Harumi Sakamoto

As Akira's older brother, this character was once a student at Fujimori and was widely recognized as "Sakamoto-sama" for his striking beauty. He reappears during the cultural festival to assist the student council with fundraising efforts, generally exuding a cool demeanor with a constant smile. However, this facade melts away when interacting with his younger brother, revealing a deeply emotional side that easily brings him to tears.
