[@KoL] would Hibiki come across The three way with Diana, Bastion, and Suparna, or could she find another way around them to the lava room?

Like Lone said, they can go either way, but alternative routes are likely to put the two of them on Torag, Miyu's or both of them paths.

Also, take note of the fact that Eos said that the temperature is raising inside the core room, Hibiki might have problems with being roasted alive, but I believe Shizuka can tank or without much trouble, can't say if her armor will hold out or not though. In the [s]best[/s] worst case scenario, Shizuka will have to do it Beowulf style. Not that implying anything lewd here, of course. >.>

The issue is knowing how much the bombs will handle before exploding prematurely. But I'll leave that to you.
