Arthur went straight home.
There was no one there except the guards and servants. Isabel still hadn't come home, she probably came home quite late.
Arthur went to the roof of the house, sitting on it with his legs crossed.
There, he took out the black sword given to him by the mysterious being.
He was actually wondering if he needed to swallow the sword now.
When talking about becoming a God, he naturally wanted to as soon as possible, after all, he had basically lived as a Great Magus for a long time.
He missed the sensation of having much greater power.
If he waited for Isabel to come back and chat with her again, he was worried that it would disturb his mind.
After a while of thinking and seeing the sky getting darker, he finally decided now.
Whoosh!
He flew into the sky at high speed, breaking through cloud after cloud.
