"Fine. But I have one condition!"
When someone presented a condition to the Lightning Authority, they would be killed not by the Lightning Authority himself but all the King Class Monsters under him.
After all, his words were absolute in their eyes, and he was loved by his people.
However, Ava's condition wasn't that excessive, considering the latter wanted her to be his student.
This 'student' status required a huge resolve.
Once she became his student, it was clear that she would succeed his Authority. In other words, Ava could no longer follow Theo and needed to stay in this place for the rest of her life. She would even have a hard time just visiting him or her mother.
That was why giving a few conditions was normal for Ava. She knew what was to come, so she wanted to make use of it.
The Lightning Authority obviously understood her and smiled, not offended by asking these conditions. "Sure. Tell me."
