The Seven Deadly Sins also known as Nanatsu no Taizai is an anime based off of the manga books written and drawn by Nakaba Suzuki. Manga basically is the Japanese version of comic books such as Marvel and DC. Now for anime, it’s just the short way of saying animation, but in Japan they call it anime instead of animation. Also for those who have watched Avatar: The Last Airbender, yes it’s an anime from Japan, but just with English voice actors.
The Seven Deadly Sins is one of these anime shows that’s in Japanese with English subtitles or just in English. Another thing about anime is that first they’re in Japanese then they add subtitles
