Amelia understood why Killian was asking her and Chrysanthe this question and was aware of its implication. However, Amelia would never abandon Iris, despite their circumstances.
"I'm already part demon, Killian. Do you really think oblivious humans would welcome us back with open arms? Iris wasn't the only one who lost her family to them, but me and Chrysanthe as well. Returning to the human realm would warrant our deaths."
Chrysanthe nodded in agreement. She was starting to lose sympathy for humankind. Though she knew there were rare decent human beings out there, they were outnumbered by those with ill thoughts and intentions towards magus and humans related to the darklings.
"And there's no reason to return to the human realms. I have no one aside from Iris and Amelia. I would rather stay where they are, no matter how dangerous it would be." She reasoned it out.
