Spoiler warning
This review may discuss plot details.
Awful. This revenge fantasy has nothing to offer. It's not the edgiest one, it's not the goriest one, it doesn't have a good story, it has no original ideas. This thing just doesn't work on a fundamental level, it's far too edgy for it's own good but also doesn't go far enough for it to be so ridiculous it's entertaining. Nothing done in this story isn't done better elsewhere. It has every troupe you can think of from a stereotypical revenge fantasy. Lover doesn't love him, betrayed by comrades, the god of light is actually evil, former friends experiment on random people for funsies. It justreeks of being bland derivative nonsense. The MC also have a mediocre power, he can insta-kill everything in a radius. This is kinda interesting the first time but as they try to spice it up nothing really works.
The real mystery for this series is how I actually got through 20 chapters of this.
