Even after death, life is full of paperwork and criminals. Tsuzuki Asato is a 26-year-old, happy-go-lucky, and dorky shinigami (god of death) whose job is to make sure that those who are dead remain dead and stay in their proper realms. Even though he has had this job for over 70 years, he is in the worst division with horrible pay. He also has a knack for not keeping partners (since shinigami work in pairs), but now he seems to have one that will stick around; stubborn, smart-mouthed, serious, and defensive 16-year-old Kurosaki Hisoka. With each case they investigate, they come closer to the conspiracies of the serial killer Dr. Muraki Kazutaka. Tsuzuki's relationship with Hisoka is growing stronger and closer... but there is a dark past to how Tsuzuki died that will not give him peace.
