Undine

Undine was Claymore #11 during Clare's time and was a notably brash and aggressive Claymore. She is the only Claymore to carry two swords, earning her the title Undine of the Twin Swords.

Appearance
Undine has long, pale hair which she tucks behind her ears. She wears the standard Claymore uniform. Undine appears as a bulky, muscular woman, however this is a result of shapeshifting. Her natural form is small and delicate.

Employment as a Claymore
Deneve deduced that as a young Claymore, a friend died protecting her and out of shame she developed the attitude and build she later possesses. The other sword that she carries is the sword of that fallen Claymore. Because of this event she often bullies weaker Claymores, telling them to stay out of her way and out of the battle. However, this is only because she cares for them and worries about their safety.

The Northern Campaign
Undine was selected as one of the 24 Claymores to take part in the Northern Campaign. She was made one of the five captains because of her high ranking, leading Deneve (#15), Zelda (#24), Claudia (#36) and Juliana (#43). She battled the Yoki manipulating Awakened Being, which tried to force her to decapitate herself. She used her brute strength to move her two swords, meaning she only sliced her cheeks. It then tried to pin her down, but again she used her muscles to stand back up. She attacked again, but didn't notice the Awakened Being was manipulating her Yoki and she had almost passed her limit. Deneve hits her out the way just in time, preventing her from Awakening. When Deneve failed to decapitate the Awakened Being Undine placed her swords over Deneve's, using her strength to push Deneve's swords through its neck, killing it.

She openly criticised Miria's plan during the first battle, believing that it put the weaker Claymores in danger. She was proved wrong though, as there were no casulties during the first battle. She was later confronted by Deneve, who she then told about her past. Undine was one of the four captains killed by Rigardo during the second battle. Deneve used Undine's "borrowed" sword as her gravestone, taking Undine's own sword with her in memory of her captain and comrade.

In the anime, Rigardo commended Undine on her strength when she blocked his first attack. In the manga, she was killed before she could do so.

Personality
Undine is notably brash and agressive and many of her fellow Claymores appear to fear or dislike her. She is particularly tough on low ranked Claymores but it revealed that this is merely through her desire to protect those weaker than herself. She appears to be a loyal friend as she constantly carries her deceased friends Claymore.
