Okay, so Very Soon after the audience, after Hajime has killed Mifeng, Masshuu will be killing Hajime in a big fiery battle on top of the roof. And then basically setting a good chunk of the palace on fire. He'll only do the top levels here, but the next day when he comes back to help with break Ridou out he'll attempt to set the rest of it on fire behind them.

It will also be really obvious that he was the one that did it too, because all of the fire will be blue.

Anyhow, I think there are also a few other Palace Destroying plans about, so we could work those out so that everyone collectively brings this thing down?
