At the request of a girl named Rika Fukui and her friends, Daigo builds a T-Rex statue for an upcoming museum exhibit before he meets two of the people he met earlier at the Tiger Boy: Rika's uncle Nobuharu Udo and a rich girl named Amy Yuuzuki. However, a group of Zorima under the Debo Monster Debo Peshango appear with Daigo transforming into Kyoryu Red to fight them before going after Debo Peshango. However, the tearful Sorrowful Knight Aigallon arrives and reluctantly fights Kyoryu Red until Kyoryu Black and Kyoryu Green arrive and teach the newbie how to use his personal weapon, forcing Debo Peshango to fall back while taking his frustration on the T-Rex statue. While placing his Zyudenchi away to be recharged, Daigo meets Kyoryu Pink and Kyoryu Blue with the former revealing herself to be Amy. When Daigo mentions he likes her resolve and that they can fight together, Kyoryu Blue reveals himself as Nobuharu while telling him that he doesn't know how it feels to worry about dragging his family into this. The next day, Nobuharu finds Daigo restoring the wooden sculpture and learns that he went to his Zyudenryu Stegotchi to learn how Rika got attacked by the Zorima before Nobuharu saved his niece. The Deboth Army then resume their attack with Amy finally revealing her fighting skills while instructing the shocked Gentle to take the children to safety. Seeing Rika attempt to protect the statue from Debo Peshango, Nobuharu uses the statue to knock the Debo Monster back while realizing it is his need to protect his family is what makes him strong. With Gentle taking Rika to safety, the three Kyoryugers transform to fight the Zorima before going after Debo Peshango. However, as Aigallon cries over his defeated minion while Kyoryu Black and Kyoryu Green arrive, Canderrilla arrives with Luckyuro using his Sukusuku Joyro to enlarge Debo Peshango. In response, Kyoryu Red summons Gabutyra to fight Debo Peshango while Torin tells Kyoryu Blue and Kyoryu Pink summon Stegotchi and Dricera to combine their Zyudenryu into Kyoryuzin who destroys the Debo Monster. The next day, the dinosaur exhibit ends with Gabutyra posing as Amy and Nobuharu understand Daigo well now.
