Well if you like anime and you know it well I don't need to tell you where this story comes from. If I tell you this, then you will remember. Meliodas the dragon sin of wrath. And Ban the fox sin of greed. Oh............. what's that you dont who where this comes from well then............in that case you need to GET A FUCKING LIFE. Jk. But in all seriousness this story is based off of one of my favorite animes called The Seven Deadly Sins.
