"Here." Octavo shoves a glass jar filled with an opaque, pale blue substance in their face. A label on it reads SPIRITUAL CONCENTRATE. "I found this in one of the markets here. The shopkeep told me it's for people who eat spiritual energy and such. There are no real ghosts here so it's the best I can do. Can we call this off, now?"
The demon was going out of their apartment to throw out something before getting a bottle in their face, barely noticing the guy. They used their tail to snatch it, if it was something holy it at least wouldn't melt their face when opened. They seemed tired.
"Geez you're forward. Hold on."
They inspected it for a moment using their tail to moving it around. It seemed legit and they weren't feeling nauseous around it. So... He pop'd the cork from this thing with their claws and shoved the contents into their mouth.
Suddenly the inner heat inside their body started to glow brighter before settling down again.
Ama looked delighted and seemed to have a pep to their step in contrast to the disheveled look they had before.
"OH THAT HITS THE SPOT!"
They jumped over and gave the man a smooch on the cheek before happily backing off.
"Thank you ! Who was the merchant??"
