Pocky, an upbeat high-schooler, is told she will die in three days by a psychic whose predictions always come true. Along the way, she talks about boyfriends with her two friends, meets a strange boy with heart disease, and regularly bumps into a serial bomber.

The story revolves around a hardcore Onyanko Club fanatic who decides he wants to kill the girls to prevent the young, cute idols from getting old and married - in a sense, to preserve their youth for eternity.
