Please tell me this story has no girls and fanservice, no harem etc?

None

Thank God I’ll read then

It has women/female characters yes, but it's not a harem nor is there useless fanservice. There are noticeably less of them, but they get treated the same way as the male characters (which is why it's a bit of a shame there are less), ie. are dressed in ways that make sense, aren't inherently objectified/sexualised, aren't treated any worse or better by the MC (except there aren't that many enemies he slays that are women, but that might be due to censorship laws or the like, or just didn't cross the mind to have more female fighters on both sides)

Unless you like male fanservice lol..
