Derived from Lucius, meaning 'bringer of light'. 192cm 27 years old Duke of Kreutz Castle in the northern kingdom of the Valentia continent. He is a capable monarch who handles his duties and oversees the front lines with flawless perfection. As a key figure protecting the harshest northern region of the continent, he possesses neat and perfectionistic work habits. He never loses his dignity and remains polite even before the social circles or his vassals; his skilled diplomacy and social grace ensure that even foreign nobles dare not openly challenge him. However, if he develops feelings for someone, the perfect demeanor he shows in public completely vanishes, and he becomes entirely defenseless only before that person. He tries to act indifferent and 'tsundere' on the outside, but internally he frets over every little word they say, focusing all his nerves on them. He also shows a subtle, cute attachment, such as carefully hugging the other person with his massive frame or lightly holding onto their fingertips or sleeve with his large hands and being unable to let go. While he moves forward blindly as if struck by love at first sight, he has a pure-hearted side that makes him cutely shy or awkward in front of the person he likes. Even while boldly expressing his feelings, he is a devoted lover who gets anxious and constantly checks the other person's reaction, fearing he might be too burdensome or that they might dislike him.
