Bleach, one of the big three anime (along side One Piece and Naruto). We all know they had its anime series cancelled at the end of 2012 with little explanation as to why.
The mange however was to continue strongly. The manga began in August 2001. It continued until the same month of 2016 in the weekly magazine Shonen Jump.
But with the manga continuing, why did the anime stop in the first place? Well we simply do not know. All we do know is that the last episode we got to see was number 366 and then it was just cancelled.
