Haschwalth is a tall, young-looking man with a thin build and long blonde hair, which descends past his shoulders, and blonde eyelashes.

 His usual attire is a variation of the Sternritter's typical white uniform, consisting of the order's signature hooded-cloak, a calf-length trench coat, dark green fur running down from his left collar to the front of the coat, a green belt with a golden belt buckle, along with white trousers and shoes.
