Where is the end of the world?
Though it varies from person to person, children always have all kinds of whimsical ideas and are curious about everything.
Why does the sky turn dark, why is the sea blue...
So it's not unusual for a child to wonder if the world they live in has an end, and if so, where it is.
Some children will ask their parents or teachers, and mostly they will get an ambiguous answer.
While those with more drive will seek the truth in their own way.
For example, clumsily writing down their wishes and then putting the letter into a bottle, ceremoniously casting it into the sea, hoping it will bring a distant reply.
——"If you are at the end of the world, please tell me where you are."
The message inside that drifting bottle picked up by the Hero, with its crooked handwriting, is most likely something like this.
One would know that such actions are pointless, once they've matured a bit, as even the question itself has no logic.
