It's a basic revenge plot. Add on the Isekai and you get an even more basic plot. The protagonist had a lot of potential, but they made its so the protagonist' whole personality was revenge. That's not a good idea if you want a good story. So in the future it may get better but for now it's borderline average.
This story has an extremly interesting premise, but the execusion is absolutly shit. The main character is a basic edgelord who grows stronger with negative emotions, but despite that he goes around with an annoying FM who's not intersting or compelling in any manner, shape, or form. Not only that, but his ability is just obnoxious. Instead of having an interesting fight with his enemies where he display's hispower in the name of his revenge, he just walks over to them and they instantly die. It's probably one of the least promising revenge stories I've ever seen and while it may be a good power trip and have some nice art, I can't really think of any reason to read it.
A mediocre power fantasy with theme of revenge. It builds on classic trope for such series mainly betrayal by the group, where in truth each individual has bad and twisted character while pretending to be nice for some personal gain. The same can be said about the betrayal leading MC to obtaining seriously OP power. The resulting edgelord personality is apt description for MC in this scenario. The only bit novel thing at least for me was that the bad character had some effect on relationships among the other party members as well . The MC gathers some supporting characters as one would expect all females, which become quickly romantically interested in the MC. What I found bit strange, there were other parties of heroes as well, who are used either as additional antagonists or as cannon fodder/plot device. In regards to power for action scenes it takes approach of powering up, when necessary. Usual elemental magic mechanics are set aside for dualistic mechanic of light vs darkness. Its’ only potentially interesting aspect is the supposed connection between the two. As the MC is getting stronger so should the main antagonist.
The series has some gruesome moments including rape. It isn’t for people sensitive to that kind of happenings.
Visually the series isn’t that impressive either. The art style has visceral feeling to it.
Overall, I wouldn’t recommend the series. There more enjoyable alternatives even among revenge series.
Release frequency: 6 months between each volume release.
Japanese difficulty 5/10 (see my profile for details about various difficulty scores)
This series is without furigana. Except some specific terminology for the power system, it’s mostly an average vocabulary without some complicated words as far as I can remember.
This review is written after reading 4 volumes (all existing at the time).
 For example one of the party members, the knight, is jealous of the hero. The priestess sleeps with the hero just for her own benefit.
it ok not very interesting
It has the typical start where the MC gets betrayed which is fine but i honestly can't stand how he keeps telling he''s enemies about the details to his power. It really sucks like what idiot would consantly warn his/her enemies thaat i have this certain power and these are the limits to my power before every fight
