Pursuing a string of murders involving corpses drained of blood, Kuroko and her hulking buddy, Urara, descend into the sewers to rescue Narumi from an all-too-familiar face. Narumi herself is determined to escape with her fellow captives, but between her broken leg and the mazelike underground tunnels, their odds of escape are grim. It's a race against the clock as the killer prepares for their next meal...!

Mass murderers may not have much by way of careeer skills, but Kuroko Koumori seems to have landed her dream job as a hitwoman for the Tokyo police! A license to kill other killers? That's some serious job satisfaction, right there!

Higaki, of the Sakura Pruning Group, was forged in the fires of war and fueled by a passion for revolution. Now an old man, he's engaged in a life-and-death battle with Kuroko in order to achieve his ultimate goal. But is Higaki animated by a desire to conquer Japan or by something more personal? The secrets of the Sakura Pruning Group reach far and wide-even right into Hinako's past!

The circus is in town, but it's not the only shocking spectacle around-not when hundreds of people have been tied to a floating ad balloon and there's been a knife attack among circus staff! Though seemingly unrelated, these incidents have one important link: All parties involved have a curious bout of amnesia. Signs point to an old criminal known as "Comedy Writer," but have they truly emerged from the past to strike again? Kuroko the lady-killer is on the case!

A bloody surprise turns a summer visit to the aquarium gruesome, but the details just aren't adding up. What should be a simple case of a man being eaten by a shark leads Kuroko's investigation to a small fishing town-one that's as much about the cross as it is catching hauls. A cute local girl named Suiren might just be the key to figuring it all out...though Kuroko is getting a little too distracted by her curves!

After a chemical weapon attack on the police department, Kuroko tracks down the extremist group responsible and goes on the offensive! Will she be able to bring the organization's members to justice, or will this case end up unsolved?

As a former mass murderer, Kuroko Koumori knows a thing or two about how killers think. A string of deaths points straight to an ex-con-turned-business mogul who used to skin the faces off his victims. But could it be a red herring? As chaos unfolds at the local amusement park, it might just be Kuroko's partner, Hinako, who's closest to the truth!
