After what occurred in the mountains of Zakol, Jeane is accompanying Claire until she can return her favour, however Claire already feels thankful to her because she is now able to fully control her "Flash Sword". Out of the blue Claire's handler Rubel turns up with the no. 5 "Rafaela" but not with request for her return to the organization but with orders to join the war, against Awakened beings, in the Northern Lands. This mission brings upon an unexpected reunion.

Awakened Beings have launched a surprise attack on the city of Pieta, forcing the teams of Claymores to begin their battles against these unbeatable creatures. Even with these incredibly powerful Awakened Beings to fight against there may be some Claymores who are able to handle this sort of situation, which will only get tougher in the future.

In the Northern country Raki is with two surprisingly helpful people however he is unaware that these two are the two most powerful Awakened Ones in the area; "Priscilla" and "Person of the Abyss, Isley". Meanwhile after having just survived the first attack, the teams of Claymores are recovering and replenishing their supplies along with some interesting developments.

Having just heard the news of what happened in the City of Pieta, Isley has ordered his entire army of 27 Awakened beings to annihilate the Claymores located there. With the probability of this mission ending in success zero, no matter the odds the teams of Claymores are still determined to carve out their path of survival. Meanwhile Raki is heading towards Pieta with Isley and Priscilla when he later discovers something shocking.
