Irene

Claymore number three (before Priscilla number two) of the 77th generation, she is known as "Quick Sword Irene", capable of lashing out innumerable lightning fast sword strikes by accumulating all her Youki energy in her sword arm. Even thought she was considered dead by the Organization, she merely lost an arm from the encounter with the Awakaned Priscilla. She saves Clare from Ophelia and teaches her the Quick Sword technique. Irene gives Clare her right arm, so she can control her technique better. After Clare leaves her shelter, Rafaela appears and kills Irene.
