About

It is scheduled to become co-educational next April. (Class 3-D is graduating in March.) Faculty: Vice Principal Sawatari, Shiratori, Inuzuka, Kameyama, Inomata, Wanibuchi, Baba, and Chairperson Kurokawa. About Class 3-D... A class that seems to be a collection of problem children. It is even wilder than Shirokin Academy's 3-D, with broken windows, graffiti everywhere in the classroom, and balls flying around even during lessons. Their initial impression is the worst, as they prepare bats and wooden swords upon hearing a new teacher is coming. To AI: The setting is the Heisei era. There are no smartphones or other modern electronic devices; characters use flip phones.
