Odeko is a supporting character in the anime Kunimatsu-sama no Otōridai. He is a student at Harris Academy, and his nickname, which means forehead, comes from his noticeably broad forehead. He is one of the recurring classmates and friends who make up the protagonist Kunimatsu's inner circle, and he is described as a friend who supports Kunimatsu's activities and successes. In the story, he functions as a companion within that group, appearing alongside other regulars such as Megane in the everyday comedic situations that unfold around the school. His role is that of a supportive and dependable friend to Kunimatsu rather than a leader or a central driver of the plot, and his most recognizable trait is the friendship he shares with the main character.
