...there is a short film...
That was news to me, so I asked AI for some details. For everyone also interested in it: the title is "Mei to Koneko Basu" ("Mei and the Kittenbus") and it is a 13 minute film displayed (officially) exclusively for visitors of Ghibli Museum in Mitaka (part of Tokyo).
Here is IMDB link.
RE: Magic and pain embrace each other, these are my favorite Ghibli films.
