Harem in a Labyrinth

Didn't read the fic yet, but the fact that you intend to "rectify" Michio (the guy somehow managed to come off as beta Japanese MC despite losing his V-card and I still don't know how he pulled that off) is enough for me to give you encouraging 5-star.

Give 5 Star because this is the only fic about Harem Dungeon so far i here. And i really like the original manga, so 5 stars bro!

This is a premature review, given the relatively new chapters that just released. Because of that, I will try to be constructive without spoiling. First off, I like the idea of using Isekai Meikyuu de Harem wo as a fanfiction and the OC so far. The writing style and quality have no problems and I didn't spot any grammatical problems which stood out. In fact, it's easy to read and fun. The only problem I have is that this story seems to want to have a stronger more secure version of Michio. While this is fine, it seems that it will go for a more 'OP protagonist enjoys the different aspects of the world without worrying' route. If that is the case, I would recommend spending less time focusing on the stats and equipment of every small encounter and more on the character interactions. It's just a recommendation, but it would allow more space for what I believe the author is attempting to go for. Of course, you can still be going for a similar realistic isekai struggle and can ignore what I said, as there isn't too much to go off in under 15 chapters. I still recommend for others to read it, since it is still fun despite my seemingly long complaints. Definitely going to be a fun ride down the road. I wish the author luck if he needs it.
