No one knows King Arthur better than I do

Karl crossed over and came to the royal capital of Camelot, and opened a small restaurant here, intending to live an honest life.
I don't know if people in this place like dark cuisine or they don't come out to eat. There are very few customers in the small restaurant he opened. Only a young lady named Al and her companions often come here.
"Do you think King Arthur really doesn't understand people's hearts?"
"Do you think King Arthur really deserves to be called the Chosen King?"
"Do you think Mordred can inherit the throne?"
Hearing that the eldest lady cared so much about these messy things, although Carl was helpless, he still told her about the money given by the other party.
Finally one day, Arturia, who was aliased as Al, couldn't bear it anymore.
"Boss, I have a showdown, I am King Arthur!"
"What!? King Arthur can't be a girl!"
