The insurrection stirring beneath the Hyakkaou Academy’s Great Bloom Festival has finally reached a boiling point as Aoi issues his orders for the big day…! However, that doesn’t mean Nagi and Soutarou want to give up on Mary Saotome, and the game set up at the Literary Club might be too simple to stop them from gambling her into the Full-Bloom Society…That is, unless the student council gets involved!

Festive cheer and slot machines take over the academy during the Great Bloom Festival, a week-long excuse for students to gamble to their heart's desire. As Mary scours the festival grounds for a worthwhile den, Tsuzura and Yukimi are forced to partake in a stripping game with yet another Full-Bloom member, the risqué photographer Eneru Rokujou! Can the two protect their beloved club in Mary's absence, or will they lose it-along with their clothes?!

As the academy overflows with the heat and cheer of the Great Bloom Festival, Aoi is ready to put his plan against the student council in motion. Meanwhile, Mary's search for the perfect gambling den ends when Kurumi introduces her to the music club. Her opponent, Nadeshiko Rurichou, has a fine game prepared, but more importantly, is Kurumi someone Mary can really trust...?

Will Mary enter the Full-Bloom Society or will she become Juraku's pet? As Mary struggles with this choice, an unlikely ally appears!

Peace and quiet return to Mary as the girls resume operations at the den, but will such a life be enough for the budding star? When an unwelcome visit from Juraku-head of the Public Morals Committee, a.k.a. sadism incarnate-turns into a high stakes gamble, Mary must hold her ground lest she lose herself and her sanity...

After rejecting an exclusive love call from the student council nice guy, gambling hotshot Mary Saotome has been attracting all sorts of unwanted attention-especially from her classmate and hater Kokoro Aiura, who tries to sabotage her every chance she gets. Can Mary beat the anti-fan at her own game and end the petty bullying once and for all?!

After losing her hard-earned profits to student council member Aoi Mibuomi, a penniless Mary is given a chance to take it all back on just one condition: She must team up with Aoi to oust the student council president! But in order to do so, she needs to first prove her skills in one of the academy's most popular events-the Coupling Party! Will Mary be able to use her gambling prowess to survive this dirty game of cupid?
