Ok! Next chapter time guys :D!
Ok guys, thanks to a review thoughts are now in italics

Flashback:
Suddenly Kabuto gasped. He fell down face-first.
"Nani? Even after I regenerated there is still damage? That jutsu really is something else." he thought, very shocked.
But he wasn't the only one lying on the ground. Naruko was in the same position due to chakra exhaustion and his damage. Tsunade got out of her shocked state (AN: This is due to her fear of blood, that she now managed to overcome) and started to heal the younger blonde.
"Don't die! Don't die!" she screamed, with tears dripping from her eyes. Suddenly she felt something grab her necklace.
"The bet – I won" Naruko said with a weak voice, before fading back into unconsciousness.
End of flashback.
With Jiraiya and Orochimaru (they're fighting on a giant snake right now)

"Who thought something like this would happen. When this kid gets angry things become very troublesome. If I don't kill her now I feel I'll regret the decision!" Orochimaru thought, before jumping down the snake head first, with the Kusanagi in his mouth. Jiraiya jumped after him, but his former teammate grabbed the toad sage's leg before slamming him in the ground. Then he ran toward Naruko and blood splashed in the air.
"Nani?!" Orochimaru thought. He was beginning to hate the amount of surprised this day bringed him.
His blade didn't slice Naruko. Tsunade had protected her fellow blond with her own body.
"Why?" the Snake Sannin asked. "Why do you, a Sannin, protect a mere genin risking your life?"
"Because she is the future Hokage!" Tsunade answered. "From now on, I will also put my life on the line!"
"If you are so eager to die, then so be it!" Orochimaru shouted, with anger in his voice. He then cut Tsunade's throat.
"So, Naruko, it's just you and me left, eh? It's your turn now" he said and slashed his sword at Naruko.

Again Tsunade protected the Kyuubi container. Orochimaru widened his eyes.
"You should be dead already!"
"I said that I'll also risk my life." Tsunade said. Then she lifted her face and you could see strange markings on her face.
"Nani?" Orochimaru was very surprised. "What are those seals?"
"Old friend, you are not the only one that creates jutsu. Thanks to this jutsu I'll never die in battle. Ninpou: Divine Restoration." Tsunade saidand all her wounds started to heal. Orochimaru quickly jumped away to his apprentice
"Kabuto, use the seal on my hand ." the Snake Sannin ordered.
"Kuchiyose no jutsu" Kabuto, Tsunade and Jiraiya shouted at the same time and three giant figures appeared. It was Manda (snake), Gamabunta (toad) and Katsuyu (slug).

The first one to attack was Katsuyu.
"Zesshi Nensan (Sticky Mouth Acid)" she shouted, but Manda managed to dodge the jutsu. Then the snake wrapped himself around Katsuyu. But Gamabunta came to the giant slugs help. He attacked with his sword, but the reptile caught it in his mouth. Meanwhile Katsuyu changed to thousand s of small slugs and reformed herself, away from the snake. The toad backflipped and barely managed to dodge his sword, which Manda throwed at him. It landed just before Katsuyu and Tsunade grabbed it.
"Tsunade, get away!" Jiraiya shouted. "Ready for some oil?"
"Sure thing!" his summon replied.
"Katon: Gamayu Endan" the Toad Sage saidand he breathed fire, while Gamabunta breathed oil. The effect was devastating.
"Did we get him?" the toad asked.
"No, it's just his skin" Jiraiya answered. "GAMABUNTA, BELOW US!"
A second later Manda came out of the ground and wrapped his tail around his enemys body, while he opened his mouth wide. But the snake didn't expect Tsunade coming out of the air and the Slug Princess pierced her enemy's upper and lower jaw with the sword, effectively fastening him to the ground. Stand ing on the weapon, she didn't see Orochimaru's tongue, which wrappened around her neck.
"If you can't die in battle, I'll just strangle you to death" he said.
But he had underestimated Tsunade's strength. She grabbed his tongueand using it she pulled Orochimaru to herself. Then she punched him and turned around, with him flying after in a circle. She jumped to the airand gave her former teammate the beating of his life. Then she stopped for a secondand her hand began to blow with chakra.
"This is the end!" she said, before slamming her teammate with all her force. Orochimaru hit his head on the sword and fell down next to Kabuto.
"Orochimaru, next time we meat prepare to meet the consequences." Manda said and disappeared.
When the smoke faded away everyone was stunned. Orochimaru had stand ed up. He burst into laughter.
"I will definitely destroy Konohaand it would be nice to meat you there, Jiraiya, Tsunade," he said. Then he began sinking in to the ground and you could barely hear his last words: "I am immortal."

Tsunade walked to Naruko. As she watched him she remembered Dan and Nawaki. Soon Jiraiya appeared next to her. Due to her chakra exhaustion she was getting wrinkles all over her body.
"We'll wait until she is fully recovered and then we head for Konoha" Tsunade said. Then she noticed the others looking at her strangely. "This will pass when I replenish my chakra
"Tsunade…" Jiraiya's words were filled with concern.
"There is no Tsunade anymore. You can call me Hokage-sama."

A week later
Jiraiya, Naruko, Tsunade and Shizune were sitting in a restaurant. They were sitting in two comfortable sofas, with the table between them. The ninjas were currently waiting for their food.
"So Tsunade, you have accepted the offer?" Naruko asked.
"Yes. You don't seem happy." Tsunade replied.
"I am just wondering if a person who hides her true body behind a henge, loses all her money on gambling and is addicted to sake can be a good Hokage." Naruko said, not seeing that Tsunade was getting angrier with every word.

"You brat! Come outside with me!" Tsunade shouted.

The slug princess and her fellow blonde were standing on a dirt road. Jiraiya and Shizune were standing next to them. Suddenly Tsunade showed one finger.
"This is all I need to beat you" the slug princess said.
Naruko let out a war cry and ran at Tsunade. He tried to punch her with his right hand, but Tsunade simply dodged. Then the Sannin marked a tap.
"Oh no, this tap again" Naruko thought, closing her eyes.
But Tsunade didn't do what the young blonde expected. Instead she kissed her forehead. Naruko opened her eyes and immediately widened them.
"Be a good woman" Tsunade said with a smile.
"Sure!" Naruko said. She was also smiling.
