宇佐美 ハル

A girl who transferred into Kyousuke's class in search of clues on her hunt for Maou. When the time calls for it, she's a great detective with sharp reasoning. Although she is highly intelligent, her odd behaviour and speech causes confusion in those around her. She has a cute side since she loves penguins and makes her own penguin costumes. She comes to rely on Kyousuke in her investigations.
