Berwald is a tall man with short, shaggy platinum blonde hair and turquoise eyes. He also wears thin, rectangular glasses. He had a distinctive stare that others perceive as menacing. He is silent and difficult to understand. He is quite playful but it’s rarely shown because of his intimidating aura. He shares a small fluffy puppy who’s a girl called hanatamago with Tino who they found in their shared backyard. Berwald actually has a crush on Tino, and struggles to think of what to say and expressing his feelings not just around him.
