Biwaki is a Japanese girl with incredibly pale skin, a white nightgown, and a wreath of pink and red flowers atop her head. She is equipped with a biwa tht has two shapes on its body that resemble crescent moons. Her hair is black, and her face is noticeably maniacal-her eyes and eye sockets are dark and deep, and her miniscule pupils are completely white. Biwaki's smile is enormous, she bears yellow teeth and her gum line is exposed. Biwaki's mouth and eyes drip black liquid, which is a common feature amongst Kintoru's puppets.
Before Biwaki was cursed, she was a young girl with a rounded face, and pale skin, and has black hair, which is neatly arranged in a bun, with a few strands falling gently across her face as bangs. Atop her head sat light pink, rosy flowers which were wreathed into a flower crown, her attire was a paper white long-sleeved dress, the collar had a crew collar style.
