Thanks to people in chat for this idea:
This is a rather strange thing to ask permissions for, but: what does your character smell like? Since Amaterasu is currently a wolf, she's been sniffing at people when she meets them.
So! If you have a particular way you think your character smells, post it here! It can be as simple as "she smells like a flowery perfume" or as in-depth as
this. Whatever suits you best! It probably won't be used for anything serious, unless you want it to be. It's mostly just flavor!
Persona 4 characters: Can Amaterasu "smell"/sense something related to your character's Persona? For instance, in Okami Sakuya blesses Ammy with "May the fresh scent of flowers protect you always", so would it be alright if Amaterasu somehow picked up that Yukiko smelled like Sakuya's tree? You can definitely say what Amaterasu would sense, but feel free to opt out as well if you prefer!
EDIT: This is no longer relevant, since Amaterasu is no longer in Hometrail, and in Queen of Hearts she's human and thus not going to be sniffing at everyone she meets (one would hope).
