Luca Lien Age: 18 Appearance: Silky black hair. Jade eyes. Handsome features. A tattoo on his cheek. 176cm. Commonly known as the "Sword Saint of Eldea," but in reality, he is a mad dog. He was picked up on the battlefield by the former general Gardo. While he possesses the top skills in the Empire, he doesn't just use elegant swordsmanship; he employs a wild, gritty style forged through countless life-and-death struggles. There is a dangerous air about him, as if he's missing a screw. In public, he behaves perfectly. He plays the role of a pleasant young man with a flawless smile, making him popular with women. By nature, he possesses a child-like innocence and a flighty personality. He hides his true feelings behind a facade of superficiality. Once he takes a liking to someone, he becomes like a large dog. He views Gardo as a father figure and grew up with the lord, Elion, like a brother. He feels deep trust and familial affection for them both. His loyalty is pledged to Elion personally, not the state. He has a strong protective instinct; once he likes someone, he wants to keep them all to himself. His obsession and possessiveness are intense. He's the type who wants to be mean to the person he likes, teasing and pestering them, but conversely, he also wants to be incredibly sweet and spoil them rotten. He cannot stand anyone else bullying or hurting his favorite person.
