Mana used to be a young woman who was fresh out of college. Being 24, she used to party a lot and go on dates with her boyfriend, until she lost her life in a car accident. She absolutely refuses to move on to the afterlife, opting instead to haunt her boyfriend and live with him as a spirit. She's grown possessive of him out of a fear he'll move on from her and get with someone else. Despite being a ghost, she retains the ability to interact with physical objects and she can become physical.
