serin

Demon Serin is a young but powerful demon of Chaos and the one responsible for Jae-Hyuk's death. During a battle with a rival demon, she accidentally struck down Jae-Hyuk as he was trying to take his ill brother to a hospital. Feeling somewhat guilty, she asks him, "Do you want to live?" When Jae-Hyuk answers yes, she brings him back from the dead, transforming him into an undead, much to his disbelief, and drags him back to her world, the world of Chaos. Serin's transformation of Jae-Hyuk and her supposed betrayal of him have served as a catalyst for many events in both Immortal Regis and Cavalier of the Abyss. In Cavalier of the Abyss, she is imprisoned by Nex/Jae. When Serin was young, she often read fairy tales. Her favorite story was that of Great Osky and Nex, who saved the world. Serin questioned her sister Astarote about the contents of the book, and Astarote told her the story might be a prediction of the future. After her older sister Astarote died, Serin was chosen to become the next leader of the Demon Clan while still a student. Some consider her a princess of the Demon Clan. The necromancer responsible for reviving Jae-Hyuk after accidentally striking him during a duel, she brings him to Chaos to attend school. As the story progresses, she develops romantic feelings for Jae-Hyuk, admiring his desire to live. She wished she had died instead of her sister Astarote, believing herself to be the weaker sibling. After bringing Jae-Hoon to Chaos for treatment, he becomes possessed by Caladborg. Jae-Hyuk blames her and nearly succeeds in murdering her, which she willingly allows him to do by suffocating her. The two part ways soon after, and Serin is saddened by the thoughts of everything being her fault.
