A long anime series of 24-26 episodes will typically change gears halfway through with brand new theme songs, a new story arc and a fresh set of characters. But this spring’s crop sees five titles buck this trend, in a move that has surprised the industry. Cyzo News reports that “Fate/Zero,” “Medaka Box,” “Kimi to Boku 2,” “Jormungand” and “Hirono no Kaera” all have lengthened story arcs and will be keeping the same theme tune throughout the season. This effectively slims down the merchandising package for the season. Sales of DVDs, singles and figurines make up a significant part of the earnings for anime shows, and the move is seen as a reflection of economic hard times in otaku industries.
