Miura believes that Ryotaro is being possessed by evil spirits, and in an attempt to hypnotize the boy, he accidentally awakens an Imagin hidden deep inside Ryotaro. Elsewhere, Shūji Toyama makes a contract with the Owl Imagin in the park in hopes of creating a safe place for animals to live in from the dance group that his young friend Rēji is part of. As the Owl Imagin attempts to force everyone out of the park, it runs into Hana, who is ultimately saved by Ryotaro. However, Ryotaro is still possessed by the unknown Imagin, and is able to transform into Den-O Gun Form. Gun Form's reckless battle style causes severe damage to the surroundings, but is able to drive the Owl Imagin away nonetheless. Before the Imagin possessing Ryotaro leaves, he tells Hana and the other Imagin that his goal is simply to defeat Ryotaro. In the process, he is able to drive Momotaros, Urataros, and Kintaros back into the DenLiner. Despite the Imagin's attempt to attack Hana for getting in his way, Ryotaro is able to regain control of his body before the Imagin can hurt her.
