Momo is a shinigami who leads deceased souls to the other side. She's dressed in all white and has long white hair. She carries with her a large scythe and an ID card (A-100100) to facilitate her identification as a shinigami. She tries to ease the suffering of the people she encounters—whether they be living or already dead—by enabling them to live their lives to the fullest, or at least to transfer to heaven without regrets (in contrast to other shinigami). She cries a lot, saying she cries for the dead because they no longer can. Accompanying her is a talking black cat familiar named [Daniel](https://anilist.co/character/6444/Daniel). The living frequently hear the ringing of Daniel's bell when Momo and Daniel are nearby.

A girl wrapped in white, her name is Momo...in her hand lies a blunt yet shiny scythe. By her side is a winged black cat by the name of Daniel. Carrying the souls of humans, the girl's existence parallels to that of a "Death God" or "Shinigami". At the instant when this white Death God touches the hearts of humans, the world is filled with kindness and grief...

A Shinigami girl in white, unlike other Shinigami... A Shinigami girl meddling with humans, even those not to die, unlike other Shinigami... 
Shinigami A#100100 or Momo not only leads the souls of the deceased to the other world, but also leads the living to a better life, helping them overcome death...

In the darkness stands a girl draped in pure white. Don't let her innocent appearance fool you; her hands grip a glistening scythe. Momo is the dark messenger of death who, along with her wisecracking cat named Daniel, is tasked with releasing humans from their mortal bonds and delivering their souls to the great beyond. First encounters with Momo always end in farewells.
