I very much like the premise of no harem and am glad with how the story is progressing.
The main character is also able to use his intelligence (despite the fact that he went to a place which I presume was a brothel, though that could be my misunderstanding, or not.) Not to the point of extreme genius though, as he could have wished for primordial eyes or something that could turn into any sort of special eyes, well you get the point.
There is also a need for improvement in the transition of the story, everything just happens so suddenly or that there is a vague flow of events happening and the mc seems to have some natural affinity to women despite the no-harem tendencies.
The only other misgiving I have is that it's still new and that there are very few chapters to immerse to. I hope the story will progress to the original premise of absolute-no-harem and no blushing beauties everywhere the mc goes.
It would also be presentable if the mc could go unto different universes, and actually immerse himself unto them, rather than the clones themselves doing the task for him, and I also would want for the author to further explore the various important characters in the worlds the mc explores, such as the first featured known character (Bell Cranel from Danmachi), and in this regard, it would be nice if the mc could explore the different sides of these important characters that were not shown in the anime or in the different artworks they originate, in this way, the story will add a unique twist unto it rather than just following events without experiencing them thoroughly. I myself would very much want to know what main characters from famous novels do in their everyday lives when they're not collecting women, pursuing a one-in-a-century fortune, or committing genocide. Though him building strength could be done by his clones, it would be best if he also had significant development such as in character, where in the earlier parts, isn't as profuse. I have already made such a fuss though I am not sure if the author even reads comments.
