Long time ago in Konoha, the Kyuubi was unleashed and it attacked the village, leaving great devastation amongst the village, buildings were destroyed and some shinobi lost their lives. The fourth hokage saved everyone's lives by sealing the demon inside his own daughter, Minato Namikaze died after sealing Kyuubi into Sakura, and Kushina Uzumaki (Sakura is now an Uzumaki and Naruto is now a Yamanka, he is Ino's twin so he can use mind jutsu and stuff)also passed away. Leaving their daughter orphaned, a tiny pink haired and green and blue eyed girl with a seal on her, the seal that was marked on her from the sealing of Kyuubi, the nine tail demon fox.
