Undine is Claymore No. 11 of Clare's generation. She originated the technique of using two swords, earning her the nickname "Undine of the Twin Swords" (双剣のウンディーネ, "Sōken no Undīne"). Deneve later pickes up Undine's sword after her death and adopts her practice. Undine was notably brash and aggressive. She was particularly harsh towards weaker Claymores. She considers them to be nothing more than impediments to her mission, but later it is revealed that she only wanted to protect those weaker than herself. She appeared to be a loyal friend as she carried her deceased friend's sword in her dominant hand and held onto it with great care. Even after getting kicked by Deneve, she refused to let go of it. Despite her tough attitude, she has the extreme fear of pushing herself too far and awakening.
Claymore
When a shapeshifting demon with a thirst for human flesh, known as "youma," arrives in Raki's village, a lone woman with silver eyes walks into town with only a sword upon her back. She is a "Claymore," a being manufactured as half-human and half-youma, for the express purpose of exterminating these monsters. After Raki's family is killed, the Claymore saves his life, but he is subsequently banished from his home. With nowhere else to go, Raki finds the Claymore, known as Clare, and decides to follow her on her journeys. As the pair travel from town to town, defeating youma along the way, more about Clare's organization and her fellow warriors comes to light. With every town cleansed and every demon destroyed, they come closer to the youma on which Clare has sought vengeance ever since she chose to become a Claymore.
