With the mysterious Imagin, who names himself Ryutaros, now one of the Imagin with connections to Ryotaro, he sets his sights on destroying Ryotaro to become the conductor of the DenLiner. Momotaros, Urataros, and Kintaros put aside their differences try to get rid of him, but with a ticket to the DenLiner, this is impossible. Meanwhile, Hana tries to find the Owl Imagin and its contract holder, as the Owl Imagin continues to make it so no human may enter the park. It is not until Ryutaros is distracted by some stray animals that allows for Momotaros to regain control of Ryotaro in order to go back in time to February 20, 1997, and prevent the Owl Imagin from destroying the past. However, in the middle of the fight, Ryutaros repossesses Ryotaro and Gun Form is the one to finish off the Owl Imagin. When the Owl Imagin goes berserk and splits into Gigandeaths Heaven and Hades, it takes both Gun Form's Wild Shot and the DenLiner Ikazuchi to defeat them.
