Ai Enma

Personality: Little is known about her personality, but it is revealed that Ai was buried alive. She had only one friend who, in the end, causes her more emotional damage. Outwardly, she is very stoic and an introvert, often bearing an expressionless face. She seems to be a wise and calm person, however, with a deep-rooted sense of justice, and she seems to be sweet, beneath the "unfeeling" exterior.
