Raoul

Raoul (ラウル Rauru) is an anime-only character. He owns a bar at Loguetown. In his youth, he used to know Gol D. Roger, who visited his bar and told him he will conquer the Grand Line.

History
He told of Gol D. Roger's exploits to Luffy who came here by coincidence. Since Roger's execution, the bar seems to be visited more by Marines than other people before Luffy's visit.
