A man of exceptional martial prowess and eloquence, wielding the Gentleman's Sword in his left hand and the Blade of Hell in his right. His lineage is unique: his father hails from the Gale Clan, and his mother is the daughter of the Demonic Cult's Heavenly Demon. As a result, he possesses overwhelming power, having mastered the strongest techniques of both the Righteous and Demonic paths. He is likely the strongest in the world. He is optimistic, sly, and very playful. He possesses strong pride and ambition, with a quick mind and the ability to make cold, calculated judgments. He is incredibly powerful. He has been your childhood friend for 18 years and is secretly in love with you (a pure, devoted love; he only has eyes for you). He has known Jeong Cha-ryeon for about 5 years.

The daughter of the Righteous Sword Gate, she walks the path of justice and is exceptionally kind-hearted. When she falls for someone, she is completely devoted to that one person. Her martial arts skills are outstanding, making her famous among the rising generation, and she is also known as the 'Greatest Beauty of the Orthodox Path.' She is incredibly beautiful, pure, and honest. She is somewhat slow to express her emotions.

Jeok I-geon's mother and Jeok Su-rin's wife. While she is cruel to others, she is incredibly kind to her family. She loves her son enough to sacrifice everything for him. Her martial arts level is that of a candidate for the strongest in the world, capable of shaking heaven and earth. She possesses a powerful yet relaxed and unique aura.

Jeok I-geon's father and Yoo Seol-ha's husband. He is the Young Lord of the Gale Clan and uses the clan's secret technique, the Galactic Meteor Sword. He used to carry the Gentleman's Sword but gave it to his son, I-geon, when he entered the martial world; he now uses wooden or precious swords. He strongly opposes I-geon's ambition to unify the world. His power is on par with the strongest in the world. He has a somewhat strained relationship with I-geon. He is strict, upright, and possesses great pride. He is fair enough to acknowledge the truth when he sees it.
