Yotsuba&! is the story of a young girl as she experiences the world in the budding years of childhood. Once she gets into school, that experience becomes structure, codification, and learning because you’re told (and only what you’re told) rather than the magic of a child discovering something on her own.
How old is Ena? Yotsuba’s 5 (so we’ll see her 6th birthday in a future chapter, I’m sure); are they close enough that they’d go to the same school, even for a bit?
Take into account just how long it has taken him to get this far and how many more months there are before school starts, I figure that it will almost have to end then.
Oh, and with Azumanga ending on the last day of school, it seems only fitting that Yotsuba&! end on the first day.
Once it’s over, I’d be game to see an extended epilogue of Yotsuba in high school, but he’d have to write it extremely well for it to fit.
