If you loved Dragon Ball - L’Aventure mystique, try One Piece, film 5 : La Malédiction de l'épée sacrée
Un pont entre un film que tu as déjà vu et un que peu de gens ont croisé. Voici ce qu'ils partagent, et ce que le second fait que le premier ne fait pas.

Dragon Ball - L’Aventure mystique

One Piece, film 5 : La Malédiction de l'épée sacrée
Ce qu'ils partagent
Both films are directed by Kazuhisa Takenouchi, and they both carry the playful mood tag, and they sit in Action / Animation territory. If that's the register that drew you to Dragon Ball - L’Aventure mystique, the second film will land in a comparable space — through a different lens.
What One Piece, film 5 : La Malédiction de l'épée sacrée is
In a fishing village near a sealed shrine, you guard the Seven Star Sword whose legend brands every thief cursed. When Marines storm the coast, your crew vanishes but Zoro stays behind, sword in hand, eyes empty. You spot him fighting his own past when a face from his swordsman days reappears—Saga, now leading the charge.
