Harutsuge to Yuki Musuko

"As Yukionna-sama's living sacrifice, you shall call upon the arrival of spring."

In Fuji Village where the legend of Yukionna remains, preparations begin on the morning of New Year's Day for the ritual to be held on the coldest day of the year. The young men who have inherited the blood of Yukionna, thus named the Three Houses of the Gokusho, spend their days until the ritual aiding the living sacrifice, the Revelation of Spring. In this enclosed world bound by laws and tradition, the young men uncover mysteries of the village and its rituals. Before long, the village is faced with a situation never before seen.
