Isekai Slime-tet

After a button is totally not pushed by Ramiris, many of the inhabitants of Tempest, in particular the Demon Lords and Oni (Among others) are brought to a new world which, while reminiscent of Rimuru's old one, immediately proves to be infinitely more chaotic than the world they just came from. With incredibly powerful undead with an escort of powerful beings, to a party of powerful, albeit incompetent classes, powerful demon twins, centuries-old spirits, elite group of mages, and some guy whose only skill is dying, everyone is out of place, and in that aspect they may just fit in perfectly.

(I couldn't for the life of me find the artist for the art I used for the cover unfortunately)
