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.

Not out of pride, but just 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?
