Being this close to them in the first place is causing Uchi pain, as well as yours I'm guessing.

[The Gardevoir looks down slightly, staying near Nagi while Tetris hovers near the crystals. Being a normal type, they aren't bothering him at all, but he's been scouting the field and can see how important they are to these grunts. Whatever the case, that can't mean anything good.

Of course, Nagi is perfectly fine with leaving the crystals as they are, if they weren't causing his own Pokemon to perform inadequately.]

They might not like it, but getting rid of them is the only way to stop that.
