Tsubasa Sumisora (澄空 つばさ Sumisora Tsubasa) is the main protagonist in B-Project: Kodou*Ambitious. She is the new A&R hire at Gandara Music, overseeing the idol unit B-Project. She is currently being 'trained' by the company but follows the groups and assists as a usual A&R.


Tsubasa has reddish brown hair tied back into a ponytail with a red ribbon and yellow clips. She has red eyes. She is seen wearing a blue jacket over a white shirt paired with a red skirt and brown boots as well as a black and gold watch on her left wrist.


Tsubasa is shy at first upon meeting the B-Project idols, but becomes a more outgoing person as the series progresses. She's honest, looks for the positive in every situation, and does her best. She has a very keen hearing ability to any type of distinction in music. When asked about how she came to be able to recognize differences in music, she mentions her father but seems a bit saddened by him. Tsubasa is independent and asks questions when needed to and tries to do things by herself but she can also be modest and doubtful of her own abilities in some cases. In episode 12 Yashamaru said that 10 years ago Tsubasa's father killed his family. But Tsubasa didn't know what Yashamaru was talking about.
