The Third Prince of the Fallen Kingdom has Regressed is an action-fantasy manhwa by Lee Jung-min and illustrated by Studio Inus that follows Prince Yuri Briol, the unruly third prince of the fallen Briol Kingdom. After dying in guilt-ridden exile, Yuri regresses to the spring of his 13th year — just before the Empire's devastating invasion — determined to rewrite history and save everything he once lost.

What sets this regression manhwa apart is its sharp focus on honor, consequence, and the weight of foreknowledge. Armed with memories of a tragic past life, Yuri must navigate ruthless nobles, an overbearing father, and the looming shadow of war. Rooted in classic isekai-adjacent fantasy and adventure storytelling, the series explores how one prince's resolve — shaped by the motto 'Briols do not abandon honor, even in death' — can turn the tide of an entire kingdom's fate.
