Beyond Konoha - Different Dimensions

Imagine Kushina and Minato were still alive, but somehow, in another dimension...
What if Naruto wasn't Minato and Kushina's only child?
What if Naruto had a little sister?

Meet Kasumi-Akane Uzumaki Namikaze. Quite a mouthful huh? Follow Kasumi as she's whisked into Naruto's world thanks to a certain masked man... How will Naruto and the others react? And what about the raven haired Uchiha who has his Sharingan eye on her?
