Yuuma's classmate whose parents own a company that creates sex toys of all kinds. Charlotte's father is Japanese and her mother is German. It is quite unsuprizing their daughter would follow their steps in the same field, becoming an inventor of sex toys, among other things. At such a young age she was able to create a robot butler to act as her servant and protector. Charlotte is very confident in her inventions and believes all sex toys are works of art. Strangely enough she is obsessed with Watanuki Yuuma's genitalia and regards them as "the best genitals ever", going as far as wanting to produce vibrators shaped like them.
