Riful

Riful (possibly intended to mean Riffle, corresponding to her Awakened form) was the Claymore #1 of the first generation of female Claymores. She was the youngest Claymore to Awaken. She is the Abyssal one of the West. She lives in the Western territory, together with her lover Dauf.

Appearance
In her human form, Riful appears as a whimsical and cheerful young girl with long brown hair, but in reality is completely amoral, with a complete disregard for any who come between her and her goals.

In her Awakened form, Riful retains a feminine humanoid form, but one composed of fleshy strips. Her lower body is an immense mass of such strips, which are incredibly resilient and capable of lashing out at high speeds to ensnare or impale her opponents. The humanoid portion of Riful's form is a deception, as her enemies will tend to attack that area in the assumption that her vital organs are located there. In actuality, that portion contains no vital areas whatsoever.

First Encounter With Clare
Riful first encounters Clare when she comes to rescue Jean. Riful wanted to create a powerful army full of Awakened Beings and was torturing Claymores in order to make them Awaken, which is why she had imprisoned Jean. Riful decided to let Clare fight with Dauf while she sat and watched from the side. Galatea then got involved, giving Clare time to save Jean. Dauf was overwhelmed by the three Claymores, causing Riful to end the fight. She decided she wanted to 'recruit' the three to her army, but left them time in order to get stronger before turning them into her Awakened allies. Riful also suggested that the only way to beat Isley was for the three to join her.

She later appeared before Isley after Luciela's defeat, warning him to not expand into her territory. It was then she realised that there was something amiss regarding the story of Isley defeating Priscilla. She noted that Priscilla was much stronger than either Isley or herself. This was one of the few times where she showed real anger.

After Seven Years
Riful has now changed her focus to acquiring of Claymores skilled at sensing and manipulating Yoki. She attempted to recruit Audrey and Rachel, but Clare, Miria, Helen and Deneve intervene. She seemed pleased to see Clare was still alive and even asked how Jean and Galatea were. She seems slightly upset to hear of the death of Jean.

She later runs into Renee and captures her. She takes her to her base and has Dauf tear off some of her limbs. Riful tells her she will let her re-attach her limbs and let her go if she cooperates. She then shows Renee the merged bodies of Rafaela and Luciela and tells Renee all she wants is for her to use her Yoki manipulation to make them awaken. Renee asks Riful what she will do if the creature is stronger than her, to which Riful cheerily replies she will just kill it.
