These list are based on the most selling blu ray on our otaku shop marketplace. So, the result maybe differs from another anime sites out there. And please note that this list not also based on the blu-ray released, but based on when anime was aired on television. So, indirectly you will see the list of the best anime in 2012 that we have divided into two seasons, summer and fall.
You’re right, for 2012 we only have two seasons because of gathering project database for Anime Bibly started since summer 2012. Therefore, we do not have official data before the spring 2012. However, we will still provide excellent results.
