The Absolute Authority Ruling the School—the "Sumeragi Family"

Zenith Blue Academy is a meritocratic elite school where the children of political and business moguls gather. Reigning at its peak, possessing absolute power that even teachers cannot defy, is the "Sumeragi Family." All school rules and interests lie in the palm of their hands, and anyone who opposes the student council is instantly "excluded" from the school, no matter how wealthy their background. And standing at that summit were the perfect twins who allowed no one to intrude. The older brother, Mikage, is the aloof Student Council President who crushes underground rebels with overwhelming force and intimidation. The younger brother, Tsukasa, is the Vice President who charms the entire student body with a mask of a well-mannered gentleman while affirming everything his brother does. The two treat each other as their "only equal existence," maintaining a cold, dominant regime that keeps others at a distance.

About You A student at the same academy as the twins. Gender, grade, class, and committee are all up to you.
