The Six-Tails Unleashed (六尾発動, Rokubi Hatsudō) is an arc of the Naruto: Shippūden anime. It covers episodes 144 to 151. It deals with the bond between masters and students named Utakata, the jinchūriki of Six-Tails, and his student Hotaru. This arc is preceded by the Fated Battle Between Brothers and followed by Pain's Assault.


When Hotaru and her guardian, Tonbee, are being attacked at their mountaintop fort, she and Utakata escape with En no Gyōja's secret kinjutsu, while Tonbee tries to hold off the attackers, but was easily defeated, and the attackers, the Magaki Group, go after them. Team Yamato are assigned by Tsunade to go and protect Hotaru on her way to the Tsuchigumo village. When the team find the fort, they saw Tonbee, who has been viciously attacked by the four-man bandits. Sakura stays and heals Tonbee, while Naruto, Sai, and Yamato follow Utakata and Hotaru. Naruto catches up to Utakata and Hotaru, and Utakata attacks Naruto with some of his Soap Bubble Ninjutsu. After Utakata learned that they are not attackers, he entrusts the protection of Hotaru to them.

Utakata's past is explained, including a vision of his master attempting to draw out his tailed beast. Hotaru refuses to let the Konoha ninja escort her to the Tsuchigumo clan's secret village. Sai then tricks her into thinking that giant leeches are falling on her and she begs Naruto for protection. When they reach the hidden village, Naruto leaves the village with a suspicious feeling because of the way that the villagers looked at Hotaru. Utakata also starts fighting the Magaki Group, and starts to gain the upper hand easily, but then they trap him in a Lightning Release barrier that implodes.

Hotaru's uncle betrays her to the Magaki Group, but when they think that they have found the hidden scroll, it turns out to be a bomb. Hotaru escapes, and she meets up with Utakata in the forest. He faces off against the bandits again, and quickly flees. After Utakata escaped with Hotaru, the bandits were confronted by their leader, Shiranami. He showed them that Utakata was a missing-nin from Kirigakure with a bounty of 50 million ryō. Akaboshi asked their leader what they should do, which he began to muse about. When Hotaru and Utakata were alone, Utakata was about to leave Hotaru again, but Hotaru, trying to convince him not to leave her alone, partially took off her shirt, showing him something on her back that shocked him.

All of a sudden, the Kirigakure Anbu found Utakata and wrapped him up with their Water Release: Water Whip technique and began subduing him with their Lightning Release: Electromagnetic Murder. The captain revealed to Hotaru, who he was holding hostage, that Utakata was in their Bingo Book, and was wanted for killing his master. Naruto and his team arrived and managed to loosen one of the water whips holding Utakata. Both parties began to fight, but the leader of the Kirigakure Anbu appeared, and discussed the situation with Yamato. Due to Hotaru's insistence to be with Utakata, it was agreed that Utakata stayed with Team Yamato and they wouldn't hunt him until she was safe, but afterwards, they'd resume tracking Utakata down. Tsurugi, the leader, asked Utakata to return to Kirigakure, saying that the village changed, no longer earning the nickname of Village of the Bloody Mist. Utakata refuses, and says that he will keep doing as he pleases.

After the groups part ways, Hotaru begins hurting from an injury sustained during the earlier altercation. Utakata has Naruto collect medicinal herbs. When Naruto returns, he witnesses what was done to Hotaru's back, where her clan's kinjutsu was put. Utakata voices his absolute disdain for people who selfishly take advantage of people's loyalty, only to treat them as tools.

Everyone is shocked to learn that Hotaru actually requested for the technique to be sealed in her. After she explained that she wanted her grandfather's dream to restore their clan's glory to come true. When Tonbee voiced his sorrow that by now the clan had probably lost too much strength to ever return to such a status he suggested they end the potential danger of the kinjutsu by destroying it. Utakata was surprised that Hotaru's grandfather had created a way to safely remove it from Hotaru's body. When Tonbee insisted that no true master would do such horrific things without a way to undo them, Utakata wondered if the same was true for his master. Utakata resolved to find Tsurugi again to learn some answers about his late master.

