The story begins when high school student Kazuki Muto is killed one night saving a mysterious girl from a monster, only to wake up in his school dorm, believing it to have been a dream; however, he soon finds out that dream wasn't a dream at all when a giant serpentine monster attacks him and his sister. Tokiko Tsumura, the girl he saved, explains that the monster is a homunculus. Kazuki had been attacked and killed by it when he was rescuing her; however, she, feeling responsible for him, revived him by placing a Kakugane medallion in his chest, serving as a replacement heart. The Kakugane, as Tokiko explains, is an alchemical device that, when activated, takes a certain form based on the Kakugane's user, forming a unique Buso Renkin. The Buso Renkin is the only thing that can destroy a homunculus monster. Using this, Kazuki creates his own Buso Renkin (the Sunlight Heart, a huge lance). Along with Tokiko and her own Buso Renkin (the Valkyrie Skirt, an execution scythe), Kazuki joins the fight against the homunculi and their master.

Follows the exploits of Team Warrior, a special anti-terror wing of the Neo-Tokyo Police force. Team Warrior is comprised of the habitually broke Rio, gun-crazy Maya, computer specialist Lillica, tech-expert Nanvel, piliot/voyeur Yuji, and is led by the enigmatic Maki. The team faces a number of missions, ranging from bodyguard duty, breaking up robbery and arms rackets, and providing security for a very powerful tank. Rio and company continually thwart the terrorist aims of Ruby, an operative for a shadowy cabal of powerful men. Before the final showdown, the circumstances behind the formation of Team Warrior, how the precocious Rio came to join it, and Maki's painful past will be revealed. (Source: ANN)

To the unsuspecting eye Maki, Reimi and Yuka may not look like ace crime fighters, which might explain why they're stuck on traffic patrol instead of more exciting police duties. All that changes when Yuka gets herself kidnapped by a white slave organization run by a politically connected businessman who's got the rest of the police cowed. Now it's up to Maki and Reimi to don skin-tight battle armor, liberate a tank, and make sure that a certain slaver learns that when you play with fire, you're going to get your ass burned!
