Lucario looked to the princess and nodded, acknowledging her. He was quiet for a few seconds, as he usually was before responding. It certainly didn't help that he didn't exactly sleep well at night for the past month, as he was always alert for signs of assassins after getting appointed the royal guard for the princess. 

[i]"Good morning, princess. I hope that you slept well?"[/i] Lucario asked after the few seconds had passed. His tone sounded alert, despite his exhausted state. 

As loyal as he was to the royal family, he often wished that the king had appointed more than one guard to protect his daughter. That way, Lucario could get some much needed sleep when the other guard or guards were on duty. Hoowever, most of the residents knew better than to question the king, who was nicknamed Ironfist for a reason. The king was usually forgiving on certain things, but one wrong move could end up costing someone their head.
