That's grotesque. Yuya just stares at first as the clone seems unperturbed, bunkering under his shield. He can't see the prism, but if the clones are trying to protect it like Gon's, the fire is probably the right way to go.

Thete's obviously someone else here, though, and he doesn't know of anyone with ice powers.

While the clone is distracted, Yuya drops the shield and runs around the clone, aiming for the wall. Maybe if he can get his footing up, he'll see a better route to the prism.
