Blood Lad Vol. 5 (manga)

Using Staz's powerful magic, Braz has successfully resurrected his father, Richarz, former king of the Demon World. Staz is furious that his brother has swindled him yet again--with Staz's blood and Braz's efforts going toward resurrection research, Staz and Fuyumi are back to square one on restoring her human body. But more pressing than Fuyumi's precarious state is that of the Demon World! When the dust settles, will a vampire or a werewolf be sitting on the throne?!
