The novel takes place in April, 2013 and features adult Ryotaro Nogami and Hana. The novel is basically a standard Den-O episode and can work as an extra episode of the series. The novel features the Cat Imagin and the Turkey Imagin (main villain) who made a contract to a dog. At one point of the novel, Momotaros possessed the same dog. Since this is a Den-O novel, the novel is filled with gags and it was implied in one scene that Hana gets drunk with the Taros.
