But Blaz hasn’t come to help Staz unlock the secrets of The Book of Human Resurrection. Instead, he’s come to release Staz’s true vampire powers, the same magic Blaz sealed away years ago by putting a bullet through his little brother’s heart. Staz’s strength is needed to conquer a terrible threat that has appeared in the Demon World, and once again Staz finds himself a pawn in his brother’s game. Unless he confronts this terror, the secrets of his brother’s book will remain a mystery and Fuyumi will remain a ghost—if she doesn’t disappear entirely first! less

When Fuyumi is captured, Staz and the others split up to try to locate the missing girl. Bell's space-bending spying, Liz's crystal ball, and Staz's old-fashioned detective work lead them to their culprit: Bell's younger brother?! Like his sister, Knell has dimension-warping abilities, which allowed him to sneak Fuyumi away right from under her protector's nose. Caught between family and friends, will Bell help Fuyumi return to Staz, or will she plant herself firmly between them?!

Unwilling to let anyone just waltz away with her little girl, Neyn sends Team Fearless - a crew of vampire slayers - after Staz and Fuyumi as they make their way to Demon World South. Team Fearless has never actually taken down a vampire, but they're looking to make good on their name and "save" Fuyumi... But for a hostage, the girl seems awfully eager to stay at the Staz's side... Has she fallen for the vampire's charms...or just for his blood?!

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?!

With Akim threatening the Demon World, territory bosses Wolf and Staz must put their heads together with the local authorities to find a way to stop the piecemeal madman. Even working together, they're as short on ideas as they are on time! Akim's minions, cobbled together from the most dangerous bits and pieces of defeated demons, are proving to be more than a match for any who dare stand against them... moreWith Akim threatening the Demon World, territory bosses Wolf and Staz must put their heads together with the local authorities to find a way to stop the piecemeal madman. Even working together, they're as short on ideas as they are on time! Akim's minions, cobbled together from the most dangerous bits and pieces of defeated demons, are proving to be more than a match for any who dare stand against them. Saving Fuyumi may have to wait on the backburner for a while--Staz has to save the Demon World first! less

As the showdown with Akim draws nigh, have Staz and Wolf trained hard enough to make a difference in the coming battle? Would their strength even matter if the Blacklisted actually take the stage, or will Demon World's most notorious villains eradicate one another before the games even begin? And of course, all of this may be a moot point if Braz's scheming pays off...The showdown is on the horizon, but is Akim just too powerful now for anyone to have even a prayer of surviving...?

The final showdown starts off with a bang and a boom! Can the Blacklisted fight their way through Akim's loyal minions to reach the king himself? Will Braz's "poison" be enough to defeat Grimm once and for all? Everyone's giving it everything they've got--but it still might not be enough! All of Staz's training could never have prepared him for this... How do you stop limitless power? Just when all seems lost, a new challenger appears...!

It all comes down to this--two insanely powerful hybrids duking it out for the fate of the Demon World. Herrschaft Grimm, first king of the Demon World, versus Fuyumi Yanagi, the little ghost who could. With all of the strength of their friends behind them, can Fuyumi and Staz save the day? Find out in the FINAL VOLUME of Blood Lad!
