One Punch Isekai Man

From the 9 or so chapters I've read, my initial impressions about this book are... well, kinda neutral. I'll rate it 3/5 for now. Above average, but it's boring and slow. The world feels like a mystery and sometimes things don't make much sense. Now, do note that I'm judging it like I would an original story and not a fan fiction, because really, it's not really much of a fan fiction. The world is original. Sort of. The cameos from characters like Ainz and that other protagonist (though there's an original twist here) was interesting but it didn't really bear any fruit. The two side characters so far have been okayish. Saitama has OC tendencies and often doesn't act like OG Saitama. Though, I can't fault author too much for that. Anyway, ignoring the mistakes made during writing, I would appreciate if Author used simpler, easier to understand terms. I mean, is it really necessary to blurt out complicated words and sentences in a fic? Maybe it would be fine if Author was apt at writing, but that's not quite the case either. The writing is mediocre. (Readable, but not clear enough for me personally) Anyway, these were mainly just my personal opinions. I'm sorry if you were expecting a 5 star review. Hope this 3 star review helps you in any way. Don't stop writing and keep it up. I still think the story has potential to grow into something more fun and entertaining than what I read in the first 9 or so chapters.
