Revere Me as a God

Literary version: I have shed my mortal shell and transcended the flesh. In this land of sin, only utter evil remains. Obey my master's command and purge the remnants. O false gods clinging to life in this world, fall to the mortal realm and be sacrificed in these flames.

Comedic version: I tore up the Supreme God's contract of indenture, and now it's blocked me. What do I do? Answer me online, please!

Ordinary version: The story of a polite little madman who takes an emotion-harvesting System to another world and beats up all kinds of reincarnators.
