Meliodas, the sin of wrath. Ban, the sin of greed. Gowther, the sin of lust. King/Harlequinn, the sin of sloth. And princess Elizabeth of Liones. These five have embarked on a journey to save the kingdom. They search far and wide for the two other sins, pride and gluttony. But what about the eighth sin, the sin of burden? Don't make the mistake of thinking she is a burden to the sins. That is not why she was given this name. She is the sin of burden because she always tried to handle everything herself. Not out of pride, but because she wanted to seem useful and make sure the others didn't get hurt. What will happen when this phantom sin joins her counterparts?
