ABOUT Gwendal is a very quiet person, so there isn't much that we know about him. His name is Gwendal von Walde (or von Voltaire, depending on the translation). We know that he's a mazoku, with his own [kickass] castle, which his childhood friend, Anissina, I assume, lives with him. Gwendal tends to be the guinea pig for most of her experiments. He has two brothers, Wolfram and Konrad, that are shared from his mother, the former Maou, Cecilie. Gwendal also has earth-based magic, while his brother, Wolfram, has fire-based. Gwendal seemingly enjoys cats, laughing when surrounded by questionable fumes with Günter, war, and knitting. Gwendal is also named after a Olympic champion iceskater. Who likes cats.
