The official website for the television anime adaptation of Mado Nozaki's Babylon novels revealed on Friday that the series will premiere on Tokyo MX on October 7 at 10:00 p.m. The series will then debut on BS11 and AT-X later that night.
The series' first chapter "Itteki no Doku" (One Drop of Poison), which includes episodes 1 to 3, will begin streaming in advance on Amazon Prime Video in Japan on October 6 late at night at 12:00 a.m. (effectively October 7). The anime will stream exclusively both inside and outside Japan on Amazon Prime Video.
Revoroot is producing the anime, and Twin Engine is also credited for production.
The suspense story centers around Zen Seizaki, a prosecutor with the Tokyo District Public Prosecutors' Office. While investigating illegal acts by a certain pharmaceutical company, Seizaki stumbles across a conspiracy over an election for an autonomous "new zone" established in western Tokyo.
Kodansha's novel label Kodansha Taiga released the novels' first volume in 2015, followed by the second in 2016. The third and final volume shipped in November 2017. Nobuhide Takishita launched a manga adaptation of the novels in February, and it will end with two volumes that will both ship on October 9.
