Casts

• Keiko Kitagawa as Momoko Hasegawa (長谷川桃子, Hasegawa Momoko?)

Momoko is a young salary woman working for Little Angel, a funeral services provider that handles a variety of cases. Despite having a low-paying job and living in a rundown apartment, she is actually the daughter of a wealthy family in the hospital business. She has a special ability to travel back in time, which she acquired in a traffic accident at a young age. This ability only becomes fully developed after she is transferred to Little Angel, as it is revealed that touching mementos which hold great significance to the deceased would activate her time-travel abilities. Throughout the series, she attempts to use this ability to travel back in time to prevent the deaths of the would-be deceased persons with unfinished business. She is obsessed with muscles.

• Shōsuke Tanihara as Shoutarou Otomo (大友将太郎, Otomo Shoutarou?)

A senior colleague of Momoko in Little Angel. Shoutarou may be cruel towards Momoko sometimes, but has always come to Momoko's aid, often under threat by Momoko to reveal his secrets. He is especially interested in foreign ladies gaijin, a weakness exploited by Momoko to get him into helping her. He has a variety of skills, including picking locks, stealth infiltration, deception, and intelligence gathering; Momoko comments that he should "become a professional criminal" rather than being in the funeral business.
