Zense wa Kentei. Konjou Kuzu Ouji

Known in his previous life as the Sword Emperor, he was a man who dedicated his entire existence to the blade, only to meet a tragic and bitter end. Through an inexplicable twist of fate, he is reborn as the third prince of a kingdom, granted a second chance at life far removed from the battlefield. Determined to leave his violent past behind, he fully embraces a life of leisure, abandoning both swordsmanship and heroism to indulge in pure idleness. Because of his refusal to fulfill any royal duties or display ambition, the public quickly brands him with the derogatory title of "Prince Trash." Yet, he remains entirely indifferent to their scorn, content to while away his days in peaceful obscurity without a care for his ruined reputation. His comfortable stagnation, however, is not destined to last. Everything changes when a fateful encounter thrusts an unexpected individual into his quiet life. This sudden meeting forces the long-dormant gears of destiny to turn once more, pulling the former Sword Emperor back toward a path he believed he had permanently escaped.
