Birthday: October 16
Blood type: A

Tadokoro is a loud, confident person with a personality as big as his stature. He is a proud sprinter and has no qualms about boasting when he wins. However, Tadokoro also has a softer side, exemplified by how much he cares about Teshima and Aoyagi. He often argues with Naruko, who is also loud and competitive. Though he seems imposing, Tadokoro also gets flustered in certain situations such as when Onoda convinced him to sing an anime song and when he encountered some cosplay maids in Akihabara.
