Toxic Daughter: Chi-chan manga is an intriguing prologue to director Eisuke Naito's horror film Toxic Daughter and features story and art by Shuzo Oshimi, the author of Flowers of Evil and Blood on the Tracks.

It's been years since Chi, a mysterious outcast and borderline dropout, and her childhood friend Yua last spoke. One day, Chi shows up to school with a handful of dead bugs and starts a commotion that gives Yua's classmate, golden boy Kodai, an idea: he's going to bring Chi back into the fold, and he needs Yua's help to do it. But good intentions can lead to bad places, and the darkness in Chi may be more dangerous than they ever imagined.
