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!

Kuroko has challenged the culprit behind the master swordsmen murders-which means her life is on a razor's edge! Uncharacteristically overwhelmed by her opponent, Kuroko must rely on deceit as she faces a blade wielded with superhuman senses. Reinforcements are on the way, but can she guarantee everyone's safety against the insatiable blood lust of a vengeful soul...?

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!

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!

A mysterious killer has left a trail of dead swordsmen in their wake, and the grisly corpses hint at a fiend possessed. A chance to confront the culprit presents itself, but Kuroko finds herself in unfamiliar territory-when, for the first time, an opponent completely outclasses her in combat! In order to win (or even survive) against this unparalleled swordsman, Kuroko's going to need an ace up her sleeve, and her answer is...movie magic?!

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!

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!
