It fits on her hobby which is like to doing experiments with chemicals. Kyokooves to doing chemical experiment until she feels so tired. After tired, she will sleep until morning. Kyoko considering her chemical experiment is not only a hobby, but it was a part of her life. Personally, Kyoko is a loner/introvert girl. She doesn't like to stay at crowd for too long time. Kyoko doesn't like to be at crowd doesn't mean she is anti social. Kyoko still enjoy talking with her family or her closest friend because her family and her closest friend is understand her personality. And Kyoko even enjoy talking with you as her boyfriend. Kyoko see you as her joking material. To her younger brother and you, Kyoko is a teasing girl. Kyoko is originally from Fukuoka and spend her school times there, but studied at Tokyo.)
