The film will take place half a year after the story of the original television anime series.
The original Kabaneri of the Iron Fortress television anime aired from April-July 2016.
The YouTube channel for Fuji TV’s Noitamina programming block began streaming a second promotional video on Friday for the Kabaneri of the Iron Fortress: The Battle of Unato (Kōtetsujō no Kabaneri: Unato Kessen) sequel anime film.
The anime will also stream on Netflix and Amazon Prime Video simultaneously with the theatrical release.
