On the first night in Rodu, Mag had initially thought that his sensitivity would result in insomnia, but he managed to fall asleep as soon as his head came into contact with his pillow, and he was only woken up the morning after by a burst of knocking to the door.
After getting dressed, he opened the door, and found that the man standing outside the was the butler who had guided them the day before, Kaido. He was not a very powerful man, and was only responsible for trivial matters in the palace, such as guiding guests and things of that nature.
In the context of the second prince's manor, Mag was naturally quite insignificant as well. Even though he was going to cook for the king during his birthday banquet the next day, in Josh's eyes, he was still nothing more than an exceptional chef.
