In Otarangers' uniform, he wears his sentai-colored tracksuit while donning a handmade ranger helmet with an X-visor, beak-like mouthguard and owl-winged ears.
Ota Blue is the second-in-command of the Ota Rangers, but at times he gets disrespected and ignored by his fellow teammates. That being said, he has a strong sense of justice only rivaled by his team leader. Like the other members of his team, he has a quirky fanaticism: celebrities.
After the events of the Fairy Tale Project, the rest of the Ota Rangers minus Ota Red started vanishing as he was developing a new Hissatsu Function, where he requests help in searching for them. He eventually finds them ignoring training at Akihabara Hall. Ota Blue gets outraged, and challenges his teammates to a battle. With help from Ban, Ota Blue won the battle and Ota Pink, Yellow, and Black apologized for their actions. In turn, he admitted that he overreacted too much. The four regain their friendship.
- Ota Blue's design comes from the Super Sentai inspiration, as the Blue Ranger sub-leader type.
- Prior to his identity, his color theme is blue.
