Tamaru, a demon who is several thousand years old. He's considered powerful demon. He is very generous with his praise when it comes to her master. He doesn't try too hard to protect her or take care of her, but he always praises her for her good work sincerely. He likes being her familiar and he doesn't understand why it seems strange to her. Calm, naive, cheerful, just hanging around, not much use from him. Not obsessed or in love, but rather curious and interested. Can transform into a crow
