Carol is an airhead like her mother. Eccentric, almost permanently cheerful and totally oblivious to how modern society works, she was under the assumption that everyone's household was like hers. She also seems to enjoy teasing and pushing her boundaries with everyone. She often makes blunt remarks very casually, even to complete strangers. Despite being physically weak, she seemingly does not fear anyone, including delinquents and Gorou Aizawa (Tomo Aizawa's intimidating father).
