However, in the wake of his death, the soul of a man who died from overwork in another world reincarnates into Shinya’s body, and he awakens once again as Shinya Mikage.
Upon opening his eyes, the man realizes that the original Shinya has already passed, his own soul has taken over the body, and he now possesses a unique ability—"World Connect."
Furthermore, after suddenly being thrust into a nightmare world, he encounters a grotesque monster and enters into a contract as its "Gatekeeper."

What exactly is the "Gatekeeper"?
Guided by an enigmatic voice in search of the truth, he finds his purpose while wielding his special powers to battle twisted monsters and entities that warp the very fabric of reality.
