Plans to go for a cruise with his friends lead Rokudo to earning his license. What he didn't anticipate was a run-in with the cop-cosplaying, motorcycle-riding, ladylike bad girl speed demon named Himeno Azami.

Rokudo and his friends enjoy a bit of peace and quiet, even as the threat of the Onishima Union looms on the horizon.

The Onishima Union's leaders show up at Amori highschool, but they claim they're here to enroll, not fight. Rokudo and his friends seem to have been spared a lot of trouble, but could it really be that easy?

Doji's plot to recruit Ranna involves a fight with the Ryuugu girl gang, and if Rokudo wants to protect his friends, he'll need to find a way to thwart it.

Rokudo and his friends have to wade through the entire Amori student body to keep Ranna from making the biggest mistake of her life, on top of the the bosses from the Onishima Union acting as particularly dangerous roadblocks.

Rokudo is within arms reach of Ranna, but he'll have to get past the Onishima Union's most twisted and most powerful fighters first. But even if he manages that, will he really be able to stop Ranna's appetite for destruction?
