The business of Death is never done. Asato Tsuzuki works as a Shinigami, or "Guardian o Death," in the Ministry of Hades. It's his duty to make sure that the souls of the dead reach the afterlife, but contrary ghosts and humanity's evils keep getting in the way of a job well done. With all these problem assignments, will he ever get a bonus...or will he be stuck paying back damages for all eternity?

Hisoka won't leave the Imaginary World until he has some Shiki spirits of his own. But strange "wormholes" keep ripping open the sky, threatening the end of the Imaginary World--and one sucks Hisoka right into the realm of the fearsome dragon Kurikara! How can Tsuzuki save his partner from the powerful Shiki he once failed to tame? And why are the other Shinigami investigating Hisoka's family back on Earth?
