This year's 20th issue of Kodansha's Weekly Shōnen Magazine announced that Nakaba Suzuki's The Seven Deadly Sins (Nanatsu no Taizai) manga is being adapted into a TV Anime. During the combined 36th/37th issue of the same magazine the cast and staff for the upcoming anime was revealed. The cast includes: Yuuki Kaji (Attack on Titan), Sora Amamiya (Tokyo Ghoul), and Misaki Kuno (Oreimo). The anime will be created by A-1 Pictures (Fairy Tail, Magi, Sword Art Online) and will be directed by Tensai Okamura (Darker than Black, Blue Exorcist), will be written by Shōtarō Suga (Lagrange: The Flower of Rin-ne), with Keigo Sasaki (Blue Exorcist) providing character designs and Hiroyuki Sawano composing the music.
Kodansha Comics, the publisher of the manga in North America, describes how the story begins:
When they were accused of trying to overthrow the monarchy, the feared warriors the Seven Deadly Sins were sent into exile. Princess Elizabeth discovers the truth - the Sins were framed by the king's guard, the Holy Knights - too late to prevent them from assassinating her father and seizing the throne!
Now the princess is on the run, seeking the Sins to help her reclaim the kingdom. But the first Sin she meets, Meliodas, is a little innkeeper with a talking pig. He doesn't even have a real sword! Have the legends of the Sins' strength been exaggerated?
The manga already has a crossover chapter with Fairy Tail, another Weekly Shōnen Magazine fantasy adventure manga that inspired an anime. Nakaba Suzuki launched the manga in Weekly Shōnen Magazine in 2012, and Kodansha Comics published the third English volume this month. Crunchyroll is posting the new chapters as they appear in Japan.
