After dying prematurely from an incurable disease, Yuka Hikano finds himself in a mysterious realm filled with endless doors, each concealing divine gifts from powerful deities. He is not alone—others who have met the same fate of death stand beside him, unaware of the trials that await.

They are put through various tests and eventually transmigrated into different worlds. But these worlds are nothing like the Earth they once knew.

For Yuka, however, this apocalyptic world feels eerily familiar. It is a realm of endless war, devastation, and chaos—a world he once played in a game. Certainly not the kind of place one would wish to be reborn into.

From infancy to adulthood, he must gather strength, knowledge, and allies to survive the horrors that lurk ahead. But when he awakens a system granting him a power beyond imagination, he soon realizes that blessings can also be curses.

Infinite Mana...?

What could possibly go wrong?

For as long as humans have feared the darkness, they have also sought ways to expel it. The art of exorcism—a sacred practice meant to drive out spirits, demons, and malevolent forces—has evolved over centuries, taking different forms across cultures, religions, and mythologies. Though often shrouded in superstition, exorcism has remained a powerful and deeply ingrained aspect of spiritual warfare.


The earliest records of exorcisms trace back to Mesopotamian civilizations, where priests known as "Āshipu" performed rituals to banish evil spirits. These ancient exorcists inscribed incantations onto clay tablets, invoking deities such as Enlil and Ea to drive out malign entities. Babylonian texts describe the use of fire, water, and sacred objects to cleanse individuals who had been possessed by malevolent spirits.
