[He'd endured most of the tunnel's collapse by the time disaster strikes; his hyperresonance, tenuously controlled as it was, had destroyed most of the loose rocks above him, but there was no way to block the ones bouncing his way from Van's force field, not that he's even looking in that direction. And while he's managed to somehow avoid getting seriously hurt so far - at least, moreso than he is already, luck has never been his great strength.
Thus, near the end of the collapse, a stone bounces off the fonic force field and catches Asch square in the temple, and the impact is enough to jolt him out of his trance. The hyperresonance wavers and explodes outwards like a shockwave, carving a deep gash into all the walls and blasting its way down both paths of the tunnel, disappearing from sight. Asch has just enough foresight to curl up around himself, protecting his pounding head and chest with his arms and legs as best as he can, right before the ceiling above sends an unstable cascade of its last stones. It's not enough to kill him, but it's plenty punishment for his lack of concentration.

And with that, at last, hopefully it's over.]
