Ladies and gentlemen, it has been an epic run, but Meliodas and the rest of the Seven Deadly Sins (plus Elizabeth and Hawk) are about to say goodbye. According to the 23rd issue of Weekly Shonen Magazine, the manga will be reaching its climax in the next chapter. It will be released inside the magzine’s 24th issue, due out on 15th May.
The next chapter is the manga’s 310th chapter, and it’s fittingly titled “Sayonara Nanatsu no Taizai”. This has been a long time coming, as Suzuki hinted in an interview last that The Seven Deadly Sins manga will be ending soon.
In addition, the anime will be returning with a new studio. The title for the new anime is The Seven Deadly Sins: Wrath of the Gods. Studio DEEN will be animating, and it will be heading towards the series’ climax. It will premiere sometime in autumn 2019.
