general plotting for meeee.
+ Syaoran will recognize the location/etc - he's seen Suwa and personally been to Nihon (and had a fight to the death within the sakura tree!), so he'll get a chance to use that knowledge. He'd know of the creatures, of course, and probably want to advise everyone to keep them controlled.
He'll also utterly freak out at first, given he knows very well what the end to Suwa's miko & guardian was, ha ha ha...
+ Steven has healing powahs and he'll want to save the trees as soon as he's able to - this is a great chance to bring up his mother Rose, as her powers were connected to healing & plants, and if she'd been around, she probably could heal the whole damn thing in one second.
+ Lit. all my priests will also want to fight, save for maybe Steven who is used to fighting in a support mode (so he'd hardly tell the difference, I mean). Charas like Shinah can be useful regardless of fights, given their abilities.
+ I want David freaking out that if he dies holding half of Snow's heart, would that mean he hurts her? Or let's go all the way with the connection and make their suffering connected Sorry Emma.
I'll get back to this when I get more concrete ideas \o\
