Story: 7
The story is good. There are some plots that i though Yuuki Kodama could of focused on. For example, at the beginning it explains that there are bosses who control different regions & fight to keep control. After a few resolutions about it. Its not exerted further & moves on to different plots. Some of those plots are used the same way so its kind of a wasted potential. But other than that its reasonably good.
Art: 8
The art is very good. Not as detailed but it has a very clean and vanilla feel to it. Everyone looks different enough to depict who is who.
Character: 7
The cast is good. Personally my favorites being Staz & Braz. Staz displays more personality and is more reckless. While his brother shows more intellect and kinda has a deadpan manner of humor. The rest have a certain..genericness to them.
Enjoyment: 9
The enjoyment is great! I had a lot of fun seeing the struggles & misunderstandings between the characters. The fights are well done.

Overall: 8
I think Blood Lad is very good. There aren't many fun vampire/Demon World manga series like Blood Lad. I recommend it. 👍
