"What?" Catherine's eyebrows jumped.
"I could barely notice it. Calamity was sharper than me. Even though I can beat her in a battle, she's still better than me, huh."
"Not that, why didn't you arrest him?"
The Dean looked at her and shook his head. "If someone can sneak into this academy, he's either reckless or confident.
He must be using a treasure for his disguise. An excellent treasure, since only Calamity and I found the truth.
But he's also using another treasure. A treasure to hide his age."
Saying those words, the Dean's mood turned complicated. "I did my best to check his age without him noticing. It always came out to be 19. A 19 year old."
Catherine parted her lips to say something but in the end, she sighed deeply. "So he's an Empire's genius, huh."
"Yes, only they have such treasures. For my power to fail even after so many tries, it must be from a divine ranker." The Dean's voice was filled with longing and sadness.
