Author note: I'm not going to lie, I was high and drunk as hell when I came up with the idea for this. It was about a week ago, and after playing a drinking game, I decided to read a story on this site called "Doom Guy Isekai" When I wanted to see what other characters I could isekai, so I thought of the gigachad. Now here I am, a week later when I found the idea written sloppily in a notebook of mine. And I want to see if this could actually become a book. Anyway here's the synopsis. In a world where concepts are worshipped instead of gods, individuals choose to devote themselves to these powerful ideas, gaining both their abilities and drawbacks. For example, the concept of magic grants control over mana but weakens physical strength. In the year 1206 some worshippers of the underworld discover a mysterious book with the power to manifest their concept physically, a transformative journey unfolds, blurring the lines between the abstract and the tangible.
