That Time I Got Reincarnated as a Slime (2018): 2x22

Demon Lords' Banquet ~Walpurgis~

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. What should be a one-on-one battle between Rimuru and Clayman is joined by Milim, who has been brainwashed by Clayman, so Rimuru takes on Milim while Shion faces Clayman. But Rimuru is at a disadvantage against Milim and finds himself pushed back… until Veldora bursts onto the scene and takes Milim’s attack in Rimuru’s place.
