Everything was destroyed, not only Konoha, but everything is take over by such a unstoppable darkness take over a world.

The only survive was Haruno Sakura and Hokage Tsunade.

16 years old, short pink-hair, emerald glow green eyes and that are Haruno Sakura, right now sitting in a secret hideout waiting for Tsunade.

BAM!

Sakura look at the door and saw Tsuande panting, and run toward Sakura as Sakura give her a water bottle. Tsunade took and drank all the water. Then she look at Sakura, "Sakura, I'm giving you a new mission." Tsunade said as Sakura shock, she couldn't believe Tsunade would give her a mission in a time like this.

"Wha-"It an F-ranks mission!" Tsunade said interrupted Sakura, Sakura put confusion face, "What's a F-ranks?" Sakura said as Tsunade sighed.

"F-ranks mean Forbidden Mission, this rank is very very dangerous and never ever coming back where you belong, this ranks is only a kage level or higher." Tsunade said while Sakura blink a few times. "I don't understand this, but why me, I'm just a Chinen and a medic nin and-"DAMN IT SAKURA! YOU DEFEATED OROCHIMARU! YOU BRING SASUKE BACK IN THE VILLAGE! YOU KILLED ALL THE MEMBER OF AKATSUKIS! AND YOU SURVIVE THIS ENTIRE DARKNESS WORLD! And you are perfect for this mission." Tsunade said while Sakura look at her with jaw open and wide eyes.

"O-okay, then what this mission about?" Sakura said

"Your mission is going to another world, and then you are going to protect Sora, Kairi and Riku. Never tell anyone about this. And no matter what Sakura, you need to protect them, never let them out of your sight, do you understand; protect them when it comes to danger okay? Never ever forget this mission." Tsunade said as Sakura nodded her head.

Tsunade sighed, while Sakura look down.

"When will I leave?" Sakura said then she looks up as Tsunade frown.

"Right now, we don't have enough time!" Tsunade said as she stands up.

"But, what about you? What about everyone? And Naruto?" Sakura said standing up.

"Don't worry Sakura, when you go another world. Everything will go back where these the way are. Okay?" Tsunade said put her hand on Sakura shoulder as Sakura smile and nodded while Tsunade sad smile.

"I love you Sakura, you're like a daughter to me." Tsunade said then kiss Sakura forehead.

Tsunade step away from Sakura and cast a jutsu.

"I love you too...Okaa-chan." Sakura said as Tsunade eyes wide then close eyes while smile.

"Forbidden Worlds no Jutsu!"

Then everything went black.
