Umm...

The information about Malebranche has already been stated above, but I'd like to point out that nothing about the villains of the new arc has been confirmed (at least as far as I know). Based on all previous information available, there's a 99% probability that Indra is in fact the lead enemy, but all we definitely know is that he does appear in the new volume and that he and Shiva will be central characters of the arc. As for Malebranche, that has only been speculation I brought up due to their name appearing on Ishibumi's blog for some time now. Odds are good that they'll make their appearance but it's far from guaranteed.

Oh, and their leader in the Divine Comedy was named Malacoda.
