Do they smell like a specific perfume?
The sea?
Utter STANK B.O?
A Plant of sorts, flowers?
Ryu def smells like salt, sweat, and like faint hints of some indescribable nice smell
Like a musky cologne or something manly like that
When he DOES bathe he smells rather nice, that musky cologne smell + the lovely scents of like green tea, sakura blossoms, and other soft smells associated with Onsens
Maya smells mostly like whiskey with a hint of sea salt. Other times you can catch a whiff of wet dog.
She does keep a small bottle of a floral perfume in her quarters though for special occasions.
When she gets super clean though she tends to smell like fresh grass and rain mixed with a hint of cinnamon.
