Kimi janakya Dame na Dorei Shoujo

A young man in modern Japan shelters a slave girl from another world. She believes she must devote herself to caring for him, but has trouble understanding when he explains that slavery does not exist in present-day Japan. As they live together, the two navigate their different assumptions while worrying about one another. Their shared life is awkward and amusing, and the girl wonders why he, in particular, has to be the one for her.
