I made an account, just so I could comment on this.
While I like the genre Isekai in general. This is by far, the best in use of it I've seen so far. It's extremely interesting to see the character start from basically nothing, and power up, it makes the story a lot more relatable, and a lot less bland than just being OP from the start. I hope this goes on for a long time, and maybe even gets an adaptation, I'd love to see this brought to the screen, if it retained the charm.
That also being said, this is one of like.. 3 magnas I've spent the time to fully read, so hopefully, the fact that I've actually invested time into reading the whole thing should show that it's well worth it.
