フィア・キューブリック

Fear is the female protagonist of C³. She claims to be a "cursed tool" that has been exposed to so much hatred and negativity that it allowed her to gain a consciousness, and says that she came to Haruaki's home in hopes of purifying her "curse". She's actually a fictitious device called Fear In Cube, a terrible torture device from the Inquisitions. (Source: Wikipedia)
