So, Madara-san, i just went over the last episodes of the last arc, they are fully cannon! And ofcourse i got excited like i was 13 lol bleach is a great show, the animation progresses and becomes more stable through the progress of the show, you can skip fillers they are not really important... although, my husband felt like Blaech should have ended in season 14 anime, the next season leaves you wating for more, after 15 seasons you can just continue the manga from chapter 480 is the last manga arc. Either way, if you choose to watch or read, or both i hope you enjoy it as much as i did (*.*)
