Tsuyu is a short girl with a slender build and notably large hands, giving her a frog-like appearance. Her frog-like traits are the least pronounced in her family. Tsuyu's dark sea-green hair is long, reaching her waist, tied at the bottom in a bow. She has two shoulder-length clumps framing her face and shorter bangs. She wears a white seifuku with dark blue cuffs, and skirt, paired with a red scarf, black knee-high socks, and brown shoes. She also wears a cyan collared scarf.
