The eldest son of Cecilie. From the beginning, Gwendal has objections to Yuri becoming the Maoh. He is a skilled tactician and is capable of using earth magic and can cast barriers. When not otherwise busy, Gwendal indulges in his hobby of knitting and sewing but often his creatures look nothing like what they're supposed to (for example a bear got mistaken for a black pig). He is also quite fond of cute objects such as the dolphin keychain (Bandou-kun) Yuri received at the dolphin show and later gave to him. His childhood best friend is Anissina von Karbelnikoff, an inventor who often tests out her inventions on him, much to his displeasure. Gwendal's left eye is a key to one of the four Forbidden Boxes, the "End of the Earth". Gwendal is a tough guy except when it comes to his childhood friend, Anissina. He is afraid of her and often hides from her so he can prevent being used in one of her crazy experiments. He is the commander of the demon army and often comes with reinforcements when Yuri finds himself in big trouble. He is also the one who does the paperwork and essentially runs the kingdom for Yuri.(Wiki).
