Demon Lord Tasogare

He kidnapped Syalis in her sleep, so he has hardly ever seen her awake and has never had a proper conversation with her. He is always thinking of ways to make the hero get to him and gets worried if he is going to lose, he even puts weapons and tools to make the hero's quest easier. Apart from that he is a good leader for the demons of the castle, but even he can't go against Princess Syalis, and is shown to care for her to a certain point.
