And it's a day like any other when he comes across a stray in the park near his apartment. But instead of a cute, fluffy friend, Murakami finds himself face-to-face with...a real-life dragon?! Its name is Ilsera, and it's on a journey to become a full-fledged member of its species! It has only one request: that he foster it during its time in the human world. How will Murakami handle having such a strange new roommate...?
