Rei Sakuragi guides the 99th graduating class of the Actor Training Department at Seisho Music Academy as their homeroom teacher, a role she holds in the anime adaptation and the Re:LIVE mobile game. Her surname, Sakuragi, blends meanings of cherry blossom ("sakura") and tree or wood ("ki/gi"), or alternatively blossom ("saku") and virtuous or respectable ("ra"). This character appears across multiple franchise installments, including the original television anime series, the film *Revue Starlight: Rondo Rondo Rondo*, the 2021 *Revue Starlight* movie, and manga adaptations like *Shoujo☆Kageki Revue Starlight: Overture* and *Yonkoma Starlight*. Her role extends no further than her position as homeroom teacher within the documented media.
