Battle of the Bubbles - Devilgram
Note: This Devilgram's story content is identical in both "Obey Me!" and "Nightbringer."
"I'll win next time for sure."
Meanwhile, Satan and Mammon are having a shootout when they suddenly get shot by Leviathan in the bushes. He praises his gaming-polished stealth skills, and then goes to find MC. They find each other in the woods and begin the final showdown. If MC chooses to flank him, Leviathan outmaneuvers them and they lose. If MC attacks head-on, they take him by surprise and win. In the end, the two clean their guns in the bathroom. Leviathan is happy they used all the liquid while getting to use the guns he bought, and asks to do it again sometime.
