A beautiful physical education teacher, Mahjong, encouraged his teachers at a school and was annoyed by the correction of the poor students in charge. Not only did he not listen to what he said as many times as he could be careful, but he was too patient with his mahjong squirrel and seemed to jump into the mahjong. One day, when he went back to the health room where no one was in class, Masubu, who had been calling back the defectives, was attacked by a group of excited people.
