The Wano Country arc is the current and ongoing arc in the One Piece anime and manga series, and as of April 2023, it has not yet concluded. Therefore, it is impossible to definitively say which arc comes after Wano at this point in time.
However, there are some hints and clues that suggest what could potentially come next in the series. One of the biggest clues comes from the fact that the creator of One Piece, Eiichiro Oda, has stated that the Wano arc will be the “climax” of the first half of the series. This has led fans to speculate that after Wano, the story will shift towards the second half of the series and explore new plotlines and locations.
Additionally, there have been a few hints dropped in the series that could potentially foreshadow what is to come after Wano. For example, in a recent chapter of the manga, it was revealed that the character of Vegapunk, a brilliant scientist who works for the World Government, has developed a new technology that allows people to transfer their consciousness into inanimate objects. This has led fans to speculate that the series may explore the implications of this new technology in future arcs.
Another hint that has been dropped in the series is the existence of the “One Piece,” the treasure that the main character, Monkey D. Luffy, is searching for. While the true nature and location of the One Piece are still unknown, it is likely that the series will eventually explore this plotline in more depth, potentially after the Wano arc concludes.
There have also been rumors and speculations about potential arcs that could come after Wano. One of the most popular theories among fans is that the series will explore the “Elbaf” arc, which would focus on the giants of the One Piece world and their island home, Elbaf. This theory is based on various hints and clues dropped throughout the series, including the fact that several important characters have ties to the giants.
Overall, while it is impossible to say for certain which arc comes after Wano at this point in time, there are several hints and clues that suggest where the series may be heading next. Fans will have to wait and see what Eiichiro Oda has in store for the world of One Piece after the conclusion of the Wano arc.
