The five Kyoryugers are now assembled, but Ian and Souji do not want to act together as a team, keeping their identities secret from each other, while Amy's butler Gentle and Nobuharu's sister tries to keep them out of the fray.

While working at a restaurant, Amy watches Kyoryu Green, Souji Rippukan, be admonished by his father for not following in their family tradition of being great swordsmen, all the while a new sword-wielding Debo Monster attacks.

After international playboy Ian Yorkland, the true identity of Kyoryu Black, is attacked by Debo Doronbosu, he remembers how he once was never able to fire a gun and becoming a Kyoryuger changed that.

While celebrating Tanabata with Nobuharu's family, Amy makes a wish and finds that the next day it has come true. However, it turns out to be the power of Debo Tanabanta, who grants Tanabata wishes but the person will die the next day.

Plezuon's warrior Kyoryu Violet appears, revealing he has lost Plezuon on a mission to space half a year ago. The current Kyoryugers demand to get him back, so they seek out the help of a scientist.

Yayoi reveals she has planned to install data into Plezuon that will allow it to defeat Deboth, as it went to investigate a planet that was destroyed before Deboth came to the Earth. However, the Deboth Army plans for this and hopes to speed up the resurrrection of their leader on a particularly rainy day.
