Losing big to a member of the student council, Yumeko finds herself deeply in debt and cast down to the rank of "house pet" in the Hyakkaou Academy hierarchy. With her future hanging in the balance, the student council tournament may be Yumeko's only shot at redemption. Teaming up with former rival Mary, currently suffering the same sub-human indignity, Yumeko and her new partner are prepared to go all in for another shot at the high life. But will luck favor these ladies...?

Enduring the "Big Debt Settlement Meeting" together may have deepened the bond between Yumeko and Mary, but in this academy, friendships tend to be fragile.

In this third volume of the story about an academy filled with beautiful women, the concepts of good and evil are turned on their heads!

Hyakkaou Private Academy. An institution for the privileged with a very peculiar curriculum. You see, when you're the sons and daughters of the wealthiest of the wealthy, it's not athletic prowess or book smarts that keep you ahead. It's reading your opponent-the art of the deal. What better way to hone those skills than with a rigorous curriculum of gambling? At Hyakkaou Private Academy, the winners live like kings, and the losers are put through the wringer. But when Yumeko Jabami enrolls, she's gonna teach these kids what a high roller really looks like!

The gambling games continue...and this next game has truly lethal consequences. Will Yumeko be able to figure out its secrets in time to keep from losing her life?

Kirari has declared an open election for student council president, but it's not just the school that's on the line!

The gambling gets right underway when the young Erimi Mushibami challenges Yumeko to a game of Finger-Cutting Guillotine! In this dangerous match, the only way to win is to risk it all. Who will be brave enough-?or crazy enough-to survive to the end?!

A mysterious invitation has brought Yumeko to her second gamble of the student council presidential election: a two-on-two card game with Suzui against yet more members of the Momobami family! Sisters Miyo and Miri come from a branch of the family specializing in poisons of all types. They hold life and death in their hands-sometimes quite literally. And in this game...VERY literally! With Yumeko's life on the line, will Suzui come out on top or perish with her?!

Armed with a total of 101 votes after a one-on-one match with the vice president and a near-death gambling showdown against the Inbami sisters, Mary enters the top-three ranking for student council president. In tenth place is Yumeko, who has narrowly avoided elimination. With the president's seat still up for grabs, Yumeko joins hands with an elite Momobami member and vicious Kirari-hater hungry for the title, and that person is none other than...Terano Totobami!

Who could have predicted, though, that the transfer student would be…Yumeko Jabami?! Even after everything that transpired between them, Mary can’t shake the feeling that Yumeko never took her seriously. Now the time has come to prove herself as the two square off in the Grand Meeting,s final match! But are they really fighting only each other…?

Yumeno Yumemite has a plan to use her idol stardom to gain more votes in the student council election, but will the sudden entrance of a Hollywood Starlet put a huge dent in her plan, or push it forward?

Will this odd duo be able to keep their cool in front of a pro swindler?!
