Man, this anime is an absolute joke. I click on an episode for the first time in months hoping to see some interesting story progression, and I'm met with another utterly pointless filler that any 7/10 rated slice-of-life show could outdo. How is it possible for a series to go through 106 episodes (more than four times the length of any regular mid-length series) and have almost nothing of consequence happen. Seriously pathetic.
Actually this arc is canon, not filler. Tho not in manga, it was a light novel written by Kishimoto Masashi. If done by the creator and still part of the same universe, like Boruto and Naruto, unless otherwise specified its then considered canon even if under different media format, such as Dragonball Super: Broly is Movie but never turned TV Series like other 2 DBS movies yet is still Canon
