Story: In this story the main protagonist is given something in his return, that something is not what ends up making him powerful. This makes the story of growth of the protagonist that much better and keeps the story compelling. If you want to see a main character actually grow not just in strength but also as a person, I would give this a read, I didn't regret it.
Characters: The main protagonist is great as well as the reoccurring side character. Lot of the characters we would call villains have their own reasons for why they are acting the way they are and is not very black and white which I found nice as well.
Art: pretty nice if your used to the manhwa style of art that is typically used a lot.
