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.

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.

Still upset over the truths she learned in Corsica, Mireille wants nothing more than to be alone, and sends Kirika away for a while. Wandering the streets on her own, Kirika is approached by a faction of the Soldats, promising to supply information. But if Kirika follows this lead, she will be leaving Mireille alone- and vulnerable…

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…
