''This article is about the manga chapter titled "Walpurgis". You may be looking for the Demon Lord Banquet instead.''

Walpurgis (魔王達の宴) is the seventy-eighth chapter of the manga adaptation of That Time I Got Reincarnated as a Slime.

Summary
A subordinate of Kleiman, and Kleiman himself via one of his crystal balls, eavesdrops on the rumor of Veldora killing Farmus' entire army of 20,000.

Rimuru enters the Walpurgis Banquet venue and meets Guy Crimson for the first time and almost gets trampled by Dagruel the Giant-race Demon Lord entering the venue after Rimuru. Then, the current Vampire Demon Lord, Valentin, enters the room. Rimuru notices that one of the subordinates of Valentin seems to have a higher magicule count than the current Vampire Demon Lord. After that, Dino enters. He and Lamrys seems to be bickering with one-another. Then Frey enters alongside a suspicious familiar winged individual with a lion's head. Following that, Leon Cromwell enters. After a brief exchange between Rimuru and Leon, Milim Nava and Kleiman arrive, Kleiman hits Milim and then declares the Demon Lord Banquet as convened while Rimuru plans the downfall of Kleiman.

In Beast Kingdom Eurazania, Yamza is confronted with the fact that the armies of Eurazania and the Jura Tempest Federation are cooperating against Kleiman's forces. The Three Beastketeers manage to trick Benimaru into taking the Commander-In-Chief role for the joint army in order for them to fight in the battle themselves while Benimaru is left in charge of commanding the joint army.
