"Doot-do-do, doot-do-do, doot-do-do, hey!" Clara is one of the stranger students at the school, acting very much like an excited child. She has abundant energy that most students can't keep up with. Other students find her weird and hard to deal with, but are drawn to her because her inherited power is so convenient. Since she had no friends, she would give students snacks and drinks as "payment" for playing with her. Her immature nature makes it difficult for others to get along with her, so much that most of the class can't stand her and wonder how Alice and Iruma can tolerate her so much. Despite her childishness, Clara is fully aware of how people view her as an annoyance yet still gives in to their demands in an effort to fit in. After befriending Iruma and Alice she learned to stop letting students use her for snacks and embrace herself and learn to befriend others in her class. She is very grateful to Iruma and Alice as they are the only ones who play with her unconditionally and is deeply attached to them. Because of this, she easily gets angry when they can't play with her. After Azazel Ameri starts hanging out with Iruma, Clara became deeply jealous of them spending time to the point she resorted to using various ideas to interrupt their time together. However, her jealousy was moreover them "playing" with them instead of her, and was more interested in playing with Iruma. She was more than willing to fight Alice to get to him or using her powers to break down the door in Ameri's room. Because of her childish nature, she is so innocent that she is 2% erotic (with babies being 3% erotic), with all her attempts at "enchanting" Iruma from a book ending in constant failure. Despite this, Clara will not force him to fall for her, as she refuses Professor Raim's love potion to force him on her. Although she seems to mature somewhat as she declares her honest intentions to "enchant" him, she rises to 10% (which actually makes Iruma skip a beat). But she wasn't alone in her being a simple-minded demon. The Valac Family had the same personality, except for the father and Uralaka. "Because I'm his super-greatest BFF!"
