The Crunchyroll main page for their 2010 Winter series Omamori Himari now has a new message on it that may be a surprise for fans. "All videos will be removed by Kadokawa thirty days after the release of the final episode." It appears that Kadokawa is employing a recent new plan for shows the license out to streaming in that their windows for viewing on sites like Crunchyroll and their YouTube channel are not forever (only torrents are forever, apparently). It was recently discovered that the show Sora no Otoshimono was pulled from Crunchyroll though no notice was given about it. This ties in with how new episodes of Fairy Tail are only available for that period of time as well, which is why we haven't gone back to the beginning to review it or tried to catch new episodes. With this happening to several Kadokawa shows, it points to an overall plan rather than the idea that a show may be licensed by someone.
While we believe that limited runs are a good thing overall as it encourages people to watch the shows in a timely fashion, a thirty day window is definitely short and both Kadokawa and its partners (Crunchyroll and others) should make due diligence in informing fans of when these windows will operate so as to not surprise potential viewers later on when they go back to catch up on something or investigate it based on a recommendation from a friend. It's not expected for a partner like Crunchyroll to have a lifetime or DVD style lock on a show for seven years or something, but having a new winter season show disappear so soon after its final episode may drive people to avoid Kadokawa shows in the future if they aren't able to keep up on it.
