What a strange little comic! I was intrigued to read this because on reddit someone was like: "What's that one book, I think it was for kids, but it had some really graphic gore and violence in it?" and when the answer was a title like Little Vampire Does Kung Fu I had to see if my library system had it (they do)!
It's a very silly comic, the words are small and the pictures and panels tightly packed in, and I'm pretty sure boys aged 9 and up would love it!

The gore... not too explicit and gorey but a kid would get a kick out of it.

I think my biggest complaint is that the title is misleading. Little Vampire DOESN'T know kung fu! And it's the little boy Michael who needs to learn it! Little vampire doesn't even learn kung fu!
