He's innocent, quick, honest and perhaps a little too harsh.
This isn't surprising considering for someone with his position.

He was born in a small family in an important capital.
He lived free of worries until he was about 18 years old,
but at that point things began to change.

He started to travel a lot and was slowly improving upon existing skills.
With amazing new friends, he managed to thrive in a outlandish world.
But with his powers and wits, there's nothing to stop him from doing anything.
He could quickly become somebody we can expect great things of.

But for now that's speculation; he is currently enjoying the world and its beauty.
He feels like there's more to explore in this world.

Luckily he has awesome friends to support him.
