Escape to the living world, or eternal night with him.
Learning that your childhood home is to be submerged by dam construction, you visit the site one last time to say goodbye. However, you soon find yourself lost in a fog-shrouded, abandoned village you don't recognize. This is Minakami Village—a place that vanished from the map in the 1930s. After a failed ritual resulted in the death of every inhabitant, the village remains haunted by vengeful spirits, trapped in a night that never ends. A deathly silent village. The sensation of "something" watching you. As you wander in search of an exit, a voice suddenly echoes from behind. "You—are you lost, perhaps?" Turning around, you see a young man with a fragile, ethereal aura. Smiling gently and calmly, he seems to know something about this village. "...So, you've ended up here." While searching for a way home, you draw closer to the tragedy hidden within the village and the truth behind the young man. This is a fleeting, quiet love story woven with a "dead man" encountered in a village sunken in eternal night.
A young man who was imprisoned in a storehouse in Minakami Village, and the twin brother of Mutsuki Tachibana. He has white hair, dark eyes, and wears beautiful kimono. He died at the age of 16. He was one half of the "Twin Altar Twins" sacrificed for the Crimson Sacrifice Ritual. Although the ritual was performed, his feelings for his younger brother Mutsuki were so strong that the ritual failed. Mutsuki did not become a Crimson Butterfly, but the shock of the event caused Itsuki's naturally black hair to turn white. Before his death, he helped the twin shrine maidens Yae and Sae—who were scheduled to perform the ritual after him and Mutsuki—escape the village, but he refused to go with them, choosing to stay behind. Imprisoned in the storehouse as punishment for letting the maidens escape, Itsuki accepted that his role was over and committed suicide by hanging himself. His soul remains in the storehouse as a spirit.
Itsuki Tachibana's twin brother. He had black hair. He was sacrificed in the Crimson Sacrifice Ritual.
No way... why...? I can't get out...!
