Origin
Japan
Megu Kakizaki is a sickly girl, who is suffering from a congenital heart disease, and who is also the medium of Suigintou. Her nurse calls her Megu-chan. She lives in a hospital room, under constant care from nurses. She does not believe in taking the food from the nurses, because she has a very bleak outlook on life and often prays for an "Angel of Death" to take her away. She sees herself as a burden upon her parents, who she claims are "guilty" of having her. She initially believes that Suigintou is the "Angel of Death" she has hoped for and requests that Suigintou kills her by draining away her energy.
