While training, Utsusemimaru finds himself in a predicament with the overprotective parents of a spoiled boy named Yuuji. Later finding Yuuji, Utsusemimaru tries to get Yuuji to be independent but finds himself at the boy's mercy. But once taking Yuuji to his house, Utsusemimaru finds the boy replaced by an adorable Debo Monster named Debo Kyawaeen. Finding Aigallon to be behind it, Utsusemimaru transforms yet finds himself unable to fight Debo Kyawaeen before she overwhelms him in her true form. However, as the other Kyoryugers arrive, only Kyoryu Red inflicts damage on Debo Kyawaeen as Aigallon and Luckyuro get her to safety. Taking the tun of events hard as the other Kyoryugers learn that Debo Kyawaeen took other doting parents, Utsusemimaru tries to convince Yuuji to be independent. The next day, Yuuji is captured by Luckyuro and taken to Debo Kyawaeen to be subjected to watching his parents fawn over her. However, expecting this, Utsusemimaru arrives but finds as the parents grab him while Yuuji is knocked down. Utsusemimaru convinces the boy to get back up as Yuuji retrieves the man's Gaburi Changer. Shocking the parents while driving Aigallon and Luckyuro away, Utsusemimaru is joined by the other Kyoryugers as he transforms. Duing the fight, Debo Kyawaeen bewitches Kyoryu Black to fight for him with Kyoryu Pink by subjecting the Zorima to the Stymero Zyudenchi to hold Debo Kyawaeen so Kyoryu Gold can finish all of them off in one hit. With Kyoryu Black returned to normal, Debo Kyawaeen uses the stolen Sukusuku Joyro on herself as she proceeds to fight Pteraiden-Oh before becoming Pteraiden-Oh Bunpachy to finish the Debo Monster off. The next day, Utsusemimaru is visited by a changed Yuuji as he makes his way to school.
