As the light flickered out, Rin returned to his more attractive form.
Cairstiana put the tiara back in his satchel.
"Can you explain this to me?" Cairstiana asked.
"I don't really understand it myself." Rin said. "Gehenna, the world that your 'Father' came from created magic with the nectar of a garden of sunlight flowers, cultivated by Yuri, the Priestess of Life and Death. Eventually they got greedy and there was only one left. I was one of Satan's sons, me and Yukio. That tiara was our mother's. You are human, however. Just a girl. I dunno know why you are able to use demon power."
"Aren't I a demon?" Cairstiana said. "If Father is, I am!"
Rin leaned in. "Nah. You don't have a single drop of demon blood. But you do have magic. In your hair."
"I know that. I always have." Cairstiana said. "He makes me sacrifice humans for his youth. I always wanted to save someone. Demon Prince! Please, give me this tiara!"
Rin shook his head. "Not a chance."
"Please I can save people." Cairstiana said.
"That tiara turns me into a monster. I don't want that to happen again." Rin said. "I'm going to seal its power and then sell it and continue on my merry way."
"You can't!" Cairstiana said. "I have it!"
"And I suppose you want something from me?" Rin said lazily.
"Yes. Freedom."
Rin's tail wagged in anticipation.
