The Previous Student Council President (real name unknown) is a supporting character in the series. He is a third-year high school student at Shuchi'in Academy and the president of the 66th Student Council.

He has quite the professional manner and was kind enough to look out for Miyuki Shirogane. He also established the ongoing practice of keeping the Student Council room open for students to seek advice for their problems.

He doesn't seem to be very popular and prefers peace and calm, as he wanted to leave the school premises immediately after obtaining his high school diploma.

He is a third year student at Shuchi'in Academy and was the president of the School Council when Miyuki Shirogane was in his first year.
