So, what purpose did it serve for Oda to bring Aramaki in Wano? Did it move the plot? No. Did it hype the character? No. Did it hint any future conflict? May be Yamato vs. Aramaki? The only thing it did was to hype Shanks, and I doubt it was necessary to do it like this.
3 chapters wasted on nothing that changed anything and the man wants to finish the series in 3 years.
It’s ridiculous how many times Oda writes his way up against a corner, we the fans pull him out, only for him to go back to that corner. When he treats a character that we waited for 8 years to see like this, does he really expect us to be hyped when he brings Imu or Rocks onscreen? Even the 12 years olds he is writing for aren't that stupid.
