Chizuko's Younger Sister

The film centers on Mika Kitao (北尾 実加 ''Kitao Mika''; Hikari Ishida), the clumsy and slow younger sister of Chizuko Kitao (北尾 千津子 ''Kitao Chizuko''; Tomoko Nakajima), shortly after Chizuko dies in a freak accident. Although the sisters were very close, it is apparent that Mika lived in the shadow of her older sister's accomplishments. One night, Mika is almost raped by a stranger while walking alone outside. However, during the attack, a person resembling Chizuko silently gestures towards a rock on the ground, which Mika uses to hit her assailant and get away safely.
