Chun Hwi

Chun Hwi was the previous Heavenly Demon, leader of Cult of Heavenly Demon.

History
Chun Hwi's wife passed away while giving birth to their daughter, Chun Ah Young. The Heavenly Demon wanted his daughter to have a normal life, however she chose to enter the Cave of Latent Demons and underwent grueling training for ten years, which has a high turnover rate.

Among the survivors of the Cave of Latent Demons was Hyuk Woon Sung, who quickly established himself as the strongest of his batch and rose swiftly through the ranks with his strength and merit. Chun Hwi was impressed with Hyuk Woon Sung's performance. After learning that he had been poisoned with an unusually strong poison, and that his condition was terminal, Chun Hwi took Hyuk Woon Sung as his first and last disciple and began to spend his final months grooming him as the next Heavenly Demon. Hyuk Woon Sung inherited the Divine Arts of the Heavenly Demon from his master. In the meantime, Chun Ah Young was unexpectedly chosen as the new Divine Maiden by the Divine Flames of the Demonic Cult. During Ah Young's ceremony, Chun Hwi began to succumb to the poison and was bedridden. Meanwhile, internal conflict erupted between Hyuk Woon Sung and the vice-leader, Joo Moon Baek.

Eventually, Hyuk Woon Sung and Joo Moon Baek battled when the latter and his followers had attempted to kidnap Chun Ah Young. Chun Hwi arrives and kills Joo Moon Baek and his followers. However, he was stabbed by "Ghost" who was possessed by Hwan Dok. The dying Chun Hwi took Hyuk Woon Sung to a private chamber and used his final moments transferring his battle experiences and his remaining power to his disciple. Six months later, Hyuk Woon Sung stabilizes his new energy and enters the Divine Realm. Chun Hwi's funeral was performed, and in the wake of that event, Hyuk Woon Sung became the new Heavenly Demon. Realizing that Chun Hwi was poisoned by the same people who poisoned his other master, Nok Yu On, the new Heavenly Demon swears vengeance for his two masters.
