Tsubame is a classmate of Kawakami Momoyo, so she attends class 3-F, as well as one of the new five female heroines introduced in Majikoi S.

Tsubame is a cheerful girl who is a little bit of tsundere. She shares Momoyo's love for battle and because of this, has become good friends with her. She was scouted by Koi Kiriyama, a butler of the Kuki group who was looking for strong people. Tsubame agreed to transfer to Kawakami Academy on the note that her father said that she would face strong opponents there.

Tsubame loves to eat natto to the point where it becomes an obsession as she advertised the natto she loves to eat as well as singing the natto song.

She is introduced as the new member of The Big Four or 4 Devas after defeating the Otome Kan of the East, earning her the title of Tsubame of the East. Due to the fact that she defeated the former third strongest member of the big four, Otome Kan of the East, she became the third strongest without having to have an official match with Yukie Mayuzumi to determine the stronger of the two.

Tsubame can fight with or without a weapon as she has studied different combat styles.
