The Seven Deadly Sins: Signs of holy war 4-Episode Special Premieres on August 28

This year's 24th issue of Kodansha's Weekly Shōnen Magazine is revealing on Wednesday that the Nanatsu no Taizai: Seisen no Shirushi (The Seven Deadly Sins: Signs of holy war) television anime special will premiere on August 28. The four-week special will air on MBS and TBS on Sundays at 5:00 p.m.

The announcement confirms that the Arslan Senki: Fūjin Ranbu (The Heroic Legend of Arslan: Dust Storm Dance) television anime series, which will premiere on July 3 in the same time slot, will air in full before The Seven Deadly Sins: Signs of holy war premieres.

The anime's staff had announced in October that production on a new television anime series was green-lit for this year. The original announcement of the new television anime series had stated that the new series would feature the same staff, but the official website lists a different staff for the special. The staff has not specified if the announcement last October was for this four-week special.

Original manga author Nakaba Suzuki is writing a brand new story for the special.

The first television anime of the manga premiered in Japan in October 2014, and ended with 24 episodes. The manga also bundled two original video anime projects last summer.​
