Kyoko is the daughter off Papa C. She is shy, big breasted and older, just the way Tomonori likes them, fortunately for him, she has a huge crush on him.

Kyoko has a split personality that is held back by wearing glasses. If she ever takes off her glasses, her other (dominant) personality will come out and oddly enough, she is very strong and extremely aggressive.

Eventually, Kyoko will be in love with another person named Ryuonoske and no longer chases after Tomonori.
