Undine

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

Employment as a Claymore
Undine appears as a bulky, muscular woman, however this is a result of shapeshifting. Her natural form is small and delicate. 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 #15 Deneve, #24 Zelda, #36 Claudia and #43 Juliana. 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 that were easily 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.
