She has always wanted to have friends and close companions, but within her family, she has felt ostracized because of her parentage and has not even had the courage to get to know Hakuei or Hakuryuu, the more approachable of her relatives. Instead, she occupied herself with becoming skilled at kemari by herself, playing make-believe by herself, doing a fashion show by herself, etc.

History
Kougyoku is Second Emperor's youngest child. She has a history like Alibaba: she wasn't born into royalty like her siblings, because she is the daughter of an unknown, lowly courtesan. She calls herself as a "lowborn".
