It seems like a simple job for Noir when they are hired by a widow to take revenge on her husband's killer. But when the job turns out to be a set-up, the tables are turned, and the hunters become the hunted. Can Kirika and Mireille hope to out-think their enemies and escape with their lives?

Mr Hammond is a man of many roles- on the one hand, he is president of the nefarious Atride Corporation, well known for inciting wars to make a profit, but on the other, he is a father adored by his teenage daughter Rosalie. And now, in sunny Ulgia, Hammond has another role- as Noir's next target. Yet there are still enemies in the shadows who want nothing more than for Noir to fail.

In exchange for a document that has a connection with the mysterious Soldats, Mireille and Kirika assassinate a Mafia Don. But the Mafia is well known for its revenge policies, and Noir soon find themselves the target of the ruthless Mafia princess known as the Intoccabile, a woman who Mireille has met long ago, and has cause to fear.

Noir and the Intoccabile still have unfinished business with each other after their last face off, and each side knows that matters can only be resolved with a final showdown. To that end, both sides travel to Sicily, where Mireille and the Intoccabile met as children. But with Kirika's arm injured and Mireille fearful and doubtful about her ability to defeat the Intoccabile, does Noir have any hope of victory? And will Mireille and the Intoccabile's past play a part in the coming encounter?

Kirika and Mireille are in for a surprise when they find that another professional has already taken out their next target. Word on the streets is that Noir was the killer- do the rumours refer Kirika and Mireille, or is someone else using the same code name?

Ten years ago, Mireille left Corsica with her uncle Claude, who looked after her and trained her as an assassin. Now, Claude has returned to Paris, but Mireille's delight at seeing her uncle again is tinged with doubt. An assassin of Claude's calibre is bound to have secrets of his own- secrets that could spell trouble for Noir…

Kirika and Mireille's mission to destroy the Hang Yiban triad went awry when the Hang Yiban sent their own assassin- the ruthless Shaoli, to destroy Noir. Now, Mireille has been captured by the Hang Yiban, and Kirika must work with the mysterious Chloe to free her. But even if Mireille can be rescued, Noir still has the job of eliminating both the Hang Yiban leaders, and Shaoli herself…

Mireille and Kirika continue to chase leads that might help them locate a copy of the manuscript about the Soldats, unaware that the danger is greater than ever. For the Soldats council is fed up with playing Altena's games in which Kirika and Mireille are given ‘trials', and decide that now is the time to finish them off, once and for all…
