Eitaro Shidou
Father of Risa and Acting Principal of Seishū, he is the one responsible for bringing in Coach Daimon. Like his daughter, he is only concerned with the prestige that comes with Kōshien, having no interest in baseball itself. After Daimon’s team loses to the prefabs, he is unceremoniously transferred by Chairman Ōkubo following revelations of fiscal mismanagement.
