Katea was a female Claymore, and the number 32 of Clare's generation. She was asigned to the Mount Zakol Hunt, leaded by number 9 Jean, where she was eventually ambushed, along with the rest of the team, by Abyssal One Riful of the West, and her partner, former number 3 Dauf. After a long session of torture, Katea finally Awakened. However, after being defined by Dauf as weak, Riful orders her death, as she wasn't useful for her army. Katea appeared to have been strong-willed, having resisted extensive torture from Riful and Dauf even when one of her comrades had already died in front of her.

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.
