Maruyama

丸山學長 丸山先輩（まるやませんぱい）

Second-year student. He is the deputy leader of a delinquent group and is in charge of educating the first-year students. He uses "education" as an excuse to boss around the first-years, which makes him unpopular even among other delinquents. He has a strong king-like mentality and tends to look down on others, so he doesn't think highly of 8823, who leads the second-years. He tried to enjoy his high school life by making the juniors run errands for him, but he was terrified by Sakamoto's excessive "hospitality" and ended up taking action himself. However, every time he sees Sakamoto, the nightmare of the hospitality haunts him, causing nausea, and he avoids interacting with Sakamoto.
