Tomoko is a female of petite stature with large mauve eyes and chin-length dark green hair with bangs swept to one side. Her cheeks are shown as pink circles, although meant to be natural or cosmetic is unknown. She is polite, helpful and dedicated to the task at hand. In the OVA, she is seen wearing a brown skirt and a light green, long-sleeved graphic tee-shirt depicting a stylized bear. Over this is worn a pink haori trimmed with yellow and an image of Iwatobi-chan on the back. During the mascots' combat, she wears an Iwatobi-chan cap.

Story
In Tokyo, it's time for the annual High School Mascot Competition. Three students from Iwatobi High School are in town with the required life-sized Iwatobi-chan costume. They are excited, but distressed because the beak is missing. When Makoto runs into them and they learn of his Iwatobi history, he is manipulated into wearing the costume and competing in the sumo-style wrestling contest between mascots. Meanwhile, Haruka Nanase happens to find the missing beak when he accidentally steps on it while taking a walk. Realizing what it is, he heads to the contest venue where he meets the students and Makoto. There, he convinces a reluctant Makoto to defend his alma mater's honor, then stays to cheer him on to victory.
