Beidou is a tall, muscular woman with long brown hair and ruby red eyes. She wears a short sleeveless red dress with slits that reveal her thighs, black thigh high boots, and black elbow length fingerless gloves. She also wears a white fur collar, a red eye patch on her left eye, a bronze hairpin with a cyan tassel, and one bronze earring with a cyan tassel on her left ear. Beidou wields a claymore, and has slain the sea leviathan Haishan. She's forthright, easy-going, and kind.
