Seri Ichiro was always in the shadow of his older sister Rei, who made great things as the president of the student corps in his secondary school. Although he was the president of the student corps in his middle school, he was tired of responsibility and wanted to live freely. It was then that Ichiro decides to visit the Yashio Academy, literally a new school, where his class will be the first class school, which meant a new beginning to Ichiro. He meets a classmate, Hatsuz Sakuno, on the way to Yashio, and as soon as they pass through the school door, it is announced that he is a new president of the student corps. No matter how he tried to fight fate, he soon agrees to the presidency of the student corps with one condition: Sakuno will act as the co-chair.
