A drone transmigrates as Apocalypse Demoness, Elara Nightshade. Bound to a villain system, she must slaughter the righteous, steal the male lead, and unite the Three Realms, or face soul annihilation. She slacks off: cancels war, orders the demon army to farm! Leader of Righteous Alliance, Aethelred Dawnlight, arrives. She says, 'Guests have come from afar. Let's eat first, fight later!' She out-slacks the system, wins over the Three Realms, and lives a slacker life.
