Reira sadly doesn't have the option of oozing and hiding her soul like Eruka is; the most she has is curling up and staying as still as she can. As quiet as she can.

Maybe if she tries to feel like what she's meant to feel 'becoming wind'- maybe that will help.

(It absolutely Won't, but she's going to at least focus on being as one with the surroundings as she can at this point)
