One of the main reasons why I liked this filler arc so much is because Kurenai is shown more in depth for the first time in the show. I think it's a great way to start Season 9, and the opening theme is just awesome.
The episode starts with Naruto arriving back at Konoha from training, when he sees a mysterious, quiet girl painting a picture of it. Naruto sees that unlike the current sky, which is blue with thin wisps of clouds, the girl is painting a stormy sky over the Leaf Village. Suddenly, storm clouds gather over the village just like in the girl's painting! Even more startling, she paints a lightning bolt striking the Hokage's mansion in the picture, and the exact same thing then happens to the real mansion! Naruto is shocked by this, and while shinobi put out the fire the lightning caused, Naruto catches up to the girl who left after the lightning struck. The girl is then apprehended by ANBU, who tell Naruto to leave and not mention to anyone what he saw. Meanwhile, Kurenai announces that she is leaving Team 8!
Could there be a possible connection to this mysterious girl, whose name is Yakumo, and Kurenai abandoning her role as Team 8's leader? And if so, what does it all mean? You'll have to watch the episode, and the rest of the arc, to find out!
