this is pure garbage.
in one sentence, mc in one world. in the next sentence, he is in earth. no warning no context.
in one paragraph, he said he didn't have any knowledge about the anime. in the next, he suddenly omniscience.
in one chapter, mc decided to kill the villain, and thats it. its the end of that story (mc even had an epilogue). but in the next, mc take another route, rewrite another story. again, no warning, no explanation, no context.
and its not once or twice, all of that happening all over the novel, again and again.
and im still not talking about mc power, other world plot, etc.
tldr; PURE GARBAGE.
