The world Star King Dragon Veldanava created was supposed to get a small unassuming slime with great potential. However, fate seems to be whimsical sometimes and gave the unprepared world a vast dungeon full of beings, both wondrous and terrible. Nazarick, knowingly or not, is bound to reshape the very foundations of the world.

Man gets SI'd into the body of a baby in the year 2100. Turns out he's on Earth, but not just any Earth, Overlord's Earth, a dying planet. With Yggdrasil's release impending, Kakuei knows what he needs to do. Become a player, grow strong, and wait for the game to end. Except things don't always go as planned.

Rimuru Tempest the Slime dies in His world and is Reincarnated as a Human in another world . He starts his Journey to get back to his world and goes through Difficult Situations with Friends on the Way

When YGGDRASIL closed is servers, the famous guild of Ainz Ooal Gown is sent to another world (as the original story suggested). Little did they know, they are now in the Tensei Shitara Slime Datta Ken universe. What will happen in the future?

Under mysterious circumstances, Yggdrasil's shutdown transported Momonga to a world of swords and sorcery that superseded the hard-coded limitations of virtual reality. Cautiously planning and ensuring his survival was vital, but a particular slime's casual approach to things could not help but make the Overlord reminisce about Ainz Ooal Gown's glory days. (Overhaul at end of May!)

With the end of DMMO-RPG Yggdrasil approaching, Momonga decided to spend the last moments of the game reminiscing with one of his guildmates, a player with a slime as their race; Rimuru Tempest. After the shutdown, however, both of them instead find themselves within a completely new world as both they and Nazarick had been transferred to it.

Suzuki Satoru as Momonga finds himself alone in a strange cavern after the end of YGGDRASIL, meeting and accompanying a slime by the name of Rimuru Tempest, he ventures out into the world to spread the name of Ainz Ooal Gown, not only in hopes of finding his guildmates, but also his creation Pandora's Actor. But how will an Overlord of a different world change the future?

Behind their drastically different appearances was a strong bond between Momonga and Rimuru, who had found solace in each other's pasts. And everyone soon realized that whoever got in the way of their shared ambitions, had only two options presented to them: allegiance or death. (DISCONTINUED STORY! WILL MERGE INTO ITS SUCESSOR!)

(This is a repost from my Wattpad account KingChickenyNuggets) walpurgis ended but Clayman said something that slowly starts to reveal a plot older than time itself.

The already eventful lives of Ainz Ooal Gown and Rimuru Tempest was met with more trouble as a mysterious portal-like anomaly connected their two worlds together. What sort of chemistry and relationship would be culminated from such an event?

Peroroncino and bukubukuchagama were teleported to the great jura forest along with Mare and Aura.

No OC's in this story and, if required, Ainz stomping his way forward. Had to somehow actually kill Ainz to start this Crossover. So just go on with it. Overlord/オーバーロード and That time i got reincarnated as a slime/Tensei Shitara Slime Datta Ken crossover. No Rimuru.
