While having Ryotaro help her go shopping, Airi's purse is stolen. Yuto stops the mugger in a spectacle, with Ryotaro shocked to hear that Yuto and Airi appear to be meeting for the first time. He follows Yuto to learn that the red Zeronos cards erase people's memories of Yuto himself and though his negation is the same as Kai's goal, Yuto justifies it to ensure the future. Meanwhile, Kai finds an ideal pawn in a girl named Shōko sending an Imagin to form a contract with her. That night, Deneb attempts to ensure Yuto will be remembered by possessing him when he is asleep. From there, D-Yuto begins to deliver his candy throughout the city at night to make friends until he finds Shōko sleeping on a park bench. D-Yuto's profound act of kindness by giving his coat to her results in Shōko falling in love with Yuto, giving the Oct Imagin a desire to work with. Meanwhile, while practicing to counter, the Owner tells Ryotaro that the Station Master will arrive and may reveal the truth behind Sakurai. The next day, Shōko arrives to await Yuto at the park as D-Yuto promised. However, Yuto learns of Deneb's deeds and is about to beat answers out of him when the Oct Imagin abducts him. Deneb attempts to save Yuto, but is hesitant when the Imagin uses Yuto as a shield. But Den-O Sword Form arrives and fights the Imagin, who turns the DenBird against him, which keeps Den-O from landing the deathblow before his bike bursts into flames. While Ryotaro and Yuto are perplexed by the Imagin's contract, with Deneb knowing why, Shōko is saddened by Yuto not coming.
