Shin Ruri-iro no Yuki

Makabe Hiroshi, a young man with a passion for science and invention, moves into a cheap apartment owned by the parents of his childhood friend, Yoko. Despite rumors of a ghost haunting the room, he is drawn by the low rent. After settling in, he prepares a party with Yoko's older brother, Kotobuki, when a short circuit causes an explosion among scattered machine parts.

The blast tears a hole in the floor, revealing a strange jar. From it emerges a blonde snow fairy named Ruri. Suddenly, Hiroshi finds himself cohabiting with the mysterious fairy, beginning an unusual and intimate living arrangement.
