Age of Discovery: Summon Heroes and Build the Strongest Family

He transmigrates to the world of One Piece and becomes Robin's father. Duke obtains an Alliance Shop System,

which lets him spend Devil Fruits to draw League heroes, equipment, skins, and more!

Years later, he looks at the people standing behind him: Garen, a Marine Headquarters admiral; the newly crowned Emperor of the Sea, Gangplank; Swain, the ruler of Noxus, a superpower of the Grand Line;

as well as the Scarlet Baron, one of the Seven Warlords of the Sea,

and the Revolutionary Army's Saintess, Soraka, along with other heroes.

Duke gently says to Robin,

"I don't care about so-called history. But if you want to,"

"you can be history!"

"Because I'm behind you!"
