The docks of West Outer Heaven are mostly dominated by Kyushu merchants, as well as a number of sailors from Kyushu and Fengyu. These people have nothing to do with the aristocratic families of Kyushu, especially the merchants, who, despite being under control, hold a strong disdain for the aristocracy.
Miss Zisu and her party, cloaked in long robes and hoods, hurriedly boarded a ship at the dock, arranged by these Kyushu merchants. Even though the sailors were curious, no one dared to initiate contact with these people.
That's because, before their arrival, the sailors had already been repeatedly warned not to meddle in others' affairs. So, facing these individuals, the sailors maintained a united front of silence.
