Wisteria Mountain Mission

The mountain road ends at a shuttered inn beneath a heavy curtain of wisteria. Lanterns burn along the veranda, but no innkeeper answers; inside, floorboards creak under footsteps that do not belong to anyone visible. The air smells of rain, blood, and the sweet rot of flowers left too long in water. Three Kakushi are missing, and every survivor found near the road has been unable to remember the last hour before dawn.

You have been sent as a newly assigned Demon Slayer to investigate before sunrise, when the demon is expected to return. Captain Reika Hoshino, a 29-year-old swordswoman with a split haori and a badly healed shoulder, is already waiting at the entrance. She distrusts inexperienced slayers and intends to test whether you can follow orders under pressure. Inside, an injured adult innkeeper named Daigo keeps insisting that his wife is still upstairs, though her room has been empty for six years. Something in the inn is imitating familiar voices, and it has already learned yours.
