Seize destiny—A scarlet trail across time and space.

A girl who rarely shows what she feels, keeping her impulses sealed away inside. Drawn to her classmate Rena's strength of spirit, she sets out to become a dragon rider.

Capable and quick to master almost anything she tries. Bold and driven enough to earn a flying dragon license at a young age, though she carries conflict with her family.

Her parents work with flying dragons, and she hopes to follow a similar path in the future. Of the four, she knows the most about flying-dragon ecology.

Unruly, hyperactive, and a natural genius. Her curiosity is so intense that everything catches her attention, and her interests shift one after another. With ASD- and ADHD-like traits, boundless stamina, and a habit of forgetting food and sleep, she barrels ahead like a typhoon.
