Rimuru starts to head to Walpurgis (though with his teleportation magic one would think there’d be no further need to “head out” anywhere; he can go wherever he wants instantly and can take whoever he wants with him. But this episode isn’t about Rimuru; it’s about Clayman, his plans, and the elite Demon Lords know and think about all these goings-on leading to the Walpurgis.
Clayman is being set up for an epic downfall. For one thing, he wrongly assumes it was Veldora and not Rimuru who destroyed Falmuth’s army. Second, he still believes his former tool Mjurran to be dead. Thirdly, he took the frankly suicidal step of turning Milim into his doll and puppet by having Sky Queen Frey place an enchanting pendant around her neck. Just to up his evil cred, he beats the everloving shit out of the defenseless Milim. There’s no way he doesn’t pay for all of this somewhere down the line!
Meanwhile, Demon Lords who consider the likes of Clayman naught but a whelp confer before the Walpurgis. Demon Lord Guy Crimson, one of the oldest and strongest lords along with Milim, summons the less powerful but still really really powerful Demon Lord Leon Cromwell to his ice palace to discuss things. While Guy seems content to lounge around his ice palace, a merchant spy (I think we all know who) has been steadily feeding Leon intelligence about Clayman, Rimuru, and Velora.
It isn’t long before Guy’s paramour, White Ice Dragon Velzard, who just happens to be Veldora’s big sister, joins the discussion. These three just emanate power, dignity, and above all shrewdness. They don’t come off as villains, either, but well-rounded people, albeit people who can rend the earth asunder with a snap. By comparison, Clayman and his pack of clowns seem like…well, a bunch of pathetic clowns.
While he could probably only defeat Guy one out of a million or so times, Leon may be the smartest demon lord of them all (most certainly brighter than our dumb blue protagonist), able to see through both Clayman’s lies and the cover story Rimuru put out there. He suspects that rather than being the recipient of tremendous luck, Rimuru could’ve been the one who broke Veldora’s seal, which would put him on their level.
Leon’s even learned that it was Rimuru who cured the summoned children before he could take them in. This makes Leon very excited for the upcoming Walpurgis, though Velzard pointedly declines to accompany him there. No doubt she’s going to go look up her brother in Tempest.
All this lends credence to the fact that Clayman isn’t really someone Rimuru needs to worry about. I mean for gosh sakes, Clayman isn’t even a real Demon Lord yet, while Rimuru is! ‘Nuff said! But it’s not, because as long as people like Guy and Leon are around, Rimuru can’t really take it easy. Aw, who am I kidding, he’s going to keep taking it easy!
