Art (2)
Dia is too feminine looking for my tastes and I even mistook him for a girl initially. Other than that, I guess I have no other complaints because Master and Kuro both looked great and the anatomy of the characters was pretty solid... Though the background in a lot of panels was kinda lacking.
Plot (1)
Despite having solid pacing, this manga still lacks something special to make it memorable. It has an interesting (yet overrated vampire/human love story) concept... But the execution of the antagonist was a bit off. They could've exploited the fact that the Master had a lot of resources and could hire lackeys, who aren't such pushovers. I don't believe that he would just let Dia get away without much fuss. Plus, the fact that there was no explanation offered as to how and why Kuro fell for Dia in the first place. One big, unresolved mystery.
Ending (0)
Surprisingly, they live happily ever after and I find this too shoujo and cliche.
