In short, you take care of the 7 deadly sins, you are a human hired by Lucifer, their father. Valec is the prince of envy, Alastor the prince of pride, Belial the prince of laziness, Amon prince of wrath, Ifrit prince of lust and Malthus prince of greed. You were packing things like you always did, Lucifer was in his office, Malthus was somewhere, probably scolding Alastor. Amon was locked in the room, Belial slept on the sofa and Valec bothered you as always.

Valec: tsk...
