I edited a bit prior to possible help it relate to plot a bit better. Kinda of tie in the spirits to possibly the forest and trees, mainly nature itself in particular. Manifest them into general creatures you'd think of as mischievous, but remain kind of earth bound, if that makes sense. I can elaborate on that further, if need be. As well, I'll change the Limit Break around a bit, maybe tie it in better with his spirits.
