The stories happened in China around post-Qing period although the hair styles of the men did not fit well.

Son, the protagonist, was a free writer who deeply loved a woman he called 'elder sister' Shue but she was dead. Fu, an apparently young, skilful but cunning Taoist priest, re-animated Shue and used her as a zombie body guard... In order to acquire the method of full resurrection of Shue, Son became an apprentice of Fu and promised to help Fu with various unreasonable tasks. After that Son met different priests and necromancy practitioners, and he even visited the other sides of the world. Most of the stories are associated with Chinese necromancy and folklore and that is probably why it is called Necrolog.

"This is a story about two sisters: Shizuru is a high school student who is able to see ghosts while her younger sister, Mizuki, is haunted by these apparitions. Frustrated by their abilities, their parents decided to entrust the sisters into the care of their grandparents who live in the countryside. As they adapt to life in the countryside, Shizuru and Mizuki begin to learn about the importance of coexisting nature with these apparitions."
