"So you are taking a mission in which I have not given you?" a blonde haired woman asked.
"Hai."
"Why?"
"Because, this mission cannot be given like the others."
The woman grinned.
"Alright. If there is any missions that involve going there than I will notify you at once."
"Thank you Hokage-sama."
"Sakura, take care. Don't forget to write."
"I won't. Maybe you guys can take a field trip and come visit. Just make sure you tell them the rules first."
"Byeblossom, I'm gonna miss you." Tsunade hugged her daughter-like-figure.
"Bye. Thanks for taking care of me. "
Sakura ran out of the fifth Hokage's office and ran towards her house. Upon entering she placed a genjutsu so that her house disappeared form sight.
Upstairs in her attic Sakura looked at the village she grew up in. She was going to miss this place, but she really missed her real home.
Doing a series of handsigns she called out, Haruno Family Secret Jutsu: Dimension Travel!"
A shower of petals and snowflakes encased the thirteen year old and disappeared, leaving nothing in its wake.
Once Sakura woke she noticed she was in a living room of some sort.
"Welcome back stranger."
"Obaa-san, its good to be back."
"Yes, it has been a while..Ryuzaki Sakura."
