Aaron slept longer than usual and woke up near noon. He was tired from the training, and after that, he was electrocuted during the ritual. His body needed rest, so he didn't wake up from bed till noon, except for a brief moment when he woke up to eat breakfast.
Though his body needed rest, an empty stomach wouldn't help his body much. The body needs energy to help it return to the peak stage. Food may be the slowest way, but it is the best way to do so. So, he had to wake up for a brief moment before going back to sleep.
At noon, he woke you, refreshed before cooking and eating lunch. After filling up his stomach, Aaron left for the Dungeon Hall. From that day to the day he would leave for the tournament, he would be levelling up, so that he could improve his luck value.
