Kakashi’s Anbu History – Naruto
Naruto is arguably one of the biggest filler offenders in all of anime, with what seems like more than half the show’s arc having no real effect on the main plot. However, there are definitely some diamonds hiding in the rough, especially when it comes to Kakashi Hatake’s time in the Anbu Black Ops.
This arc has almost everything you could ever hope for from filler. It delves more into Kakashi’s life and backstory –explaining why he’s a bit on the odder side of things – and even features younger versions of other prominent characters from the main story like Itachi, Yamato, Hiruzen, Orochimaru, and Shisui.
It is honestly hard to even call this filler. Not only does it contribute to the plot and add depth to characters that are integral to it, but it is also a fascinating and enthralling story.
