Momo is a Shinigami, a God of Death. She even has a license—#A-100100—and the Reaper's trademark, a scythe. Nonetheless she dresses completely in white, and has a very gentle and caring personality. Because of this she does not just stop at fulfilling her duty to carry away souls, but instead tries to enable all of her "clients" to live their life to the fullest, or at least go to heaven without regrets. Therefore she tends to meddle in the affairs of the living, sometimes subtle, sometimes less so.
