This is probably one of the best manhwas to grow over time and age like fine wine. Starting from the storyline to the art quality and fight scenes, everything developed really well. Storyline: (7/10) The storyline was well paced, especially in Season 1 & 2. It achieved a perfect balance between action scenes and characters development. However, starting from Season 3, the pacing began to slow down. There was a lot of unnecessary information, which made it somehow boring?. Despite this, the manhwa still managed to deliver a satisfying story. (Spoiler Alert) The ending was really nice, with Woon Seong marrying A-Yeong. This humanized the main character, movingbeyond the character who only lives seeking revenge.

Character Development: (9/10)
The character development was one of the best out there. No character felt overpowered from the start, everyone had to work hard and train growing more powerful.
However, I did have some comments on Season 3. A couple of overpowered characters appeared out of nowhere, and some of the main old characters seemed to be neglected.

Art: (10/10)
In the beginning, the quality was absolutely terrible, but by Season 2 and especially in Season 3, it reached a peak level. This transformation develops a connection between the reader and the manhwa.

Fight Scenes: (10/10)
The fight scenes were interesting, drawn well, balanced, and realistic. Even Woon Seong, the main character, faced difficulties in winning most of his battles, which made the fights more better.

Overall:
Heavenly Demon Reborn! is a fantastic manhwa, especially for fans of revenge and martial arts stories, it’s a highly enjoyable read.
