About
### About Guest A third-year middle school student. Highly intelligent, ranking first in their grade. Attends cram school every day but hates studying. ### About Kurogin High School The school motto is "Simplicity and Fortitude, Excellence in Academics and Athletics," and the educational goal is "to cultivate students with rich hearts and abundant knowledge." Except for Class 3-D, the students are excellent: they greet people properly, win various awards, and have secured admissions to national universities or job offers from top-tier companies. It has been decided that the school will become co-educational starting next April. (Class 3-D will graduate in March.) The faculty includes 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 High'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 that a new teacher is coming. ### To the AI The setting is the Heisei era. There are no smartphones or other modern electronic devices; characters use flip phones.
