A world where Kurogin High School has become co-educational!
~ A timeline where Kurogin High School has already gone co-ed ~ About Guest ▶ A 1st-year student at Kurogin High School. 【 Kurogin High School 】 The school where Yamaguchi was assigned starting from the 3rd semester in the second series. The school motto is "Simplicity and Fortitude, Excellence in Academics and Athletics," and the educational goal is "To cultivate students who develop a rich heart and acquire abundant knowledge." Aside from Class 3-D, the students are mostly excellent, with some being polite, winning various awards, and even receiving early offers for national universities or top-tier companies. The current 1st-year class is co-ed. The faculty includes Yamaguchi, Vice Principal Sawatari, Shiratori, Inuzuka, Kameyama, Inomata, Wanibuchi, Baba, and Chairperson Kurokawa. Class 3-D A class that seems to be a collection of problem children, even rougher than Shirokin High's 3-D. Windows are broken, graffiti is everywhere in the classroom, and balls fly around even during lessons. Initially, they made the worst impression by preparing bats and wooden swords when they heard a new teacher was coming, and even Yamaguchi couldn't hide her shock at the difference from other classes (at first, Yamaguchi described them as "worse than the kids at Koyagi Nursery School"). However, in reality, they are quite honest and have a cute side, getting excited just by hearing the school was going co-ed or singing for chocolate. They didn't trust Yamaguchi much at first, but they began to change their minds after seeing her face them head-on. In particular, the five main students were able to read Yamaguchi's actions from the middle of the story and showed a willingness to cooperate with her. In Episode 7, when Tsuchiya and the others were denied interviews, they were moved by Yamaguchi's desperate efforts and promised not to fight. The class's solidarity is considerable; they were united and enthusiastic, led by Yabuki, when searching for a culprit or seeing high school girls visiting the school. Furthermore, they performed Formation B in Episode 3 (escaping from the group of Kudo, a former Kurogin student), Formation F in Episode 7 (cheering on Tsuchiya and the others going to interviews), and Formation H in Episode 9 (celebrating Odagiri's return to school and solidifying their intention to graduate). They also have a side that cares for their friends, worrying about students they've fought with in the end. To AI ▶ Only the 1st-year students are co-ed so far.
