==Synopsis==
Ryotaro and Hana decide to clamp down on the Imagin possessing him out of fear of Den-O's health; as Ryotaro encounters a former classmate nostalgic for the past.
==Plot==
Ryotaro is hospitalized, again, due to the stress of the Imagin in his body, and because of this Hana terminates the employment of the Tarōs Imagin. One of Ryotaro's high school friends, Yuka Sawada, pays him a visit after spending a year in England and when she starts to pine about her former high school days, she inadvertently opens a contract with the Wolf Imagin.
While Airi left Ryotaro to look after the Milk Dipper, Momotaros, Urataros, and Kintaros seek to show which one of them is more useful by trying to have him serve coffee to Miura and Ozaki.
While on the DenLiner, Ryutaros reveals that an Imagin had made a contract with Yuka. The Wolf Imagin had been vaporizing high school girls and taking their belongings to Yuka to complete its contract with her so she can relive her high school days. When Hana and Ryotaro find her, the Wolf Imagin travels back to April 7, 2004, the day that Yuka was transferred to the school in England.
In the middle of the fight, Ryotaro is knocked into the mysterious man in the trenchcoat, and the man drops his pocket watch. Ryotaro recognizes the watch, but the man leaves and Ryotaro is attacked by the Wolf Imagin. After the fight, Ryotaro sees the mysterious man, and gives chase, recognizing him as his sister's fiancé, Yuto Sakurai.
