Riful

Riful almost always appeared whimsical and child-like, often acting polite and cheerful even when threatening someone with a torturous death. She also expresses hints of sadism in the torture of Claymores, but for the purpose of making friends or mustering aid against enemies. From time to time, however, Riful would also exhibit anger, especially when she was fooled by Renee. When faced with imminent death, she even shed tears. (From Claymore Wikia)
