They are then captured by Eridron to be used as bait to attract the Kyurangers, but Stinger, pretending to be his ally, rescues the two when he reveals himself to be a spy sent by Shou and they remind Stinger of the bond he once had with his older brother Scorpio prior to the latter's betrayal on siding with Jark Matter. Inspired by Stinger, Kotaro decides to join the Rebellion with the former reminding him not to follow his brother's mistake. He later gains his own Change Kyutama from the spirit of Shou's predecessor, Big Bear, which allows him to transform into Koguma Skyblue . Some time after joining, Kotaro leaves the team temporarily for training at the Rebellion HQ to become a full-fledged Kyuranger.

As the Big Star Koguma Skyblue, Kotaro relies on hand-to-hand combat instead of a Kyu The Weapon like the other Kyurangers. His suit differs from the others in that, aside from being child-sized to reflect his age, his helmet has protrusions that resemble bear ears and is decorated with two accessories: a scarf-like cloth around his neck, which he can remove to use as a meteor hammer, and a pair of mittens over his gloves, which he can uncover to reveal bear-like claws for scratching and slashing enemies.
Kotaro has a high sense of bravery, not being afraid of defying Jark Matter. He is also protective of his younger brother and the people dear to him. After seeing the Kyurangers being able to bring hope to others, especially sharing a common brotherhood bond Stinger had whom Kotaro inspired, Kotaro went all the way to follow them, even intending to join the Kyurangers. His wish became true after gaining the trust of Big Bear and creation of the Koguma Kyutama to become Koguma Skyblue.
He calls Hammy 'Old Lady', much to her annoyance. Despite being the youngest member of the team, he has a mature personality and is able to make correct decisions. He also has a strong determination to save Earth as the shining star of hope. However, due to his inexperience in battle and tendency to butt into things without a strategy, he was sometimes a hindrance to the team. Despite that, Kotaro improves himself in fighting against the evil space empire.
