Roberta is a witch from Puella Magi Madoka Magica.
Bio
The birdcage witch. Her nature is rage. She continuously stamps her feet inside her cage, directing her rage at those who do not respond to her. This witch is extremely fond of alcohol, and her minions are also easy to burn.
Minions
Gotz
The birdcage witch's minion. His duty is to act with frivolous indiscretion. These birds that swarm together are idiotic men. Even though they are total good-for-nothings, they try to attract her attention by swarming around her feet and attempting to woo her. They are nothing more than objects of disgust to the witch.
