An Overlord and aSlime?

[OC] - At the very end of YGGDRASIL, Momonga was transported to a completely new world. He was not alone in these confusing turn of events as he happens to encounter Rimuru Tempest, a slime who had a similar fate. The Overlord had first thought of taking over the world as Ainz Ooal Gown in an effort to find his guild mates, but the slime has different ideas on how to play this out.
