“She was originally a demon. How could she be led evil after meeting a human like me? Those critics always say some ridiculous things.”

In 1798, during an interview with a reporter, Cardinal Ranchi was asked about his past with the exiled princess of the last descendant of the Demon Clan and the recent signs of the Demon Clan’s recovery. He said:

“I have made too many efforts to safeguard world peace. I am convinced that under her leadership, there will be no chance of the demons returning to the country.”

…

In the winter of 1802, the demons successfully restored their country.
