Descendants Of Darkness, Vol. 3

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?
The business of death is never simple. Booked on a cruise ship headed for Hong Kong, Asato Tsuzuki finds himself entangled in yet another one of Dr. Muraki's nefarious schemes.
There's a killer on the loose and corpses are piling up at an alarming rate. Tsuzuki immediately suspects his old nemesis is somehow involved. But his theory falls apart when Muraki unexpectedly becomes one of the murderer's victims.
