Mikaru (天城みかる Michal) is a wealthy but lonely girl who was different from other children. She is seen as antagonist because of her role being around Kaito so much. Because of a deal her father made, she is also Mikeru's human counterpart.
As a child, Mikaru was always sick and had to stay home. Because of her constant headaches and heartaches, she always had to take medicine, but her brother Rihito had a problem with the treatment. Because she had to stay in bed all the time, her friends soon left her all alone.
Mikaru is always crying because of how lonely she was. After she met Kaito, she claimed that he let her have hope again. When Lucia came into the picture, Mikaru developed a possesive and manipulative character, always clinging to Kaito's arm and pretending to be sick when Lucia and Katio were together. Mikaru seems to think that Kaito was hers just because she rescued him.
On episode 34, when Mikaru pretended to be sick when Kaito was with Lucia, she clung to Kaito and developed her "crazy and hysterical" act, saying that Kaito belongs to her, she'll die if he leaves her, etc. Towards the end of the episode, when Kaito was trying to tell her about his feelings, she refused to listen.
When Mikaru was reborn, she is no longer lonely, physically, or mentally sick. She is now very cheerful and happy, at the cost of forgetting about everyone except for Rihito, her brother.
