Haruka is a girl who dreams of being a mangaka, but is unable to lead a normal school life due to a brain tumor she suffered from in elementary school, transfers to a correspondence high school. On her first day, she has a fateful encounter with a handsome boy named Takumi, who shares the same name as the main character in a manga she is writing, just like in a manga. Takumi quickly enters the shy Haruka's mind and talks about his dreams. Haruka finds herself becoming more and more attracted to him. This is her first time in love. However, just as she seems to be at the peak of happiness, Haruka's brain tumor recurs. Despite her despair, Haruka does not curse her fate, but chooses to “live” even at the risk of being left disabled.

A fantasy that anthropomorphizes the stray cats living on Kitagijima, a remote island off the coast of Okayama, much like Yumiko Oshima’s classic manga "Wata no Kunihoshi". The film depicts young girls conversing in “cat language” (with subtitles), occasionally interacting with humans, as they live freely and spontaneously yet still struggle desperately to survive.
