On the eve of Tanabata, the Kyoryugers spend time with Nobuharu's family. Amy wishes to pass her upcoming German exam, Souji wishes for a new bokken, Utsusemimaru wishes for a lot of frozen treats, Ian wishes to find the fossilized remains of an undiscovered species, but Nobuharu keeps his wish a secret. Only Daigo has nothing to wish for on a slip of Tanabata paper, but there is one thing he wants. The next day, strange things happen when peoples' Tanabata wishes come true, and then they collapse. Following the path of people, the Kyoryugers encounter the Debo Monster Debo Tanabanta. With Canderrilla and Luckyuro arriving to join Tanabanta, they reveal it is he who has been granting the wishes. However, as seen with Ian, Souji, and Amy, those who have their wishes granted start to weaken and eventually die the next day. Debo Tanabanta reveals that the bamboo tube on his chest contains the joy energy he has amassed before leaving the Kyoryugers behind. Later, though thinking he will be safe from Tanabanta in the Spirit Base, Utusemimaru gets his Tanabata wish granted when Kyoryu Cyan makes a visit with a box of frozen treats he got while searching for Bragigas in Belgium. Nobuharu also gets his wish to get his hands on ladies fulfilled when he unknowingly allows Rika's teacher and her peers to hold his hands in gratitude. Upon finding Debo Tanabanta using Nobuharu's Tanabata wish paper, Daigo finds himself outmatched by him, Canderrilla, and Luckyuro before the Debo Monster runs off. Daigo chasing after Debo Tanabanta as the sun rises, and when he finds the monster, he sees his father punching Debo Tanabanta to destroy his bamboo tube. With their lives restored, the Kyoryugers find Daigo as his father tells him to continue down the path he chosen. Happy that the wish he made on a star on Tanabata came true, Daigo and the others transform to defeat Debo Tanabanta with the Kentrospiker. Then, with Pteragordon backing them up, Kyoryuzin Kung-Fu destroys Debo Tanabanta and his Giant Zorima backup. Back at the Spirit Base, the gang talk about Daigo's good mood as Torin returns with a bag looking like the one his father had when he saw the fight with Debo Tanabanta.
