Given I believe that box was the Nagano apples given to her by the family in chapter 2 that were in the house that used to be where her grandfather's friend lived, I wonder what Kumakichi is doing flying away with them like that.
Unless the apple trees predated the family - and are themselves somehow magical or otherwise "magically significant", which is why Kumakichi flew away (??) with them.
Hopefully we get more on that sooner than later.
But in the meantime, thanks for the TL work as always.
