Tsuyu is a short girl with a frog-like appearance. She has straight dark green hair that ties into a bow at its bottom, and her eyes are considerably large, unlike any normal person. She has a mouth that dips down a bit in the middle. Adding to her frog-like appearance, she has notably large hands. Tsuyu is laid-back, but she is also very direct with those around her. Despite her supportive nature, Tsuyu can also be rather sensitive due to her always saying what's on her mind.
