OVA
Description
Tsukasa Tomii assists the Shin-Takarazuka Academy Cosplay Club leader Ranko Takara and serves as the group's expert seamstress. Her shyness and lack of confidence, especially regarding cosplay competitions, stem from a fear of performing before audiences. This keeps her primarily in a behind-the-scenes support role.

A rainy encounter with East Oizumi Academy's Chako Hasegawa sparks Tsukasa's journey into direct competition. When Ranko challenges East Oizumi to a formal cosplay battle, Tsukasa is nominated as Shin-Takarazuka's representative against Chako, forcing her to confront her stage fright and self-doubt.

During the decisive competition in East Oizumi's gymnasium, Tsukasa embodies Queen Serenity while Chako portrays Princess Serenity. Encouraged by both Chako and Ranko, Tsukasa overcomes her apprehension, demonstrating growth in confidence and competitive engagement.

Tsukasa has dark brown hair and violet eyes. Her narrative includes a blue-haired woman who leaves flowers at a grave and attends the competition, later revealed as the Shin-Takarazuka group's limousine driver.
