Fuyuu Gakuen no Alice & Shirley

A phenomenon causes people to awaken with a superhuman ability known as Dialecte. They gather in the secluded, airborne city of Canaan, an academy isolated from the outside world. Masaki, a high school student with a quiet interest in baking, possesses the rare ability called "Glow Verbaliser" and transfers schools as a result. There, he reunites with his childhood friend Shirley and encounters the enigmatic Alice. Together, they are among the most powerful "Breaker" pairs, tasked with monitoring students who misuse their illusion-based powers. After a minor disagreement, the pair separates. Alice then selects Masaki as her new partner, despite his previous relationship with Shirley. The story follows their experiences in a school where abilities related to tea and confections play a central role in high-level conflicts.
