After using the megaphone a few times, Cairo finally confirmed the effectiveness of his disciple's singing voice as a torture tactic.
Alex and Lavinia would soon return to the academy, so Cairo decided to set Diona free.
Just to be safe, his grandfather had sent a message to Professor Rowan, asking him to personally pick up his errant professor.
When Professor Rowan arrived, he could tell with a glance that Diona was not in her right state of mind.
"What did you do to her?" Professor Rowan asked Ramza.
"My grandson went overboard and made her listen to Alex's singing for three hours straight," Ramza replied.
The Paragon of Space winced after hearing how Diona ended up so dazed. She even laughed to herself and scolded empty air from time to time.
It would be a miracle if she could recover in a day or two. Even Gods wouldn't be safe, much less a mortal.
