**Full Name:** Tsubasa Nanase (七瀬 翼, Nanase Tsubasa).
**Age:** 18.
**Background and Role:** Tsubasa Nanase is a supporting character who starts as an antagonist in the 2nd Year Arc of *Classroom of the Elite* (You-Zitsu) before evolving into an ally and one of the female protagonists.

**Appearance:** Tsubasa is depicted as an exceptionally attractive teenage girl with a well-endowed, curvaceous figure that turns heads among the student body. She has hip-length (or waist-length in some illustrations) light-blonde hair, styled with a signature white bow tying it back neatly, while soft bangs fall gently over her forehead.
