Kazuya Konaka spins this teenaged coming-of-age drama\mind-bending sci-fi fantasy. While trying to blend in with her high school classmates, Midori (Chiharu Niiyama) -- a passionately romantic lass -- can't stand her fellow student's petty politics. Yet she also harbors a major crush on the hunky, smoldering Yamazawa (Masaaki Takari), who doesn't seem to realize that she exists. One day at the apartment complex where she lives, Midori meets Mayumi (Yasue Sato), a young woman with remarkable self-possession and freakishly piercing eyes. The next day, Mayumi is introduced as a transfer student. When her homeroom teacher asks her what her future aspirations are, she says calmly, "it would be nice if this world isn't destroyed." She then raises more eyebrows when she explains in great detail elements of Heisenberg's uncertainty principle to her baffled physics teacher. Midori finds herself drawn to this new girl and Mayumi feels likewise. Soon, Mayumi reveals her dark secret: she and her mother leapt to this dimension just before her home planet went up in a nuclear explosion. She then tells her flummoxed new friend that inter-dimensional travel is really quite easy. Soon Midori is leaping from world to world, landing in not so much in new realms but new lives. She finds herself a foot soldier in a rebel movement, and an inmate in an insane asylum, among others. Later, Midori learns the truth about her friend Mayumi, Yamazawa, and her own existence.
