I, the Donquixote Family's Great Swordsman

After transmigrating into the world of One Piece, he becomes the young master of the Donquixote Family and the eight-year-old cousin of Donquixote Doflamingo: Donquixote Luke!

In this dangerous family, Luke is understandably on edge.

Fortunately, the sign-in System activates!

Doflamingo: "Hey, Luke, how about going easy on me? You keep beating me to a pulp, and it makes me look bad as the young master!"

Luke: "Oh, my foolish brother. See that sea in the New World? That's the water I let go."

Sengoku: "Having one Doflamingo in the Donquixote Family is already a huge headache. Who could have imagined they'd produce Luke, a monster countless times more terrifying than Doflamingo? And the worst part is, he's only eight! An eight-year-old master swordsman!"

Hawk-Eye: "When it comes to swordsmanship, I can only take second place in front of Luke."
