Descendents of darkness (a.k.a. Yami no Matsuei) concerns two Shinigami's (Gods of Death) the affable, sweet toothed Tsuzuki and his new, surly at times partner Hisoka. It is their jobs to guide lost souls to their judgment while at the same time confronting their own dark pasts, which seem to revolve around a rather handsome, silver haired doctor.
