Kokkuri (1997)

Original title: こっくりさん

Schoolgirls on the verge of adulthood know that boys can be feckless and girls treacherous. Three friends gather around a Ouija board to call forth the spirit of Kokkuri.

She also has a secret life as the voice of a midnight talk show host, the sexually-charged Midori. Mio must explore her past and her new feelings. Can she hold off the power and predictions of Kokkuri to enter adulthood, or will the destructive and romantic side of teen spirit be too powerful?
