Each plate features crisp panel lines and wear patterns that suggest battle experience. The interchangeable parts include armor segments, optional cloak pieces, and articulated hands that allow a wide range of combat stances. Fine sculpting details emphasize Mizuki's stealthy silhouette, while the glossy finish on the sword and headpiece adds a premium feel. The MMS3 scale promises seamless integration with other Busou Shinki figures.

Mizuki is portrayed in the Busou Shinki universe as a disciplined, cool-headed ninja who moves with the hush of falling rain. Trained from a young age in stealth, she favors precision over force, using swift strikes and misdirection to outmaneuver opponents. In her stories, she travels with a small squad of Shinki guardians, protecting her friends while seeking hidden knowledge about ancient technology that powers their armors. Her personality blends restraint with a fierce loyalty: she will risk herself to keep allies safe, preferring calculated, patient tactics to brute strength.
