Ross City is a no-fly zone for humans, meaning they cannot fly through the air without using an automobile or jet. Despite thousands of Saints and Sages living in Ross City, none have ever flown through the sky.
Because of this, Klaus and Ohema didn't make it to Ross City by flying. They flew for a while, but when they were a few kilometers from Ross City, they had to land and walk. It took them just a few minutes to reach the eastern city gate, where Kofi was waiting for them.
"Young Master, My Lady, this way please," Kofi said, opening the car door for Klaus and Ohema to enter. Klaus made sure Ohema entered first—signs of a gentleman.
"Kofi, I see you've been spending too much time with Henry; he seems to be rubbing off on you," Klaus joked as they started moving.
Kofi smiled slightly, hearing his Young Master say that.
