It's still no pleasant to look at the second time, but Yuya reminds himself these are definitely not Rin--and while it's down, he turns his attention away and rushes to the edge of the building to look down at the prism, and the wall of fire surrounding it.

Yeah, he definitely needs something stronger than his foot. He usually can't move his shield while moving, since it focuses around him... but maybe falling would be different? It's not because his concentration is breaking to move after all. He doesn't have anything else to hit it with, anyway.

Yuya sucks in a deep breath to steel himself, squaring his shoulders. And then he jumps, kicking off the roof as he dives for the prism. In the middle of the air he pushes his shield out--

But it only holds for a second before he crashes into the opposite side of it, breaking the barrier, and then narrowly avoiding impaling himself on the top of the prism as he slams into it and tumbles off the sloped roof. He falls to the ground, hitting it soundly and dangerously close to the inner face of the flame wall. He rolls over slightly, groaning in pain.

That didn't work at all.
