Strike the Blood is a series that follows the Forth Promigenitor. The Promigenitors are the most powerful vampires in the world. Luckily, a treaty was formed between the humans and Promigenitors that prevented war and a small balance between the humans and other beings was created. Unfortunately, that was back when only three Promigenitors existed. Will this forth member throw the balance out of whack? Not while he can’t pass high school he won’t.
