^ Yeah, it is unfortunate how the K12 have been pushed into the background. They were major players in Part 1. But now the story is mostly about Naruto, the larger world around him, and the Uchiha. Outside of Shikamaru, and one rare instance with Hinata, most of Naruto's friends do not matter.
The anime though feels the K12 are important stars and always tries to keep them involved with filler.
