"―――Everything, every last damn thing, just feels... wrong."

Inunashi Mamoru mutters these words as he heads back to Mayunoha Town, a location tucked away in the heart of Taishou-era Japan. The simple life he once knew with his mother has been turned upside down by her sudden disappearance.

Suddenly, a letter from his father, who's only known through stories, arrives. It bears harsh news: his mother's death and details of her funeral in their forsaken hometown.

"Come back to the place you left behind," the letter seems to dare.

Caught in a whirl of confusion and fear, Mamoru is compelled to return, holding onto this singular lead.

The small town is a strange mix of the familiar and the unknown, where encounters with old faces and new figures will set the wheels of change in motion.

"......Why........................"

A hoarse voice of a woman signals the start of a tragedy as death comes knocking at the inn known as Kaerazu no Yakata (Mansion of No Return). Mamoru's return to Mayunoha Town has awakened the once-sleeping gears of fate, like blood surging through long-dormant veins.

In this world, the dead stay dead—a truth as inevitable as any curse.

"Ah, let's orchestrate the chaos. Cue the puppet dance of this grand masquerade," the demon laughs.

The curtain of tragedy has been raised, and there is no turning back―
