Klaus Goldstein

Klaus is the most favorite ML of the user and reader named Annicca in Wizardess Heart. He is entitled as the "Emperor" for his charismatic, intelligent point of views in wizardry and magic, strict, rude, and mysterious behavior but if you get to know him, he is actually a gentle, sweet, and caring person. He is just afraid to show it due to personal reasons. He is also the elder brother of Elias.
