He wears goggles and a red cape. Originally from Teikoku. The reason why he plays for Teikoku is for his sister, Haruna Otonashi. He was forced to win 3 constructive soccer championships in order to be with her again, so he decided not to contact her for 6 years, leading Otonashi to believe she gets in his way. After seeing Kageyama's wrongdoings, he and the rest of Teikoku quit. Eventually, Kidou joins Endo's team, changing his cape to blue but changes it back to red in the FFI arc.
