The stone let out a black wisp, the same wisp that she had seen exuding from Cane's body. If the black wisp was dark magic, then why did it emanate from the stone when she touched it?
And as if answering the question, Haco squeaked to see that. "You purified the stone! You purified it of dark magic! How can you do that?!"
On the other hand, Cane didn't expect something like this to happen either. He remembered the dark wisp that appeared after what Aria had done to him. She inflicted him with dark magic and that was how it started.
But then, Iris managed to get rid of the dark wisp only by her touch. Was that what happened? That was how it worked? She purified him?
"How can you purify it of dark magic?!" Haco grabbed Iris' hand and looked at her closely, as she winced because he hurt her. "How can you do that? It's impossible…" he mumbled to himself. "Who are you? There is no way a runt can use magic."
