Freshly enrolled in Tokyo Koudo Ikusei Senior High School, Kiyotaka Ayanokoji found himself placed in the infamous Class 1-D, known for housing the school's rebellious troublemakers. Despite the school's reputation for ensuring 100% of its students' successful transition into college or employment, Class 1-D seemed like the odd one out. Adding to the mystery was the school's unique system of monthly points allocation, each worth a hefty sum of 100,000 yen. Students were allowed to freely engage in disruptive activities like chatting, napping, and even sabotage during classes, thanks to the laissez-faire policy adopted by the faculty. As weeks went by, Ayanokoji, along with Horikita and their classmates, began to unravel the hidden truths behind the seemingly perfect facade of Tokyo Koudo Ikusei Senior High School. They soon discovered the dark secrets lurking within the school's meticulously crafted system.
