The son of the Duke is known to be a reserved person, and can even come out as self-effacing or standoffish at several occasions.
Lewis grew up sheltered for the rest of his childhood, but even then, he's far from gullible and naive when it comes to how the world truly revolves. As the sole successor, he was trained to become the fiercest and most competent swordsman among their house's Cerulean knights. He is also the most erudite scholar of the empire's cream of the crop - faultlessly raised to be the fine and outstanding young noble that he is today, overall.
If there is one thing that Lewis lacks, which is quite overt to the eyes of many, it will be his dispassion or impassivity when it comes to socializing. He isn't one to display interest in such matters, though he is still a courteous gentleman with a refined set of social skills just like the many others.
