Tsunade was winning alot of money in the casino she was at. She had a bad feeling because she was winning so much so she left. The next day she ran into Orochimaru preparing to make a deal. He would give back Tsunades brother and her lover if she fixed his arms. Tsunade was considering on wht she would do. But Shizune was beging her not to take the deal because her brother and Shizunes uncle would like it. Then Tsunade poisened Jiria when they had dinner. The next day Tsunade went to meet Orochimaru and she refused.

After Naruto and Jiraiya found Tsunade they all had dinner together and Jiraiya asked Tsunade if she would be the next Hokage because her Grandfather was the first and the founder of the leaf village. Naruto went crazy saying that he was supposed to be the next hokage. Jiraiya told him that he still had a long way to go and the village needed a new leader. Tsunade politely refused. Then she asked why would anyone want to give their life for someone else. Naruto yelled at her and Tsunade challenged him to a fight.

The Fight

When her and Naruto were both outside Tsunade lifted one finger and said this is all I need. After she said that Jiria told her not to show off. When Tsunade said come and get me Naruto pulled out a kunie and ran towrds her. When he came arms leangh she plucked him. This pluck took off his headband and knocked the kunie out of his hand. He went flying into the air and when he landed his headband and kunie landed right beside him. He was stunned by her streaghth for a second but when he recoved he got back up. When he got back up he tried to do Rasengan on her. Tsunade was suprised that Naruto was trying the fouth hokages jutsu. Naruto failed to finish the jutsu and Tsunade looked like she was no longer surprised but mad. She started to yell at Jiria and ask why he taught him the Rasengan when he knew that only he and the fourth could complete that jutsu.

The bet

After Tsunade said that Naruto could not do the Rasengan he told her he could perfect in a week. Tsunade took this as a bet and she said ok whats in it for me. Naruto said "If I can't perfect the Rasengan in a week than we wont't bug you anymore about why your not going to be hokage. If I can perfect the Rasengan in a week than I want that Necklace you have around your neck.

The Necklace of Death

When Naruto said this Tsunades eyes went wide and she remembered the first time she gave the necklace to someone. The first person she gave the necklace to was Shizunes uncle. Tsunade loved Shizunes uncle and when she ave him the necklace was the day before he went to war. That night, he died in battle. Tsunade was grief stricken. The second time she gave the necklace to someone it would be her little brother as a birthday gift. The day he also went to battle even though Tsunade told him not to and that it was to dangerous. The next day I was dead. The paramedics told her his body was so twisted up that you couldent even tell who it was.

The truth is, is that Tsunade is actually as old as Jiria but she uses her chakra to help herself look younger. One of her main fears is growing old.

Orochimaru's Deal

Nearing the end of the bet Orochimaru along with Kabuto to secretly make a deal. The deal is that if Tsunade heals his sealed arms he will bring back her brother and boyfriend.

Sasuke Retrieval

One day Sakura reports that Sasuke has left the village for Orochimaru. Tsunade tells Shikamaru to make a team but the team must have Naruto in it. Shikamaru then gathers his team which consist of himself, Naruto, Neji, Choji, Kiba and Akamaru.

Whle that is going on Tsunade studies the human body in order to figure out how to heal Rock Lee's body.

Abilities

Using precise chakra control, Tsunade is able to focus chakra into her fist and feet and release it when she punches or kicks that gives her massive strength, enough to split the ground in two with just her finger.

There is diamond-shaped mark on Tsunade's head which is part of a hidden seal that covers some of her body, she uses this "Secret Mark Seal" to store chakra in and is able to use that chakra when needed. She'll use this in junction with "Creation Rebirth," a technique which speeds up cellular creation and regeneration to heal her body, rendering her almost immortal on the battlefield. But this happens at a cost though since this shortens her life span each time she uses it. She also has an electrical technique called "Important Body Points Disturbance." With this technique she sends an electrical current through her opponent's body by touching them. This doesn't physically harm the opponent, however the brain and body coordinates it's motor functions through electrical pulses, thus Tsunade's technique disrupts those pulses causing the opponent's body to react differently than they want it to.

Being a medical specialist, Tsunade's able to use techniques such as: "Mystical Hand" where she focuses chakra in her hand that speeds up the healing process of wounds, for herself or others. "Chakra Scalpel" where she focuses chakra around her hand which acts as a blade. Since it's composed of energy, it is completely sterile. And "Poison Extraction" where she uses her chakra to remove poison from one's body. She also is strong enough to use the Forbidden Medical Ninjutsu: "Total Life Sacrifice": where she gives the other person undergoing this, their chakra, total strength, and life force. She is one of the most powerful Kunoichi, and one of the most powerful Medic-Nins in the Naruto universe.

Tsunade also continually uses a transformation jutsu to keep her looking young. She is also capable of summoning giant slugs which are capable of spitting acid.
