The Armored Division Police are busy decrypting the mysterious disc found after another encounter with the mysterious Knight Sabers. Nene of the Sabers works for the AD Police -- and is there when a mysterious mech arrives to take the disk back, by force! It's up to Priss to take on the intruder as well as rescue her friend, but can she handle a creature that thinks nothing of breaking into the most heavily armored HQ in all of MegaTokyo? It may be a company town for Genom corporation, but a few rise up to challenge the out-of-control robot "Boomers" that plague this future world. When the Armored Police Division (ADP) impounds the encrypted hard disc the Boomer was carrying, a number of new forces take interest.
