[Adventures in the Roger Era] + [Gunslinger] + [Pure Devil Fruit Development] + [No System] + [Unchanged Power Levels]

Darrow travels to the world of One Piece and becomes the younger brother of Roger's wife Rouge. Fortunately, Roger has not yet conquered the Grand Line, so Darrow still has time to change his sister's tragic future.

With the power of the Compression Fruit and his innate Observation Haki, Dead Eye, Darrow grew step by step and made a name for himself on the high seas, writing his own legend in an era where heroes like Roger, Rocks, and Whitebeard rose to prominence.

The story begins with the crew's adventures (partially original storyline + extensive references to the old era in the manga), and after Roger's death, they become one of the Four Emperors and vie for supremacy.

A novel revolving around being transported to another world with an op system. The mc spends his day chasing skirts and doing missions to level up. A standard journey to the top with lots of girls from various animes and games with a twist of that gaming feel (hunting mobs, doing missions).
