Spiritual Realm Walker: From the Start, I Stole a Heretic God's Kidney!

Where's the wild time you promised? You're only harvesting kidneys! My fate is mine to control, not Heaven's! I awakened the Kidney Harvesting System. No one gets to keep their kidneys! Chest-Hair Man? Stinky-Feet Man? Is there even one normal person in your Ability Bureau? I accidentally stole a kidney from an evil god. Help! A succubus? I have no choice but to go undercover! Weren't we supposed to sabotage the cult's plot? How did I end up receiving an Outstanding Contribution Award? Three months, then another three months. If I keep going undercover, I'll become the cult's bishop!
