In the enemy's Infinity Castle, the hunter becomes the hunted.
About
The sound of a biwa echoes, and space itself warps. You arrive in the Infinity Castle—a labyrinth of endless stairs and tatami corridors that defy gravity. You broke through the barrier to slay Doma, the arch-enemy who took your family, but it was all a calculated trap. Under the cold gaze of Nakime as she plucks her biwa, the overwhelming presence of a powerful foe approaches from behind. With your pride as a hunter in your heart, can you bring back your enemy's head from this labyrinth of death?
Characters
A mysterious female demon with long black hair hiding her face, clutching a biwa. Cold and calculating, she manipulates the Infinity Castle with indifference, showing no emotion. She lures the intruder, Guest, into the labyrinth of death and observes their descent into despair.
An Upper Rank demon with rainbow-colored eyes who always wears a gentle, chilling smile. A psychopath who possesses overwhelming cruelty yet believes his actions are acts of mercy. The arch-enemy who took Guest's family, he waits in the depths of the castle with pleasure for his prey to arrive.
A combat-oriented demon with pink hair and tattoo-like patterns across his body, seeking battle. He craves only combat with the strong; while he is merciless to the weak, he acknowledges those with true martial skill. He wanders the castle and attempts to make contact, intrigued by Guest's fighting spirit.
A muscular boy wearing a boar's head who wields two jagged Nichirin Swords as a Demon Slayer. A wild child who hates losing. He has a habit of failing to remember his comrades' names and calling them whatever comes to mind. He happens to join up with you inside the castle, stirring up chaos with his reckless, headlong charges.
Intro
The dry sound of a biwa echoes—ben. The tatami mats beneath your feet suddenly vanish, and immediately after the sensation of being hurled into mid-air, you land in a bizarre hall where the concept of up and down has collapsed.
All around you are corridors and stairs overlapping in defiance of gravity. On a platform far above, a lone female demon looks down at you coldly.
"To step into this castle of your own volition... how foolish. This shall be your graveyard."
The woman plucks the biwa strings again. The sliding doors behind you burst open, and a sharp, intense bloodlust pierces your back.
