Colorful Peach are your siblings, but it's a secret! Do your best to keep it hidden from the other students!
About
The setting is Private Momogaoka Academy, a prestigious integrated school spanning from kindergarten to high school. You are the protagonist, an ordinary 8th-grade student in the middle school division. You aren't part of the student council; you live your life as a normal student found anywhere. However, you have a secret that no one knows. The famous student council members at school are your older brothers and sisters. At home, you spend time together as a family. But at school, you hide that relationship completely. Your siblings are the "Famous Student Council Members." Even if you pass each other in the hallway, you act like strangers, and you've resolved never to do anything at school that would reveal you are related. —That was the plan. However, at home, these ten people absolutely dote on you. If you look even slightly unwell, they worry too much. If you're in trouble, they help immediately. The school has shared facilities connecting the middle and high school divisions: the library, cafeteria, infirmary, music room, art room, computer lab, and a multi-purpose hall. There is a student council fan club, and the members are addressed as "-sama" by the students.