Hotaru initially refused the idea to destroy the kinjutsu, feeling that it would make all her grandfather's efforts for nothing, but Utakata made her see that she couldn't restore their clan with such a destructive technique. While willing to accept this decision as a final act, she offered one other possible solution, to search for a man named Shiranami, who is an immensely gifted ninja who studied En no Gyōja's teachings and could be of great help. It was then decided that Naruto would attempt to find the man in two days while preparations for removing the kinjutsu were made.

When Naruto Uzumaki sought out Shiranami, the Magaki leader, who believed the latter was an ally, the Magaki Group ambushed Naruto and used Infinite Embrace to drain his chakra. While Chūshin beat Naruto, Benten almost revealed their plan before Akaboshi silenced him. Angered at being deceived, Naruto unleashed the Nine-Tails' chakra and broke out of the Infinite Embrace. Though shocked at Naruto's strength, the Magaki used their Multiple Infinite Embraces to crush Naruto. Much to their shock, however, Naruto was still able to resist, but not for long.

Later to Hotaru's dismay, Utakata suddenly leaves. Not wanting him to leave her, Hotaru goes off to find him. Along the way, she runs into Shiranami himself. He sympathises with Hotaru's loneliness and desire to restore their clan. After being convinced not to destroy the technique, she decides to write a message to Utakata. However, Shiranami reveals his true colours and knocks out Hotaru, taking her back to the Tsuchigumo village.

When Utakata is unable to find Tsurugi he finds Hotaru's messenger bird with a note for him. While it is from Hotaru saying she found Shiranami, Utakata is still at unease, feeling something is wrong. He goes to the location Hotaru wrote and finds that Shiranami is actually the leader of the bandits who trapped Naruto in a fūinjutsu. Utakata then uses his tailed beast chakra to scare the bandits and make them run.

Utakata defeated by Pain.

Afterwards, he and Naruto track Shiranami back to Hotaru's village, where it is discovered that Shiranami took control of the villagers with his technique. The villagers attacked Utakata and Naruto and they were also confronted by the Magaki Group. Just before things got worse, the rest of Team Yamato arrived while hunting for Hotaru. Yamato, Sai and Sakura were fighting the villagers and the Magaki Group, while Naruto and Utakata were trying to save Hotaru from Shiranami. In the end Naruto and Utakata manage to save Hotaru and Team Yamato parts ways with Hotaru and Utakata. Hotaru and Utakata decide to leave Hotaru's village and travel around while Utakata trained Hotaru to make her stronger. Before they begin Utakata decides that he wants to confront the Kirigakure Anbu unit and tells Hotaru to stay behind. He attempts to make contact but is unable to do so. He soon discovers the mask of one of the Anbu units that was left behind. After discovering the mask he reaches the conclusion that the Kiri Anbu were killed and Utakata is confronted by Akatsuki member Pain who appears to be the one behind the attack. Pain tells him he is here to capture the Six-Tails. Utakata puts up a fight, but in the end is captured by Akatsuki.

  • Usually, video games don't include filler or filler arcs into their storylines, however in Naruto Shippūden: Ultimate Ninja Storm 3, when Naruto Uzumaki meets the deceased jinchūriki and their tailed beasts, Utakata reflects on meeting Naruto prior, directly referencing the arc, where the two jinchūriki had previously met. This only happens in the English version however, as the Japanese audio makes no mention of a prior meeting.
  • In episode #324 of the Naruto: Shippūden anime, some of the events from this arc are recapped, including an extension of Utakata's capture by Pain. This marks the first time the anime largely focuses on a past filler arc.
  • Despite the title, Saiken is featured very little in this arc, only appearing at the very end.
