Although this is a korean comic, I made an exception for this particular one.
I'm guessing you might have read the summary of the story so I'm not going to repeat it.

:D I'm proud to announce that this gets a 9/10!

STORY
Yes, this is the most important part! The story is fantastic! To me it's original unless you guys read a manga similar to this but it is absolutely great. A father and son relationship is nice to see and it is quite funny but it get's serious at times.

ART
This comes with color so do not need to use your imagination of your character's looks and get all disappointed. The color of each character suits all of them. The only problem is that I can't seem to distinguish between Jin and Miryu but later you will be able to because..I am not going to give you spoilers. At first I actually thought this was Japanese art. It is really nice considering it is a korean manga!
9/10

CHARACTER
All the characters have a unique personality which I enjoyed. The father all being childish and protective while the son is curious and all. Every character is different.
8/10

Summing it up, it's a korean manga you must check out along with Crepuscule (Yamchi) though they are different but both involves demons and all. :D

=_= I suck at reviews haha.
