I remember Indra being mentioned as the villain since before the spoilers for this volume showed up, and seeing the discussion Ajuka and Shiva had in Volume 21 helped imply it.

He's grouped with Loki and Hades in the same area of gods who's actions make things worse for everyone. Loki got sealed so he's gotten his karma, and Hades? He let Rizevim attack Heaven, so now he's lost any way to have privacy and is being watched 24/7.

Indra on the other hand? Nope, karma hasn't hit him at all. He was the one who helped the Hero Faction during their story arc, and they nerfed Ophis which later became outright fatal when Trihexa woke up, as that her left her without the strength to possibly kill it with everyone's aid.

In a way, he's indirectly responsible for all the losses in Volume 21 and the sealing of the various leaders and other powerful figures. It's not that different from how one can say Ddraig and Albion may have basically saved the world by fighting each other and leading to Issei getting the Boosted Gear.

I don't know about everyone else, but at this point I want him to be the villain because he needs to finally face the consequences for his actions, especially since he wants to start a war with Shiva, completley ignoring Trihexa's rampage was the equivalent to a second Great War, but for all factions instead of just the Christian Faction.
