Like Burn Up W and Burn Up Excess, the series centers on a busty police officer and martial artist name Rio Kinezono, who just wants to find love in her life... so much so that she often changes around her living arrangements just to attract the right man. So far, the only man she was able to attract is her perverted superior, Yuji Naruo... and he's being protected by Matsuri Tamagawa, his overly-zealous girlfriend.
