One Piece: The Dragon Knight of the Grand Line Novel

Karl awakens in the One Piece universe, wielding a rare Gacha System that grants legendary rewards every five years when he shatters a mystical golden egg.

At five, he obtains the [Infinitely Evolving Monster Body]—a blessing that transforms sustenance into raw power, positioning him to rival even Big Mom's monstrous strength.

At ten, fate delivers the [Sealed Mystical Spear], an ancient weapon that channels his stamina into devastating beams of pure light capable of obliterating anything.

At fifteen, destiny shifts dramatically with the [Blue-Eyes White Dragon], a card from beyond his world that reshapes his entire existence.

By twenty, the seas themselves tremble before his ascension.

Beginning his journey through the East Blue, Karl's path leads toward the heavens themselves. Legends brand him pirate, monster, and king—yet none capture his true essence.

He is the Dragon Knight, and his reign has only just begun.
