I am 17 chapters in and found it was very very bad.
It's a porn manga with the mentality of a highschooler.
The author just think with his d*ck and can't make believable reaction.
Everybody supposedly knows that it's a death games where you have to follow the rules or you die and they all...
While the plot isn't so bad. (I do like Isekai)
I do find the story very VERY VERY VERY slow for nothing.
And because we know MC is ultra overpowered, there is no tension... 10 months of chapters just for a useless fight...
It was a one time, it was sudden and it was the first time. And the ratio fight/slice of life was still very much on the slice of life side.
This battle comes after the battle with the husband in the box which was itself before all the preparations for the battle. The ratio shounen manga/slice...
Same.
While I find these battle very nicely drawn. I do think it would have been better if they weren't there.
I'm okay for high stake intrigue, but then just skip to the important parts.
