One Piece: The Dragon Knight of the Grand Line

Reborn in the world of One Piece, I, Karl, was granted a unique “Gacha” System. Every five years, I get to smash a golden egg and pull a legendary prize. At age 5, I pulled the [Infinitely Evolving Monster Body]. As long as I keep eating, I keep getting stronger. The seas would soon fear another monster like Big Mom. At age 10, I pulled the [Sealed Mystical Spear]. A weapon capable of converting my stamina into a beam of pure light, capable of annihilating anything in its path. At age 15, I pulled my greatest prize yet. A card from another world... the legendary [Blue-Eyes White Dragon]! At age 20... the world was no longer ready for what I would become. My legend begins in the East Blue, but my destination is the heavens. They call me a pirate, a monster, a king. But my true title is... The Dragon Knight.
