This is an OVA released on October 27th, 2006. It is also classified as the 13th episode (thus a sequel) to Kashimashi ~Girl Meets Girl~. Hazumu confessed his love to Yasuna, but she turned him down him. To ease his heartbreak, he went to Mt. Kashimayama where he had met her first. However he lost his way in the mountain, and it was night time. He saw a big shooting star, and when he began to wish, he found out that something was wrong. It was not a shooting star, but it was a falling space ship. He was involved in the crash, but he managed to survive by the help of an alien. However, he became a girl due to the accident during the reconstruction of his body.

Kind-hearted Himuro-kun is unfortunate: when in deep concentration, stressed, or flustered, he involuntarily creates blizzard conditions for himself and anyone in his vicinity. During one such incident on the first day of his new job, Himuro-kun encounters the beautiful Fuyutsuki-san, who helps him break out of his nerve-induced ice. As it turns out, Fuyutsuki-san is his new coworker. At the office, the cool-headed Fuyutsuki-san offers simple and rational solutions to Himuro-kun's icy dilemmas—everything from helping him garden without freezing his plants to ensuring he does not melt during their tropical work retreat. Every time Fuyutsuki-san does something kind for him, the tempest of emotions he experiences inside embarrassingly manifests on the outside. As a result of the frequent snowstorms, Himuro-kun's feelings for Fuyutsuki-san are impossible to hide. Even though Fuyutsuki-san is unfamiliar with love, Himuro-kun remains determined to repay her kindness and warm her heart in any way he can.
