It's not much harem it's like a game where you keep getting told to go solo with an army under your command
^ As that one stated; not much focus on the harem. Granted there are a few chapters, but it's mostly focused on the plot and him getting stronger with the luck of finding things left and right that seem OP only for reality to later show him he is still weaker than others. It's worth the read!
The focus is not the harem though
I hate harem, but I love this. Harem is basically an after thought, and it just focuses on him getting stronger
thinking of starting this next when i finish yuru camp because people are saying it is good but i kinda dislike harem..
