Everyone knows the story of the summoned hero who defeated the Devil King, but no one knows about the man who summoned him.
Eriq Grael is a genius wizard shunned by the church for his heretical theories on Class Evolution. But when war breaks out with the demons and there is seemingly no hope for humanity, maybe a little heresy is what the world needs.
Field research isn’t easy though. Eriq will have to explore uncharted wilds, battle horrifying beasts, and even make deals with eldritch demons, in order to uncover the secrets of the divine system. Only after that, maybe, just maybe, he might be able to develop… The Isekai Theory.
This story is about: The life and death of Eriq Grael, the man who invented the isekai summoning spell. It follows his journey through studying the world’s magic system, overcoming the war against the Devil King, and learning to move forward from his dark past.
Readers can expect: character focused drama, slow burn (seriously, don’t expect any Isekai-ing any time soon), darkness, occasional comedy, surreal/fantastical environments, and an extensive litrpg magic system which will be slowly discovered with the protagonist. The Isekai Theory will be very, very long.
