――This is the story of an ordinary man who, having gained mighty magical power, is unwillingly elevated to godhood in another world――

Hayato Takada (30, virgin).

On his birthday, he was blessed by a god and obtained the power of a Great Sage. However, due to a divine mistake, Hayato was accidentally cast into an utterly unfamiliar other world, and reluctantly found himself forced to live there.

Amidst this unfamiliar life, the magical power he had obtained proved to be far more immense than he had imagined, causing Hayato to inadvertently wreak havoc in various ways. He annihilated forests and grew trees so large they became World Trees. Eventually, he became a being worshipped as a god by elves and fairies, unknowingly evolving into a living legend as a Great Sage.
