That Time I Got Reincarnated as a Slime, Vol. 9

And Rimuru goes from conspiracy to diplomacy. More worldbuilding at this point (or rather, Tempest-building), as we see the effects of the aftermath of the Forbio/Phobio incident and Charybdis. Tempest is shaping up to be notable power in the region. Lots of lighthearted moments in this volume, which is also one of the things I find endearing about this series in the anime as well as manga. Nine volumes in and truly, there's really not that much missing from the anime.
