Kimi wa Meido-sama.

Hitoyoshi Yokoya opens his door to find a girl in a maid uniform asking to work for him. It quickly becomes clear that her real expertise is not cooking or cleaning but assassination: she was raised from childhood to kill and knows almost nothing about ordinary life. Hitoyoshi tries to send her away, but after she saves him from an accident, he decides to give her a chance.

He names her Yuki and begins introducing her to simple experiences her former life never allowed: cooking, school, friendship, and enjoying a day that requires no one to die. Yuki is exceptional with weapons and disastrously bad at being a maid, but Hitoyoshi's home gives her a place where her worth is not measured by how efficiently she can end a life. Each new ordinary experience lets her imagine a future unlike the past she was created to serve.
