Time is running out for the five boys of Hachimitsu Private Academy! With their expulsion looming, it's time to stake life and limb on making a prison break and baring the Shadow Student Council's misdeeds! And having challenged the vice president to an arm wrestling match, they might actually lose those limbs...

On the outskirts of Tokyo stands Hachimitsu Private Academy, anall-girls boarding school for elite young women.

With their expulsion looming, it's time to stake life and limb on making a prison break and baring the Shadow Student Council's misdeeds! And having challenged the vice president to an arm wrestling match, they might actually lose those limbs...

The day of the cornered male prisoners' expulsion comes and goes, and the tale takes a new turn as the roiling fates of both the boys and the girls play out! Kiyoshi and company finally break out of prison and are hard at work enjoying their peaceful school lives...but a storm is brewing, and Mari, Meiko, and Hana of the Shadow Student Council find themselves behind bars!

While they may be enemies, Kiyoshi and Mari need to work together like their lives depend on it--because they do! With snake venom coursing through Mari's body, the only way to save her is for Kiyoshi to get his lips between her thighs.

Chiyo thinks there's something going on between Kiyoshi and Mari, and her response to Kiyoshi is rather bold! "You can feel them, if you'd like." Get a handful, or don't? Start with the left one, or the right one? In the hell that is the Prison, is this a brief visit to paradise?
