At the beginning she was nervous because of seemingly uselessness of her ability; constant blames from Cara made her character timid. She was afraid Roland would expel her from the town and was reluctant to accept from him the same treatment as for the other witches, who unlike her greatly contributed to him.
Despite the fact that she was prohibited to use her magic and thus suffered the most from the magic bite, she survived her Awakening day, which implies a strong willpower.
Despite being adult she acts less mature compared to the younger Lily. After Roland taught her how to use her powers to make electricity, she became more confident and outgoing - sometimes leading a group of witches out to solve a mystery. She is still prone to anxiety, however, as after Sharon awakens and it is revealed she is able to also use electricity, she becomes anxious that Sharon will replace her and she will lose her spot in the Witch's Union.
In Witch Cooperation Association she had no use for her ability and completed some chores. She was blamed by Cara for inconvenience caused by her ability and was prohibited to use it in the camp.
Mystery Moon was among the few who successfully returned to the camp after failed journey to Holy Montain. When Scroll offered to Leaf lead the remnant members of Witch Cooperation Association, the latter refused and explained she would try luck in Border Town. If she won't return Scroll should guide the rest to the south or across straits.
Awaiting group was greeted by Nightingale and Lightning and brought to the castle where a feast was arranged for them. After that Hummingbird showed her abilities and was given room on the second floor. At night witches gathered in Wendy's room and discussed their past and future, also wondering the reason behind Roland's kindness. Next morning she signed a contract with him.
Mystery Moon's magic is attaching type. The attaching process is very slow, to magnetize a stone of a cubic foot she needed half a day.
Awakening: Magnetizing of metal objects.
Adulthood: Magnetizing of any objects.
Evolution: She learned the connection between magnetizm and electricity and can now alter objects to quickly switching poles. This can be used as generator for electricity.
Lily often acts as a big sister for Mystery Moon despite the fact that Lily is younger. Lily will often bully Mystery Moon, but never fails to support her when she is anxious.
