Misha is an angel-in-training visiting Earth to study for her 'Angel's License'.
Misha is cheerful and very naive. She is very attached to Kotarou, her neighbor. She often (without acknowledging it) annoys him by following him and hoping on him. She occasionally doesn't understand human ideals, and doesn't understand the concept of personal boundaries very well.
Later, she ironically becomes best friends with Shia, an uncommonly kind demon apprentice. Despite their statues as traditional enemies, they remain friends throughout the entire story.
