Synopsis
Momo is a shinigami (a Grim Reaper), the messenger of death. Unlike the scary dark cloaked man holding a sickle, she is draped in gleaming white—her gown, sickle, hair and all.

Accompanied by a black cat named Daniel, Momo takes up a mission to convey human souls to the Great Beyond. She appears before dying people and relieves them from their mortal fears, but she also comforts those who suffer the anguish of losing loved ones in tragedies.

Momo the Girl God of Death
An anime adaptation of the light novel aired for 6 Episodes between March 3, 2006 and April 7, 2006.
