Regressing As The Reincarnated Bastard Of The Sword Clan (Korean: 검술명가 서자의 회귀) is a high-octane standout in the "Regression" and "Revenge" genres. Written by Nok-A and illustrated by Gom-Guk, the series is celebrated for its visceral portrayal of martial progression and its darker, more tactical approach to the "Swordmaster" trope. It distinguishes itself with a relentless focus on the psychological impact of the protagonist’s past, creating a narrative that is as much about reclaiming lost dignity as it is about absolute domination. The series is world-renowned for its sharp, energetic art that perfectly captures the intensity of high-stakes duels and the cold ambition of its lead character.

The story follows Raon Zieghart, a man born into the prestigious Zieghart family only to be discarded as a "bastard failure." In his first life, he was kidnapped and spent decades as an assassin, a "dog of the shadows" forced to commit atrocities for a cruel organization. After dying a tragic death, Raon is unexpectedly sent back in time to his infancy within the Zieghart clan. Armed with the lethal instincts of a master assassin and a cold, burning hatred, Raon embarks on a second life. His goal is simple: to seize the power that was denied to him and destroy the institutions—both family and organization—that sought to use and discard him.
