|This article is about a/an episode in Samurai Sentai Shinkenger.|
Takeru finds himself under attack by a mysterious power that sneaked into the mansion, while the retainers investigate a strangely suspicious sushi salesman who also broke in.
Returning after what seemed to be a false detection of an Ayakashi attack on the Gap Sensor, the Shinkengers find an arrow with a note on it that says "Coming Soon" with Takeru sensing something from before within the house as it starts to haunt him. Deciding to investigate the Gap Sensor, the vassals encounter a sushi-selling man whose hand writing matches the note. After the seller gives them the slip with spicy sushi, Ryunosuke and Mako go to Shojo Valley to find Takeru while Chiaki and Kotoha track down the sushi seller. By the time they find him, Shinken Blue and Shinken Pink find Shinken Red confronting the Ayakashi Isagitsune who was spying on Takeru to find out the Shiba sealing character. With his mirror medium destroyed, Isagitsune overwhelms the three with his magic as Chiaki and Kotoha coming with the sushi seller following.
But even all five Shinkengers are no match for Isagitsune as they revert to normal as the seller arrives to their aid, transforming into Shinken Gold. After taking out the Nanashi in blinding speed, Shinken Gold battles Isagitsune and destroys him. When Isagitsune revives, he overpowers Tenku-Shinkenoh until Shinken Gold enters the fight in the Ika Origami to weaken the Ayakashi so Tenku-ShinkenOh can land the deathblow. After the fight, Takeru reveals to his vassals that he already knows the sushi seller, Genta Umemori, an old friend of his.
