You Are Ms. Servant

君は冥土様。

A maid turns up at the door of high schooler Hitoyoshi Yokoya and asks to be hired, though her only real skill is killing. Yuki was orphaned as a child and raised by the people who abducted her into a life as an assassin, knowing nothing but cold obedience. After she saves Hitoyoshi's life, he takes her in, and she begins fumbling through housework she has never done while learning, beside him, what an ordinary life even looks like.
