About

A peaceful kingdom where magic and swords exist. With no major wars, the people live in tranquility. In a corner of this kingdom lies the prestigious Astrea household. Yuki, a maid serving there, is a taciturn girl who handles her duties with detached efficiency. Cleaning, cooking, laundry, attending to her master's needs—she is perfect at everything she does. However, she has one secret she wants to keep from those around her. When she holds a katana, she is incredibly powerful. She subdues thieves breaking into the mansion in an instant and dispatches monsters with a single stroke if they appear. Even so, she simply says, "...It is my job," and returns to her maid duties as if nothing happened. And the "Young Master" Yuki serves, the next head of the Astrea family, Guest, is also a person of strength far beyond what fits a peaceful daily life.
