It doesn't take much effort for Claire to quickly complete her job and so Claire and Raki are off while she waits for another job. A strange man from the organization comes to give Claire a new set of clothes but not only that, he also gives Claire a "Black Card". What does this Black Card mean to Claire? Raki later has an encounter with the same man from the organization, who explains to him exactly what Claymores are (half human, half Yoma).

Rabona the Holy City that does not allow the entry of unnatural beings is being preyed upon by a Yoma and as a last resort, have to disobey their own laws and called for help. So Claire now has a job to do but it will be different from the usual Yoma hunting, it's more of a covert operation and she has to suppress her powers to do so. During her searches Claire happens to run into 2 soldiers on patrol, but they only seem to get in the way of her job. After she manages to lose them, Claire faces the Yoma which happens to be an extremely strong one known as "Voracious Eater".

Claire becomes seriously injured in her fight with the Yoma and just before the Yoma could finish them off it is interrupted and quickly escapes. Claire is then taken back to the inn to recover from her serious injuries and Raki waits by her bedside hoping that she'll eventually wake up. Father Vincent decides to cooperate with Claire to help her find the Yoma but something doesn't seem right. Defeating the Yoma is the least of Claire's worries as she begins to lose control.

Another Claymore known as Teresa has appeared in a town where she quickly dispatches a Yoma, with no effort. She is well-known as for her nickname "Teresa of the Faint Smile" because she never releases her Yoma powers. In the town of Teo, as soon as she arrives there she ruthlessly attacks any Yoma she senses and after the massacre a girl with no name who was with one of the Yoma seems to be very attached to Teresa. This girl ends up following Teresa no matter what she did.

After naming the girl who was following her, Claire; Teresa is heading towards the town of Rokut to drop her off. At night while they are resting in the woods, the man whose arm was chopped off is back for revenge. It turns out that the girl was able to save her and not from the man but to save her lonely heart. Teresa later encounters the bandits but this time they have done something unforgivable which forces Teresa to do something unforgivable.

Two more Claymores have appeared, Sophia and Noel who have entered a town that has become a Yoma hive, don't require much effort to eradicate the hordes of Yoma. There are still some Yoma left but that is until Irene nicknamed, "Flash Sword Irene" finishes them off. Following Teresa's betrayal, the number 2-5 Claymores have gathered with orders to execute Teresa, but who is the remaining Claymore yet to arrive? The ultimate battle between Claymores is about to begin.

Continuing where the battle left off, Teresa of the Faint Smile will now have to face the Numbers 2-5 Claymores, who have released their full power. Knowing that she has never need to release her power, how will Teresa fair against these tough opponents? Overcome by her emotions, Priscilla surpasses the limit and becomes what is known by an "Awakened One".

Three Claymores arrive in the town of Toriro to only find Claire, who has already taken care of the Yomas. It is revealed that what Claire defeated in the Holy City was not a Voracious Eater but a regular Yoma; because Voracious Eater is a public term for what the organization labels an "Awakened One". Claire has been added to the expedition team to hunt an Awakened One, as a chance to measure the limits of her skills. How will Claire ranked no. 47, fair against such a powerful being after a shocking turn of events?

The team of Claymore reach the mountains and are surprised by what they encounter, a Male Awakened One. Another Claymore and a handler are watching the battle from a distance, but what do they appear to be plotting? The battle reaches its climatic stage, with all but the "Phantom Miria", badly wounded. This may be what the Awakened meant by "true despair", however Claire is one to know what true despair is really like and this is not it.
