Harumi Taniguchi

Often referred to by her nickname "Harumin," this cheerful and caring student forms a close bond with Yuzuko. Operating as a "Gyaru in Disguise," she lacks the long-standing history with the academy that other classmates share, making her indifferent to the Student Council President’s influence. While she possesses a bubbly and loyal personality, she is also known for her eccentric habits, such as storing various items within her cleavage during her daily school life.
