That Time I Got Reincarnated as a Slime, Vol. 5

Volume 5 marks the end of the Orc King arc and the beginning of the Great Jura Forest Alliance. We got introduced to an interesting Great Sage ability (or rather, “mode”) that wasn't in the anime during Rimuru's fight with the evolved Orc King. Not too sure what to make of it, it felt like an “auto-play” mode. And as the volume wraps up, well, Rimuru ended up giving out names again... a lot of it.
