Il-Hwan Seong

Sung Il-Hwan is the father of protagonist Sung Jin-Woo, a man who once served as a firefighter and became recognized as the earliest S-Rank Hunter to awaken in South Korea. He vanished during a dungeon mission a decade ago and was presumed dead, yet the truth was that he had been selected by the Architect as a vessel at the very brink of death. Returning to the human world in the second season with orders to eliminate a new Monarch, he ultimately defied that mission upon facing his own son—the Shadow Monarch—choosing instead to sacrifice himself to protect his family. He stands as a powerful yet profoundly tragic heroic father.
