I don't get it; wouldn't another of Palette's games, もしも明日が晴れならば (or "If the weather holds fair tomorrow", or "Moshiraba") be better for dramatic potential? Every loves a good tear-jerker as Key's works proved, and after the failure of recent shows like Hoshizora, wouldn't a change back towards tragedy prove more popular with fans?

Mashiro-Iro Symphony doesn't look like the best of games in Palette's catalogue to make an anime, sadly.
