In the Nocturne Kingdom many years ago there has been a prince named Akito, which fled the castle. No one could ever find him and the kingdom had no other heir to the throne. The king and king had another son named Toya. He never got to know about his long gone lost brother, since it was decided that he mustn’t know of him - to avoid a potential problem. It was forbidden to speak a word about this runaway prince, so the whole topic faded away quickly.

After many years Akito’s life changed, so did his looks. He applied to be a royal knight ever since he heard about him having a little brother. He didn’t want to be away from the new heir and keep him safe at all cost. Heck, he even got the chance to be the prince’s guardian! Akito never mentioned one word of his parents nor where he lived - he only made up a lie in front of the royals to get the job.

Now he was on his first day and was presented to Toya himself.
