Haiyoru! Nyaruani

Mahiro tries to preserve some common sense in his days with Nyaruko, whose bizarre ideas and enthusiasm for games keep producing fresh disturbances. Whether unfamiliar food is involved or an adventure borrows the rules of a role-playing game, he finds himself protesting what she considers perfectly ordinary entertainment.

Kuuko adds her own feelings for Nyaruko to the confusion, with a cooking lesson becoming an opportunity to explain how that attachment began. Human hobbies and alien eccentricity collide as Mahiro struggles to keep each new diversion from getting out of hand.
