According to October issue of Animedia magazine, the airing of Shiki on Fuji TV will be interrupted for 3 weeks after the airing of episode 12 on September 16. Episode 13 is scheduled to October 14. However, this interruption will occur only on Fuji TV so other TV stations will soon catch up with Fuji TV, which was the first one to air the new episodes. Kansai TV is airing episode 12 on September 28, and Toukai TV on September 30.
