Fourth Mikado City Middle School (三門 市立 第四 中学校, Mikado-shiritsu Daiyon Chūgakkō ?) is a middle school located in Mikado City near the mountains. It is farthest from the damage done by neighbors in the First Large-Scale Invasion, so the students have less of a fear of neighbors. It is to the far Northwest of the area Tsukihiko Amō turned into a vacant lot in the large scale invasion. It is far from the city center, but there are students still hung up on 'fashion' and 'individuality'.[1]
