Hyakkaou Academy- an ordinary school in many aspects, yet extraordinary in one: gambling. Gambling was an enjoyable pastime for many students- and for a long time that's all it was: a rich kid game. Academics, athletic achievements… they were the real determiners as to your position in the hierarchy.
At the top of the hierarchy sits the President, a third year, seemingly untouchable, yet is toppled by new student extraordinaire, Momobami Kirari- along with her best friend Yomozuki Runa.
On the other end of the spectrum sits Miboumi Aoi, an ambitious second-year hoping to nab the Presidency for himself- however, the new girl's interference throws a wrench in his plans.
His fiancée, Miharutaki Sakura, is faring slightly better- the only catch to her life being her eternal rival: a certain flirtatious red-eyed sadist named Juraku Sachiko.
A geeky girl named Igarashi Sayaka takes an unexpected leap towards power, while her best friend Ikishima Midari is a helping hand in stirring up havoc in Hyakkaou.
What happens when you also throw in a certain masked girl, a nerd with glasses, a wannabe idol and a rich bitch into the mix?
Scandals, drama, gambling, gayness and aquariums ensue.
AKA the Hyakkaou Student Council origin story nobody asked for.
