F-Class Destiny Hunter

In a world governed by destiny, where abilities are awakened based on one's fate, Seo Gangrim is born with the lowest possible destiny rank. Despite awakening as a hunter, he finds himself at the very bottom. During an attack, his F-class destiny proves to be a cruel miscalculation as his power, 'Destiny Theft', activates. This event grants him the 'Regression' ability, allowing him to return to the past moments before his death. Having witnessed his entire team fall to a killer, Seo Gangrim resolves to defy destiny and forge his own path. The story incorporates elements such as destiny manipulation, evil gods, game-like mechanics, divine beings, magic, a male protagonist, monsters, a second chance at life, skill assimilation, swordsmanship, time travel, and a progression from weakness to strength. The novel's content is adapted into a manhwa, with chapter 55 of the manhwa corresponding to chapter 92 of the novel. Discussions suggest that 'Destiny Theft' is an S-class ability, contrasting with the protagonist's initial F-class hunter qualifications which were hindered by a lack of mana. The title's "F-Class" refers to the protagonist's hunter rank before his regression.
