There was a link from another newer series to this one, someone said this one was better... I'm not really seeing that.
I liked the time taken to show the efforts the MC and his brother were putting in. It was nice to see that the MC still lost to his brother and had more to learn.
But the mangaka's tendency to not understand what scenes to skip or include seems to have not improved much. That was a brutal transition. I think their foreshadowing has improved in the newer series but not that much... how hard is it to learn the rule of 3 and implement it in a way that makes sense?
The art is slightly better in the newer series, and the action sequences are improved.
It's like the mangaka skipped over parts that are shared between the usual isekai (like first guild entry and introductions) in an attempt to be more efficient... then adds in useless scenes like he was banking them in order to add unnecessary sexual shit.
Oh, it's got the erotica tag on it. :/
