Yuriko

These are the concepts in a Chat in Discord:

....so that would mean she would have to ask for Demon training after quitting her day job?

She could forage easily; and would be civil towards Inosuke

Offer food since she's encroaching on his territory

She can easily praise his hair and blue clothes. "Did a quality tailor make this?! I'm envious!" 

She'd be impressed for sure and give him a willing audience (After seeing a gif of him contorting)

I can see it: If she's a courtesan, she can play the shamisen and entertain him

And make sure he's given good food/sake/sweets

Shopkeeper: She'd reserve the items he likes for him; She could take advantage of the acorns and plant them/make crafts
