Kanokon EP7 - Won't You Warm Me Up?

Yukihana, a yuki-onna from Chizuru's family, tests the bond between Chizuru and Kouta by creating a powerful snow storm only around the school. As the students try to stay warm, Kouta, Chizuru, Nozomu and Tayura try to search for Yukihana. Tayura gets taken away by a band of snowmen, and the others run away into a nearby classroom where Chizuru and Nozomu use their bodies to warm up Kouta. Yukihana finally appears, and as Chizuru and Kouta are trying to run away, Yukihana stops them. Chizuru and Kouta combine, showing how strong their bond is, and thus Yukihana stops the snow storm, and informs them that Chizuru's mother wants her to bring Kouta back to her hometown.
