@B214 Yeah, Vali absorbing Malacoda seems like a more likely scenario. I just though that since Ise will use the 12 Heavenly Breasts to reach his ExE form (presumably), Vali could use the 12 Malebranche to reach his own version of it since these two emulate each other in some regards.

@Merkarion The spoilers for Zero said Malacoda 'can never be awakened', but doesn't specify whether that means it's impossible to awaken or extremely dangerous to do so due to its power. There was also a line about the other heads of the houses under Lucifer needing either Lucifer's permission or Lucifuge's permission to unseal the Malebranche, so perhaps only members of thiose families can fully lift the seal on all 12. Supposing that's the case, Euclid might return in this arc, unsealing the Malebranche to fight for Hades and his faction. Since Sirzechs is sealed in the Isolation Field, Euclid could be persuaded to help Hades in exchange for obtaining Grayfia. I think that would be interesting, but only Ishibumi knows what'll happen next.
