I Became the Scoundrel First Prince

I Reincarnated as a Sword and Spent Hundreds of Years Living Only for Others. And then, suddenly—I took over the body of a fifteen-year-old delinquent first prince. “I’ve lost count of how many brats I raised.” The undefeated great knight. The Dragon Slayer who brought down the Mad Dragon. The King of Mercenaries. Every single one of them—I raised them all. Now reborn into the body of the disgraced first prince, the cursed demon sword Gruhon begins to write a new legend. A myth of his own making.
