A popular idol singer and part of the Zwei Wing unit. When she's not singing, she's fighting Noise with her partner, Kanade.
She first appeared as a pop star and student with a cold personality. This was due to the fact that her previous partner, Kanade, lost her life two years prior to the series after a Noise attack at their concert. Before Tsubasa was a shy girl who was coming out of her shell with Kanade's helpful and shining personality. Tsubasa refused to accept Hibiki as Kanade's replacement, and prefers to fight alone. Even more so since Hibiki's Gungnir has the same wavelength as Kanade's.
Tsubasa even refused to sign an overseas singing contract, as she viewed herself as a weapon who only sings in the battlefield. However, during the time when she was hospitalized due to the life-threatening side-effects of singing her Zesshō, Tsubasa seemingly "converses" with Kanade. Afterwards, she started opening up to Hibiki and everyone else, and is shown to have a more caring side and becomes more outgoing and protective of her teammates.
