A Dragonslayer's Peerless Regression (Korean: 용살자의 무쌍 회귀, RR: Yongsaljaui Mussang Hoegwi) is a high-octane action-fantasy manhwa written by Suga and illustrated by Gom-Guk. The series is highly regarded for its gritty atmosphere and its focus on a veteran warrior's psychological burden as he tries to prevent the literal end of the world.

The story begins in a desolate future where humanity has been wiped out by catastrophic dragons. Sion, the strongest and last remaining Dragonslayer, manages to slay the final dragon king, but finds himself alone in a world of corpses. Upon his death, he regresses to his teenage years—long before the dragon invasions began. Armed with "Dragon Sense," peak combat techniques, and the knowledge of every hero who fell, Sion is determined to change destiny by perfecting his body and gathering his former allies before the sky falls once again.
