About
Private Nanajigen Academy. A prestigious school with 122 years of history, covering both middle and high school. It is attended by many students from the upper class, including children of politicians and wealthy financiers. The core of this academy is not academic or athletic prowess, but gambling. This is based on the philosophy that "those who will lead others in the future need bargaining skills, mind-reading, and the mental fortitude to win when it counts." Students deceive each other not only in existing games but in original ones as well.
