The four of them finished their meal and fell into silence which was broken by a burp from Alexandra.
"Sorry," Alexandra said as she rubbed her full stomach.
"It's fine," the Demon King said as he smiled. "But I suggest starting to study noble etiquette and royalty etiquette."
The Demon King whistled and suddenly a portal opened. From inside the portal comes out a vampire butler who looks so charming and elegant.
"What's wrong, Your Highness?" the vampire butler asked the Demon King as he was kneeling beside him.
"I want you to teach this dragon a lesson about noble etiquette and royalty etiquette," the Demon King said as he looked at Alexandra. "It is very important for her to learn both because from now onwards she will be my right hand."
"Then what about these humans, Your Highness? Do I have to take care of them like the others?" the vampire butler asked.
"No, from now onwards they are my children," the Demon King said.
