I'm gonna try going more 'in-depth' with this week's Black Clover chapter, there's a lot to talk about. While it's a huge info drop, setting up the next arc, there's some possible references and theories to be made, based on the info presented on this chapter.

Now we can clearly see these four Devil's masks, a donkey, a dog, a cat and a rooster. It's far from the first time we've seen Tabata make references to German fairy tales, precisely fairy tales by the Brothers Grimm. This should be a reference to the "Town Musicians of Bremen".

The symbolism behind the tale talks about the peasants revolting against their lords and their regime of servitude. This could mean there's a revolt of classes within the underworld. Lower class Devils rebelling against the Higher Devils.

This could even tie in to Asta's goal.

Possibly more references to the Divine Comedy: Inferno. We have 7 gates to the underworld in one panel, than what seems to be 9 floors (!?) in another panel. This is most likely a reference to the 'Nine Circles of hell' from Dante's Divine Comedy.

We also have 10 Devils matched to the Qliphoth, with Lucifero, the most powerful devil at the very bottom. They should be 10 polar opposites to the 10 apostles of Sephiroth, which were the Elves from the 'Reincarnation Arc'.
