Having gone into business as Noir, Mireille and Kirika take on their first job together- the assassination of a far right terrorist and his collaborator in the Peace Department.

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?

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.

When Kirika begins spending all her time down at the river in the company of a young painter, Mireille warns her not to get too close- after all, relationships aren't something you can pursue easily when you're in their line of work. Mireille has problems of her own, however- an old job comes back to haunt her when one of the survivors decides to put together his own mission of revenge.

It has been a decade since Mireile was forced to flee from Corsica after the murder of her family, and she has always been too afraid to return- until now. Determined to uncover the truth about her parents' murder and its connection to the Soldats, Mireille returns to her childhood home. But as she tries to stir up information from the past, she attracts the attention of those who would rather it remained buried…

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.

Only two maidens can serve as Noir, but now that Mireille has arrived at the manor, all three candidates are present- and one must lose out. Will Chloe and Kirika pull together to remove the ‘outsider' from contention, or will Mireille find a way to get through to her former partner? Only a heated conflict in the manr grounds themselves can decide the answer…
