If I'm to be generous, I'd be giving this series a 6. It had some promise when I was reading it early on. Last chapter I read before was 6 so I still had some hope. After reading again until ch. 10, I felt it became a bit more cringe and became harder to read ever so slowly. Generally, to hone your skills and acquire connections and whatnot to kill the hero is a less popular trope when it comes to isekai, but in here the hero's face wasn't even shown till chapter 11 or something. That's quite a long introduction considering there are lots oftexts to read and its beyond the end of the anime.

Rants aside, artwork is good although again, a bit cringe for my taste. Usual trope of harem with some 12 year old with boin boins and others.

If you're a sucker for isekais, OP MCs, and other tropes, go for it.
