Currently there have been no plans to animate Episode 367 and no new information has been released regarding the continuation of the Anime. The last episode produced is Episode 366. The Manga continues the story after Episode 366, from Chapter 480. The Manga has not ended.
Note: We are not the creators of the anime and nor did we cancel it, nor know why it was cancelled. If there is ever a decision to continue with the latest arc, and it must be official information not rumors, we will update this page further.
The tweet regarding the anime returning in 2014 on April 1st was an April Fools joke.
