Hello! So, the first order of business is simple.

  To one Mr. Jans Stead: Screw you.

  Second order of business is a bit more relevant.

  A case of content theft: this narrative is not rightfully on Amazon; if you spot it, report the violation.

  Doom Guy Isekai, on September 22nd, was posted to Amazon under the title Doom Warrior and 100% copied from this story.

  So yeah, to repeat the first statement, screw you, Jans Stead.

  Anyway, here's the link if anyone is curious. I'm going to try and get the copyright claim back. Thank you guys so much for reading - in a weird way, the fact someone tried to steal it means it got big, so there's that.
