From the same 6-movie DVD-box released in China as [Goto ni Naritai](http://www.nyaatorrents.org/?page=view&tid=90868) and [Momoko, Kaeru No Utaga Ki Koeruyo](http://www.nyaatorrents.org/?page=view&tid=96642). Looking for other movies from this box: [Inochi No Chikyuu: Dioxin No Natsu](http://anidb.net/perl-bin/animedb.pl?show=anime&aid=6633) and [Happy Birthday Inochi Kagayaku Toki](http://anidb.net/perl-bin/animedb.pl?show=anime&aid=6632). The last one, [Chikyuu ga Ugoita Hi](http://anidb.net/perl-bin/animedb.pl?show=anime&aid=2532) appears to be fansubbed.
