The official Twitter account of Hobby Japan’s Seven Mortal Sins anime has announced that the series’ fifth episode will not air as scheduled on May 12, 2017. The “Episode 4.5” compilation episode, titled “Exactly a Demon’s Deed…,” will air instead of the fifth episode. The anime’s staff plans to air the fifth episode “next time.”
The series is described as:
Because she committed the sin of pride against God, the Great Angel Lucifer was cast into Hell and became a Fallen Angel. Also at the lowest level of Hell, the hierarchy of demons have sealed away Lucifer’s powers. Lucifer had lost everything, but along with the Demon King of Envy, Leviathan, that admires Lucifer and a high school girl she met on Earth named Totsuka Maria, she becomes the Demon King of Pride Lucifer and begins her journey to revenge on the Seven Demon Kings of Hell. A book of Revelations with the “Seven Deadly Sins” portrayed by beautiful Demon Kings is about to begin.
Seven Mortal Sins premiered on Japanese television on April 14, 2017. Crunchyroll is simulcasting the anime as it airs in Japan.
