The long ones all seem to start as light novel titles, so there’s something about current Japanese light novels that results in their titles being ridiculously long. (Older ones like “Kyo Kara Maoh!”, “Twelve Kingdoms”, and “Crest of the Stars” don’t seem to share the issue—the earliest really bad one I can remember is “What will you do at the end of the world? Are you busy? Can you save us?” or whatever it was called.)
