Quick recap
Filler arc. Naruto, Sakura, Sai, and Yamato meet Hotaru, a girl who carries her clan's forbidden technique inside her body, and Utakata, a Mist rogue she wants as her teacher. Utakata is the Six-Tails jinchūriki and wants nothing to do with students. Bandits led by Shiranami hunt Hotaru, and in the end Shiranami turns out to be the real villain: he wants to use her body to gather natural energy and unleash the technique. Naruto and Utakata face Shiranami, and Utakata uses the Six-Tails' chakra to contain the energy. Once it's over, Pain ambushes Utakata and beats him. With his last strength, he blows soap bubbles telling Hotaru to live on.
