The series is a tongue-in-cheek look at a special operations unit in the Tokyo police force called "Team Warrior", with large amounts of fan service thrown in for good measure, exemplified by the inclusion of ADV's trademarked "Jiggle Counter" on the DVDs along with Plastic Little.

In the field, Rio is usually flanked by Maya Jingu, the green-haired team sniper who appears to have a serious lust for ranged weapons (specifically assault rifles).

Lilica Ebett, the sprightly pink-haired girl who's a computer expert, can pretty much crack into any information system, and Yuji Naruo, a perverted, camera-toting voyeur, always serves as Warrior's drop-operation pilot and driver.

Maki Kawasaki, the mysterious, bespectacled superintendent, is charged with commanding Warrior in the field and administering their various missions as they arise.

The series chronicles the team members' adventures as they slowly track down a sinister city plot involving the manufacture and distribution of military armaments.
