Shin Ruriiro no Yuki - Season 1

Makabe Hiroshi, an individual with an interest in science and invention, relocated to an apartment owned by the parents of his childhood friend, Youko. The decision was based on the very low rent, despite rumors of a ghost inhabiting the room. After his move, while preparing for a party with Youko's elder brother, Kotobuki, scattered machine parts on the floor short-circuited and exploded. The blast created a hole in the floor, revealing a strange jar within. From this jar emerged a blonde-haired snow fairy named Ruri. Thus began the sudden cohabitation of Hiroshi and the snow fairy.
