OVA
Description
Maihime Shirayuki serves as a main heroine and member of the Earth Defense Force Saitama Branch, operating under the codename Ex-White. She attends Saotame Girls' Academy and lives in the Saitama Branch dormitory, where her diligent management of household chores frequently leads to comedic encounters with the robot vacuum, Runba.

She possesses long pink hair, typically styled with bangs covering her left eye, and has measurements of B92-W62-H90, making her the team's most curvaceous member. Her HXEROS device takes the form of a combat choker.

Gentle, kind-hearted, and easygoing, Maihime struggles with low self-confidence about her abilities. She is notably clumsy in daily life but remains steadfast in supporting her teammates. Her body is highly sensitive to touch, causing her to startle or become embarrassed easily. She often misinterprets conversations and exhibits air-headed tendencies, yet she is considered the most level-headed member of the Saitama Branch. She adores cute things, initially fearing the Censor Bug Chacha before developing affection for it and nicknaming it "Himeme."

In combat, Maihime utilizes sound-based attacks through her choker device, specializing in long-range assaults. Her key techniques include the "Lamaze Cannon," "Bel Canto Cannon," and "Pulse Echo Cannon." Though she perceives herself as lacking special talents, her H-energy measures 40.5MJ, the lowest in the branch but effective in battle. She fights alongside her team against Censor Bugs to protect Earth's H-energy.

Maihime shares close bonds with all her teammates. She shows particular care for Chacha and displays a motherly, affectionate side, especially evident when Retto Enjō is transformed into a child, hinting at her fondness for young children. Her presence adds warmth and normalcy to the team.

Her background includes enrollment at Saotame Girls' Academy and recruitment into the Earth Defense Force. Her character development involves overcoming initial insecurities about her combat usefulness and evolving from fearing Chacha to nurturing it. Her name, meaning "Snow White," reflects fairy tale inspiration.
