An e-mail containing the words "Make a pilgrimage for the past with me", accompanied by a strangely familiar tune, lure professional hitwoman Mireille Bouquet into meeting with Kirika Yumura, a Japanese amnesiac with amazing killing skills. Could the mysteries of Kirika's lost memories shed some light on Mireille's own past?

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.

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?

Mireille and Kirika are offered a job in Taiwan- and their employer is none other than the Soldats. Despite the danger, Noir decide to accept, hoping that working for the Soldats will help them uncover some answers. But the assignment proves to be far from straightforward when they find themselves targeted by the Taiwanese assassin Shaoli, better known as the ""Cold-Blooded Killer…""

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?
