The Black Card

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).
