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.

In the first season of the anime, she wears a blue jacket over a white shirt paired with a red skirt, brown laced up boots with blue socks, as well as a black and gold watch on her left wrist and a necklace. Her outfit later changes to a black jacket (similar to her blue jacket) over a white blouse with a green vest, paired with a red skirt, tall brown boots and a gold necklace. She wears a large pink coat to accompany her second outfit.

In the second season of the anime, she wears a pink jacket over a white turtleneck paired with a turquiose skirt with a white belt, tall brown boots and a gold necklace. She wears a large vermilion coat with a hood to accompany this outfit.


Tsubasa is shy at first upon meeting the B-Project idols, but becomes a more outgoing person as the series progresses. She has an honest personality, and does her best to remain positive in every situation. Tsubasa is also independent, though she asks questions when needed to and she tries to do things by herself. However, she can be modest and doubtful of her own abilities in certain cases.

Trivia Edit

  • She has a very keen hearing ability to any type of distinction in music, which has been demonstrated in the first and third episodes of the anime's first season. When she was asked about how she came to be able to recognize differences in music, she mentions her father but seems a bit saddened by him.
  • In the final episode of the first season, Yashamaru said that Tsubasa's father "killed" his family ten years ago. However, Tsubasa didn't know what he was talking about.
  • The voice actress of Tsubasa, Hisako Kanemoto announced that she would be going on hiatus to study abroad until March 2019. She was replaced by Asami Seto, who voiced Tsubasa for the anime's second season.
