Like L, she is a designer human created for scientific research and was raised by a terrorist organization. Due to her natural weakness, R's heart broke and accepted brainwashing, transforming her into a ruthless killer. For that reason, she hates and envies L for remaining a good girl no matter how much time has passed. Her charm points are her single ponytail and her breasts, which are more like her mother's than L's. "Fufu, make me feel so good A-G-L♪" [From Online Game Planet.]
