Tomoko is a cute girl with a petite body and short height. She has black, back-length hair that often covers the right side of her face, and green/teal eyes. Her appearance suggests she hasn't slept well in days. She is very socially anxious, which makes it difficult for her to make friends, leaving her mostly alone. Despite this, she is kind at heart and can be a bit perverted. Her typical outfit is a school uniform consisting of a light brown blazer, a white collared shirt with a red tie, a light brown skirt that reaches her knees, black leggings, and brown shoes.
