This is the worst manga I ever read with difference (I have read at least 800).
Knowing that this work has been published by someone disgusts me.
The isekai genre is not bad, it's the mediocre authors who ruin everything.
This manga would be used as a template for deciding whether a manga should be published; if it's even remotely similar to this one, it would lead to instant rejection.
I'm sorry if I sound very agressive and unforgiving but I want to express my feelings in this comment and this monstruosity can't je described with simple words
The disgust I feel when reading this is only comparable to the hatred the machine feels in "I have no mouth and I must scream."
I could do a University degree final project level essay on how bad this is and how bad everything inside this is. I'm not joking, each page has something wrong and bad.
