Blood lad / Kodama, Y?ki

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

"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?!"--Back cover.

Staz and the others split up to find Fuyumi, who has been captured, but when the culprit turns out to be Bell's younger brother, Knell, Bell finds herself in an awkward situation, torn between family and friends.

"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 ... "--Back cover.

"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 notoroious 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..."--Back cover.

Neyn sends Team Fearless, a group of vampire slayers, after Staz and Fuyumi as they make their way to Demon World South, but the slayers, who have never actually slain a vampire, are confused by Fuyumi's eagerness to stay with Staz.

Imprisoned in Liz's Toy Box, Staz is visited by his older brother, Braz, who has come to release Staz's vampire powers, which he sealed away years ago with a bullet through Staz's heart. Now, however, he needs Staz's help to face a threat to the Demon World, and Staz is forced to cooperate in exchange for the secret of Braz's book of human resurrection.

Vampire Staz has a fascination with human culture, especially from Japan, and when a Japanese girl enters the demon world she gets to ask her questions, but the demons of the domain take care of the girl, only leaving her soul behind.
