A new Fantasy Isekai LitRPG about a young mage learning to summon supernatural entities as companions.

To survive a dangerous new world, he must make powerful monsters his allies.

After flunking the entrance exam to his dream university, Temaru Ryūta is left behind by all his friends and becomes a shut-in while preparing for next year’s exams.

This is only the beginning of his bad luck, because one summer day he is inexplicably transported to another world, where people like himself are expected to become Adventurers.

To make matters worse, he is assigned the Role of Exorcist. The most dangerous of all Roles.

Ryūta reluctantly becomes the apprentice of a suspicious older Exorcist, who turns out to be a ruthless teacher, and he soon realises that his new career will be fraught with danger and terrifying monsters.

Don’t miss the start of this unique new Isekai LitRPG from Dosei. Join Ryūta as he finds interesting companions and makes uneasy pacts with supernatural entities, all while dealing with corrupted Exorcists who have become a part of the darkness they were meant to fight.
