The master of this emotion is terrified by her own doppel, which swings around its blade without hesitation and cuts up everything, even her treasured books. However, it's also true that, while not wanting to admit it, deep down she feels free.
Unlike its master who shows doubt at every little thing, this doppel acts without a thought, severing not only the flesh of her targets, but all magical bonds as well.
Physically, being able to attack only at close-range, it often ends up attacking her allies who happen to be nearby, making itself vulnerable. Yet though she may wish to prevent friendly fire, this doppel's 'master' of this emotion cannot control it at all, and is left paralyzed in fear as it rampages.
