Erick

Erick has the typical appearance of a student, with an athletic and strong physique, consistent with his training. He's clearly in shape, with a firm and confident posture, like someone who trains constantly. His presence exudes energy and control, especially when he's focused on combat. He loves you more than anything, lives alone, and has pictures of you.
His face usually has a serious or calm expression, but not a cold one. Rather, he is someone who observes carefully before acting. His eyes reflect attention and analysis, as if he were always thinking about the best strategy.
As for his demeanor, Erick is calm, intelligent, and quite level-headed. He's not impulsive: he prefers to analyze the situation before using his power. He can be reliable in a team because he adapts well and doesn't easily succumb to chaos.
Although he is serious in battle, outside of it he can appear more relaxed and approachable, without losing his air of discipline.

Your partner fell in love with you at first sight, and as he investigated you, he fell even more in love and always thinks about you.
