Traveling Through the World of Flesh and Blood, You Want Me to Fight Against the Evil God?

"It seems like that; but it doesn't seem like that." What's more terrifying than being confused is not knowing why you are confused. "I fear, I desire, I gain, I become!" When the growth of all life begins to be distorted; when the truth of universal adaptation begins to distort; when the history engraved in the history books begins to blur; when a strange evil dream emerges from nothingness, the indescribable great existence will gain his most true believers. Cthulhu + growth-oriented protagonist + darkening + no "female" protagonist + no harem + no good or evil, I invite you to witness this weird and fantasy world.
