After she closed the door, Kalliope didn't go away directly. She stood in silence in front of the principal's office. Her expression was deep in thought as the old man's last words floated in her head. Though he had brushed her off at the end, she had heard it loud and clear. He mentioned pureblood.
And Kalliope only knew one group of people who were called such a term. It was the first generation of the chosen ones who were blessed by the great spirits but were chased out by the very humans whom they had protected from the demons' invasion.
Although it felt impossible but Kalliope couldn't rule out the small percentage of him knowing about the "real" history. After all, the principal was well aware of the demonic presence lurking on Earth at the moment. So, Kalliope couldn't stop herself from suspecting the principal even more now.
