Need help remembering a series.
I read this series a while back, sometime around last year or two.
Anyways the story is about vampires. There was this kid, main character, who really like spiders. He had a best friend that was sort of crazy. The friend convinced him to go see the circus with him. The circus was full of magical creatures like two headed snakes, werewolves, and the most poisonous spider in the world.
His crazy friend actually went to the circus to try and become a vampire, he was rejected though.
So later the kid steals the spider from the show, and learns to tame it. But he accidentally lost control, and it poisons his crazy best friend. He makes a deal with the vampire that owns the spider. That if the kid becomes a vampire, his friend would be saved. When his crazy best friend finally wakes up and cured, he discovers that the kid became a vampire. He became so pissed because he wanted to be a vampire, and so diluted with the image of betrayal that he vows to hunt down all vampires. Or he vowed to hunt down the kid which became a vampire.
Through the story, vampires are not so bad of a sort. Also the manga was based on a book series. I really want to remember the name of this series, hope someone can help me.
