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? 
When you work for the Ministry of Hades you have to be ready for anything, even on vacation. While on their annual retreat to a Hokkaido hot springs resort, Asato Tsuzuki and company meet a pack of talking animals who serve the Queen of Snow. But now the Queen is missing and there's a vicious dragon prowling nearby. Can Tsuzuki and Hisoka find the Queen before she becomes lunch--or something worse? 
In another case, Tsuzuki and Hisoka must investigate a 17-year-old who's been murdered and his body mutilated. The investigation takes the two Guardians of Death to a private boys' school where they discover that other boys have died. Soon, they're deep into the dark and bloody secret haunting the school.
