The Stray Dog (野良犬 Norainu ) wanders into the courtyard of the school that Yuichi Aizawa and the others attend, but it is scared off by Mai, who can later be seen feeding the dog after Yuichi and Sayuri Kurata chase after her. Sayuri then explains to Yuichi that the dog had been there before, and that the principal and Kuze's threats for the expulsion of Mai were nothing new to the school.
