Silence… fires spreading about… alarms in konoha going off… ninjas rushing to defend their home against the mighty Kyubbi. These were the thoughts that went through the Yondaime Hokage's mind as he prepared for battle. He gathered his things and his daughter. Newly born and taken from his wife, Kushina Uzumaki, Natumui was about to experience a night that she would never forget.
Hokage's Office
"You ready Minato?" asked the Yondaime's sensei, Jiraiya, as he stood in the door way.
"Almost sensei. I just need to release all my chakra seals so that I'll be able to perform the Shiki Fuuin."
What Minato didn't see was the Sandaime Hokage, Hiruzen Sarutobi, sneak up behind him and deliver a devastating chop to his neck.
"Sorry Minato, but you have a life ahead of you. In addition your daughter will need you more than ever now that Kyubbi will be sealed into your daughter," spoke Sarutobi as he caught a falling Minato. With those words he took baby Natsmui and whisked her to the battle of the Kyubbi.

"Summoning Jutsu!" was heard with a puff smoke following close behind it. Out of the smoke came the summons of the Sandaime Hokage and his student Jiraiya of the Sannin.
"Why have you summoned me hear you little bra?t" a mad Gamabunta ground out with a puff of smoke coming out of his nostrils.
"I concur with 'Bunta. Sarutobi why are we facing one of the Nine demons of hell?"
"I am sorry 'Bunta, but we need your help so that we can seal the Kyubbi away into Natsmui. To do that however, Sarutobi will be sacrificing all of his life force to do it," replied a terrified Jiraiya as he had no wish to go against 'Bunta.
"Very well we shall help you with this task. But Jiraiya make sure that Natsumui becomes my summoner."
"I too will help," stated Ennma the Monkey King, "but I want Naruto, the oldest to be my summoner. I'm gonna need someone new with Sarutobi deciding to go out of the business."
"Get ready guys, here he comes!" With a roar the great Kyubbi re-started its rampage. However, fortunately for Konoha the Kyubbi was held down by Ennma and 'Bunta. Meanwhile Sarutobi performed the Shiki Fuuin. With his last breath he told Jiraiya that he wanted Minato and Kushina to treat Naruto the same as they would treat Natsmui.
"Hai sensei. I will make sure to give this message to Minato. He will treat Naruto the same as they treat Natsmui."
Hokage's Office
"Damn you Jiraiya-Sensei. I was supposed to make the sacrifice." Minato yelled in frustration when Jiraiya came back to tell him that the Sandaime Hokage had made the sacrifice instead.
'Well this is as good a time as any.' Minato thought as he took Natsmui to the crowds of Konoha with Kushina at his side.
"People of Konoha, I give you my daughter savior of this village from the foul entity known as the Kyubbi!" Cheers erupted from the people of Konoha. Shouts of Yondaime and Natsmui echoed from below.
Unknown to Minato and Kushina, a rift in time opened up fight above Naruto's crib. Suddenly, a black dragon-like chakra entity escaped from the hole and sealed itself in Naruto making him the Jinchurikki of the Jubbi. Elsewhere in heaven, Kami was bestowing the powers of the Zanpakto upon Naruto. He would grow up to become the best shinobi Konoha has ever seen. He would be even better that his father and sister. This is the story of the Electric Dragon of Konoha.
