"Hanabi's Decision" (ハナビの決意, Hanabi no Ketsui) is episode 390 of the Naruto: Shippūden anime.
As Hanabi continues her training with her father, she thinks to herself that she is destined to be stronger than her sister. She is later informed by Natsu that Hinata will be participating in the Chūnin Exams but notes that it is a waste of time. When Natsu tells her that Hinata is heavily injured after fighting Neji, she rushes to the Konoha Hospital. Asking why she didn't withdraw, Hinata responds that she is not willing to give up and says that not going back on her word is her nindō. Hanabi later attends the finals with her father to witness the battle between Naruto and Neji. She is later seen training to use the Eight Trigrams Palms Revolving Heaven under her father's supervision but fails to master it. When Hanabi watches Hinata train with Neji, she wonders why she is so confident despite being deemed a failure by her father. Later upon returning to the village from a trip, Hanabi and her father are informed of the Akatsuki's assault on Konohagakure and immediately rushes to the scene. Arriving at the village, they are shocked to learn that Hinata battled against Pain on her own. Upon realising Hinata's confidence and that she never gave up, Hanabi begins to admire her sister once more and is eager to train with her father to grow stronger herself.
