The names of these series have to be taking the piss. Each one is more bombastic, yet more forgetful, than the last.
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.)
I’ve always read that it’s because many light novels started online, and the way they were listed meant you needed the title to really grab folk’s attention.
(I actually really like this particular anime; the animation is often iffy but art and story really appeal to me!)
