The organizations first attempt at making a controlled awakened claymore. But she was too powerful and escaped. She then became known as the third Abyssal One and rules the south.
Luciela was Rafaela's older sister and the Abyssal One of the South. She was originally the top-ranked Claymore in Class 76, but she became an Awakened One after a failed attempt at a "soul link" experiment conducted by the organization, which also wounded her sister Rafaela. Her awakening was disastrous and drove the Organization to the brink of ruin, as it took place in the Organization's headquarters. This experiment was an attempt to create a controlled awaken one by having Luciela align her spirit with Rafaela (Alicia and Beth are a successful product of this technique). It was said that the project only worked with identical twins, which Luciela and Rafaela were not. Most recently Luciela duelled with Abyssal One Isley following his incursion into her territory. Ultimately she was defeated, retreating after nearly exhausting her Yoki. She was so injured after the battle that she had to revert back to her human form, and was later found by Rafaela. Wanting to finish off Isley, she tried to make Rafaela join her. Rafaela didn't realize this till after her sister embraced her, and pleaded for her to Awaken and align with her. But Rafaela broke her weakened sister's back, while Luciela killed her as well. In Chapter 82, it has been revealed that she and Rafaela are still alive, however she is physically and partially merged with her sister. Both her and Rafaela are under a vegetative state since the 7 year span. Currently Riful has possession of them, and intends to awaken them both to further her plans.
