Just a note: This is my first review, so pardon me if it has odd errors or is formatted wrong.
Why I must Write This Review: Essentially I have been forced to give this review, not out of the enjoyment I received from the series (although there is much), but simply to ask people to hold their final verdict until the story is closer to being completed. Although the story may not seem like it, majority of the important information of the series is withheld until later. This in turn, makes it appear as though the writer made people had powers just to have powers. This is not the case. Everything within the manhwa can be explained, just not until later. Think of it as a slowly unfolding mystery. I won't say anymore to avoid spoilers.
Story: You can read the synopsis, I won't be restating it here. The story in the beginning seems simple, and possibly even bland to some. A classic zero to hero story, great. However, this simple outlook could not be more misguided. Just know that the story itself in the beginning is highly enjoyable to most people, while the writing near the end (which has not been shown yet outside of the LN) is very well done. This eventual reveal in the LN truly blew my mind, so I'm giving the manhwa a 10/10 since its been a truthful adaptation so far.
Art: Nothing much to say. Fantastic art with its own unique style.
Character: Unfortunately, the one thing that can't really be carried over from a LN is all the internal dialogue. I would give the LN protagonist a solid 10/10, but for a manhwa, it only gets an 8. He's still a good protagonist, and you can visibly see him change, but the effect isn't as strong as the LN.
Enjoyment: The series is so enjoyable that its addictive. I blasted through the chapters lightning fast, and I didn't even realize. If nothing else, read the story just for a good time.
Summary: Great art, great story (which has not been entirely revealed), and good character (great in LN). Would recommend to anyone.
