Watch Naruto Shippuden 221 before you read this synopsis.
In the last episode of Naruto Shippuden 220 Naruto has been asked to unlock the Nine Tails within him. Naruto is asked to press the Storing Square. This would open the Tetragram Seal. It is of course easier said than done. The Nine Tails gets its power by merging its chakra with its will. To control this power Naruto must isolate the Nine Tails' chakra, make his own chakra and turn it into his power. By drawing out Nine Tails chakra Naruto will draw out also its will. This must be done with utmost care as Nine Tails is a mass of hatred tightly wound into a chakra. Nine Tailes will always look for hatred within Naruto to try to overtake him. It will be up to Naruto to draw out both chakra and will from Nine Tails and separate them by his own will. This is the only way to control the Tailed Fox. Losing this control would mean that Nine Tails would be completely resurrected.
Fourth Hokage made this Tetragram Nine Tails Seal by using Eight Trigram Sealing Formula to allow a small bit of chakra to leak out and become part of Naruto. Over time though, Tetragram Seal was weakening and Jiraiya was very concerned that Naruto would turn into Nine Tails. That is why a key was created to tighten the Seal. One day Jiraiya summoned Gerotora to ask him to loosen the seal just a little bit. This should teach Naruto to resist Nine Tails' will.
Jiraiya then taught Naruto how to control that Tailed Fox. Naruto got frustrated, but Pervy Sage used old fashioned reversed psychology, telling him that he couldn't possibly match up to his father. That fourth Hokage developed such extraordinary jutsu that no one, not even Pervy Sage could master it. But there is one shinoby, who has a potential to master such jutsu and that is Naruto. He is shinobi who inherited the Rasengan. Nine Tails chakra is inside Naruto and only Naruto can control it. This is the legacy that Fourth Hokage left for his son. When Naruto heard the Fourth Hokage Legacy he decided he wanted to undergo the training to master his own chakra control. First attempt at controlling this beast didn't go very well and Jiraiya got hurt.
Naruto remembers when he fought Orochimaru he relinquished his will to Nine Tails power. Hearing about Sasuke made him angry and Nine Tails used that to take control over Naruto. Jiraiya and Sakura were saved by Yamato who used his wooden jutsu to restrain Jinchuriki by boxing him in.
Contract was completed by Naruto touching the key and Gerotora the Seal Guard jumped up to Naruto's mouth. This is where the storage is. Inside Naruto. Storage complete.
Kabuto Yakushi is carrying on Orochimaru's will by going after Hidden Leaf and Akatsuki. He introduces himself to Madara. Using the Reanimation jutsu, the forbidden jutsu, known only to Second Hokage and Lord Orochimaru, Kabuto presented Itachi, Sasori, Deidara, Kakuzu and Nagato. He would revive them to help the cause.
Kabuto pretended to want nothing, but Sasuke in exchange for his reanimation services and great military might. Claiming that he only wants the pure truth behind ninjutsu. Tobi finally agreed to handing over Sasuke, but only once the victory in the 4th Great Ninja war was secured. Kabuto, to prove he is serious about having his demands met, opened another coffin. We can't see who is inside, but whoever it is, shook Madara up to his core. It seems that Madara and Kabuto will join the forces to start the Fourth Great Ninja War.
Suggestions are being made that Naruto and Killer Bee should be hidden for protection. If captured, Ten-Tailed Beast could be formed of all Tails and that would be disastrous. Let's see what the "Five Kage's Decision" will be in next episode of Naruto Shippuden 222 right here at TailedFox.
