Students of the prestigious Tokyo Metropolitan Advanced Nurturing High School are given remarkable freedom—if they can win, barter, or save enough points to work their way up the ranks! After getting in a fight with students from Clas* C, Sudou is on the verge of expulsion. Ayan*kouji and Horikita may have found a witness in Clas* D’s Sakura, but she’s reluctant to make waves and get involved. And even if she did, would anyone trust the word of a Clas* D student? Meanwhile, Ayan*kouji and the others discover additional ways to earn points outside of test scores. But will it be enough to buy their way out of Clas* D? Or is the system truly rigged against them?
