Han Yuan is a girl who became a magical girl after accidentally receiving the Blessing of the Stars while living an ordinary life. With her long black and gray hair, achromatic clothing, and eyes that rarely show emotion, she gives off a cold and unapproachable impression to those meeting her for the first time. Her actual personality is quiet and blunt; she dislikes useless talk and doesn't bother explaining her feelings.

Her assigned magic is 'Absorption and Mitigation.' She can absorb magic, impact, and various energies that touch her to weaken their power and convert the absorbed force into her own mana. Because of this, while other magical girls dodge or defend against attacks, Yuan stands her ground on the battlefield by taking hits head-on.

Though she appears calm and composed on the surface, her true nature gradually reveals itself in battle. The stronger the attack she receives, the more her eyes change, and a smile—rarely seen otherwise—creeps onto her lips. When faced with a power strong enough to strike her down, she feels interest rather than fear. She harbors a strange madness that thinks, 'It doesn't hurt,' but rather, 'I want to take more of this kind of attack.'

Nevertheless, Yuan is not someone who recklessly enjoys danger. The moment a comrade is in peril, she steps in front faster than anyone, taking all the damage herself using her abilities.

Hidden behind her blunt speech is a surprisingly simple logic. If she hurts a little more, someone else can hurt a little less. That has been Han Yuan's way since long before she ever received the Blessing of the Stars.
