Mayuko Arisugawa has brown hair, brown eyes, stands 1.63 meters tall, and weighs 48 kilograms. She fights alongside friends Izumi and Usagi as a trio of magical maids, transforming using special pendants. Their core mission is restoring discarded or damaged machines to working order, driven by Mayuko's dedication to preserving mechanical objects. She fiercely condemns humans who mistreat their possessions, especially feeling intense anger upon encountering abused androids, convinced they experience emotions akin to humans.

Her key equipment includes a freely extendable staff and a cloud vehicle named Jindujun, both inspired by the Monkey King from Journey to the West, serving as her primary tools on missions. She wields the staff with considerable skill, employing acrobatic combat maneuvers when needed. Outside of serious duties, Mayuko favors a relaxed pace: she often runs late by taking extra time on tasks, indulges in snack breaks during errands, or explores with her cloud. Despite this laid-back demeanor, her loyalty is unwavering, and she refuses to abandon friends.
