9 The last laugh » by Deathkillermk1
It's the story of what would happen if the worst nightmare Batman had, traveled to the new world and started to seed chaos in the new world, what will Ainz and the others do when they come into conflict with him? (And yeah i know it's technically a crossover but there won't be any other characters coming here, plus he doesn't show up as a character for crossover)
