von Wolfstadt, Klaus

Klaus von Wolfstadt, hailing from one of the nations within the "Western Alliance," has abandoned his military obligations to his country in order to serve as a knight to Taki Reizen. Reizen is the commander of the 15th division, "Rozen Maiden," whose nation maintains an alliance with "Eurote," an adversary of the Western Alliance.
He is also known as "Mad Dog" and is occasionally referred to by his subordinates as the commander's "Loyal Dog."
