WTF did you guys read ?
First of all it's only 2 volumes and it's told (and retold) from many different perspectives, so there is basically no story at all, and 2nd: what was even the point of it all ? The MC wakes up, stuff happens and he goes back to sleep, the end.
The ending didn't really feel like an ending, after one of the random battles it just ... ends. Nothing important is ever explained.
It really feels like the author wanted to continue but seeing what a poor job he did, he probably had very low sales and had to cancel.
Also I really hated the way the author added in all those irrelevant bits between the dialogues, "i felt this .. I noticed that "... irrelevant, stating the obvious, needlessly dragging out revealing stuff/people that was hinted at pretty obviously. Talking about useless things, even acknowledging they are useless and yet still including them ...The authors story telling skills ... just awful.
And what's with almost all the characters laughing at the beginning of almost every sentence ? they're demons, I get it, but stupidly laughing at everything just felt super odd and wrong, completely unrelatable.
I did like that he told the story from so many different viewpoints, but that's about it, the story was short, pointless and lame, the characters had some development but didn't really do anything, they fought a few pointless battles I guess.
It's really no wonder why this didn't get any sort of adaptation.
