That Time I Got Reincarnated as a Slime (Original Japanese Version)

A feast is thrown to celebrate the revival of Tempest's fallen and the return of Veldora. After enjoying a brief respite, Rimuru tells everyone his future plans: he's going to get the word out that he's a Demon Lord and declare war against Clayman.

As prominent figures from several nations assemble in Tempest for a meeting, Laplace and his companions formulate a plan centered around Clayman. Then someone familiar joins the discussion...

Rimuru and his companions shift their focus to their imminent confrontation with Clayman.

Ramiris is summoned away from the assembly to meet with Clayman and the other demon lords.

Rimuru concocts a risky plan to deal with Clayman and his army.

Rimuru succeeds in outwitting Clayman by transporting all of Eurazania's refugees to Tempest. Since Clayman has been striving to evolve into an Awakened Demon Lord for a long time, his resentment toward Rimuru grows.

Walpurgis draws near while Rimuru’s forces launches a cunning surprise attack.

Gabiru narrowly wins his battle against Hermes. Watching their outcome is Middray of the Dragon Faithful, whose skill was enough to overwhelm even Suphia.

Rimuru attends Walpurgis while his allies make their way to Clayman’s castle.

Clayman tries to convince the other Demon Lords that Rimuru should be purged, but Guy tells him that if he is truly a Demon Lord, he should defeat Rimuru himself.

Clayman and his pawns stand no chance against Rimuru and his allies. At a loss, Clayman orders Milim to use Stampede to kill everyone present, but Milim reveals he was never controlling her from the start. It was all an act to expose Clayman's plans!

Rimuru backs Clayman into a corner trying to get him to reveal who he's working for, but even on death's door, Clayman's lips are sealed.
