"Oh no you don't-" He slams a foot forward right into the middle of the door as Axel tries to slam it shut. That actually hurts more than he's used to, which he'll blame fully on Axel for having a twig of a body and poor food choices. Saix will keep kicking at this door too, until Axel opens it. Little spurts of flame are erupting around him. At least they're sticking to air, instead of lighting the house on fire. Or Roxas.

Speaking of... He pauses in his violent assault on the door, boot still raised up and leaning on it, and glances to Roxas. "No. I thought it would be easier to just get us here instead of explaining. Now someone just has to open the door-!"

BANG BANG BANG BANG.

Don't make him break this thing down, Axel.
