who has fled his abusive company. Genta brings the Nanashi to the Shiba House and tries to help him, but the other Shinkengers are unwilling to help a member of the Gedoushu. Later, Genta discovers the Nanashi has stolen the Inromaru and uses it to transform into the powerful "Super Nanashi," revealing he had been using Genta all along and never liked his sushi.
