One of Genta's best customers, the wealthy Yoshihisa Matsumiya, asks him for a favor; he asks if Genta can convince Kotoha, who Matsumiya had met once before, to masquerade as Matsumiya's fiancée at a high society party. Not only does Kotoha agree, but Takeru also agrees to pose as her butler. Meanwhile, the Ayakashi Urawadachi appears, looking for a "sweet" life to consume. Ryunosuke alerts Takeru, who leaves the party abruptly with Kotoha and Genta to join their teammates and engage Urawadachi, who summons the Nanashi to keep the Shinkengers occupied as he retreats. Takeru still senses the Ayakashi's presence as he and Kotoha, still keeping up the charade, leave for her dinner with Matsumiya. Smitten with Kotoha's kindness and pure heart, Matsumiya is about to confess his feelings when Urawadachi is revealed to be hiding in his jacket. The Ayakashi begins to suck the life out of him, declaring that the only way to free Matsumiya is to kill him. Thinking quickly, Kotoha pretends to be extremely shallow, making sure that Matsumiya hears and sees her slapping and berating Takeru, who quickly catches on to Kotoha's ruse and plays along. Matsumiya is heartbroken, severing Urawadachi's hold on him. The other Shinkengers arrive to offer assistance, and Shinken Yellow takes down Urawadachi before he is destroyed with the Tora Five Rings Bullet. While Tenku-Shinkenoh deals with the ?zorananashi, the Ebi Origami and Ika Origami combine into Ika-Daikaioh to destroy Urawadachi's second life. After the fight, Matsumiya thanks Kotoha for saving his life and, seeing that she cares deeply for Takeru, parts ways with her amicably.
