真・瑠璃色の雪 ～ふりむけば隣に～

After losing both his parents, Hiroshi decides to rent a room in a mansion owned by the parents of his childhood friends Kotobuki and Youko. The rent was surprisingly cheap, since it was haunted by a ghost. But Hiroshi is the science club leader and doesn’t believe in ghosts. On the day he moved in, a hole opened in the floor, but he ignored it and went to bed. Woken up by a nightmare, he found a pot in the hole. He broke open the seal on the pot in curiosity and a girl came out, introducing herself as Ruri the yuki-onna. [from Micchi's blog] A remake of Ruriiro no Yuki.
