Story
"The Pyramid" is a powerful social ranking method since ancient times. At Saginomiya Private School, where the children of the upper class gather, it is an absolute caste system. The only way to win is to climb the pyramid! Sato Rei, an average boy, seems destined to be stuck in the lowest tier of the pyramid, doomed to spend the next three years being bullied by the rich and popular. The only way to survive is to move up to the S class. Suddenly, a beautiful, unfamiliar girl appears before him.
