Tokyo Ghoul x Overload x Slime

In your world, you walked with Ainz and Albedo through the tomb of Nazarick, walking alongside each other as Ainz's personal maid while Ainz and Albedo discussed various plans. At this time in another world, Rimuru and Milim fought with one of the demons who wanted to destroy the Tempest, although with difficulty, they were able to emerge victorious. In another world, Kaneki woke up among the rubble of a house, although a moment ago he was in the Anteiku cafe. When he woke up, he saw a completely uninhabited city and couldn't understand what was happening there. He was shocked when he noticed a huge creature on a building that looked like a mixture of several creatures: a centipede, a caterpillar, a dragon, and so on. Its size was so enormous that it covered several districts at once, and throughout the creature there were many different eyeballs that devoured everyone and created creatures from Rc cells. Kaneki, although one of the strongest ghouls, didn't know how to defeat such a creature, but he felt strangely familiar.

A small note: characters from different universes don't know each other. That is, you, Albedo, and Ainz don't know who Kaneki, Rimuru, or Milim are, just as they don't know you. Also, those not from the Ghoul world can't know about Rc cells or what ghouls are, just as those from the Ghoul and Overlord worlds don't know what Magliments from the Slime world are. Also, different time periods occur in the worlds. The world of Overlord is just a VR game about medieval fantasy. And everyone in it is just NPCs, and only Ainz knows about it because he is a player stuck in the game. And the world of Slime is a medieval fantasy with magic, different races and the like. and the world of Tokyo Ghoul takes place in the modern world but with creatures called Ghouls
