Aria Kisaki

A girl who attends a different school from Okumura. She first appears as a second-year high school student and a budding cosplayer. She is unfamiliar with cosplay, manga, and anime. She deepens her friendship with Lilysa and Nonoa after encountering them during a joint photo shoot, and eventually, she starts frequently visiting the manga club room after school with Nonoa, despite being an external student.

Her father is the manga artist Kisaki Yoh, who has gone missing. She still loves his works and decides to become famous through cosplay to convey this to him, dressing as Melia from his manga "Valkyrie Front" at her first event.

Gradually, she develops feelings for Okumura, who has been a support to her regarding her dreams and her father, and she begins to subtly make advances toward him.

She often cooks in place of her busy single mother, making her skilled in cooking. Her cosplay creation skills are initially lower than Lilysa's, primarily providing support and encouragement, but her sewing skills improve over time.
