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 partnership has come to an end, and with no place to return to, Kirika finds herself wandering through the wilderness. Found and rescued, she is taken to what seems like a simple country village. Yet when Kirika realises that all the villagers not only recognise her, but have been expecting her arrival, it becomes clear that all is not as it seems.

Mireille and Kirika have overcome everything that the Soldats have thrown at them, and proven themselves truly worthy of the name Noir. But there is one last piece of business they must take care of at the manor- a final face off with Altena, the woman who has been manipulating their lives from the very beginning. But will this showdown set them free, or is it just the last move in Altena's game?
