By the request of Goro, Kimihoshi changed Morilin's name to "Kurumi."

* Age: 17 (First Season), 18 (Second Season) * Birthday: September 15 * Western Zodiac Sign: Virgo Mika is extroverted and hyperactive. Her over the top antics usually result in her being yelled at by Ayumi and Akane (rabbits have a history of rivalry with turtles and foxes). When she was a rabbit, she died of loneliness, which may account for her current personality of being an attention seeker, possibly gaining Autophobia; a fear of loneliness. Mika is in the Senior rank. Her name means new moon, alluding to myth of the rabbit of the moon. Her color image is orange. Unlike most of the other angels, she is very clearly romantically attracted to Goro. Her hairstyle represents a rabbit's ears. (Source: Wikipedia)
