The fact that you need to explain to people why mc is grateful to the strongest ninja in his village is crazy...

I enjoy this story but I really can't stand how much you explain everything. You use 100 worlds when 10 would do for everything. This chapter was supposed to be about first conversation with Tsunade but you spent what felt like 2/3 of it describing how genjutsu works and some political stuff. This sort of thing happens very often and is especially bad when you do it mid conversation to the point that I have to go back to remember what we're the characters even talking about before you started doing your world building for multiple paragraphs...

Ren could try his hand at summoning jutsu gatcha. If he is reverse summoned to a clan with sage, he could learn sage mode or at least get some info on nature energy to make some interesting seals.

There is no need to attack me straight away. I'm just sharing what I've seen in other stories. Harem dynamics are generally much better when everyone in harem likes everyone else, and there is no serious competition.

There is no need to attack me straight away. I only shared what I noticed from a lot of other stories and what seemed to be the most realistic approach to this. I'm enjoying the story and hope that it won't become full of angst and drama about Izukus harem, so I'm giving my suggestion with hopes that author will notice them and maybe take something out from it.

Planing harem when the first girl is jealous of any other girl getting close to him is a horrible idea. Harem only works if everyone is on equal standing, and Camie already put herself as a 1st wife, which will only create conflict in the future. It could still work if Camie was Bi and was trying to seduce other girls together with Izuku, but she didn't show any interest in girls up until now.

With every chapter, I fear the harem becoming too big. Really hope you won't go over board and stop at max 3 girls.

Mc is gaslighting himself super hard with canon still being a thing. He needs to let go and start living his life.

My impression is broken, dropped...

Best I can do is 3, take it or leave it.
