The Land at the End of Snow

There was a colorless, fallen country... In such a place, Uren (雨蓮), who continued killing people, meets Hakusetsu-kun (白雪君), the white snow prince of this country. Ren is drawn to Hakusetsu-kun, who speaks of an ideal to restore color to the colorless country. At the end of this, will the country without color be able to regain its color? Hakusetsu-kun and Ren make a promise to each other. The two of them run forward to fulfill that promise.
