Seiha Shiunji

Seiha Shiunji is the second oldest Shiunji sibling, second only to her older sister Banri Shiunji. Arguably the smartest Shiunji sibling, Seiha is the top ranking student in their entire school, as well as the president of the science club. She is so book smart that she can come off as cold and distant, tackling almost every problem as logically as possible. At times, this logical approach to everything can go to extremes and make the people around her uncomfortable, but she doesn't see to notice this.
