Naruto's Twin sister Hina

It was the worst night ever.

"Wa….. Wa..."

It was the cry of a baby. In fact it is not one but two. A boy and a girl.

"Kushina, don't worry. Leave everything to me. I will take care of it"

With that Yellow flash (Minato) disappeared from the room.

...............….

Minato appeared on the statues of the faces of Hokage. He looked at the Kyuubi (Nine Tailed Fox) that was destroying the leaf village.

Minato aura was like something it can't be ignored. Of course kyuubi turned it's attention towards the Minato in the order of the Masked man that was controlling the beast.

Kyuubi released a large Beast Bomb towards Minato. The speed of the bomb was like even the speed of the sound will lose to it. Minato quickly made hand signatures and created a large black hole with a seal on it.

The blackhole swallowed the Beast bomb in it and disappeared. At this moment Minato was like a badass character that can beat anyone.

The Beast Bomb was teleported to another place. All they hear was sound of the Bomb. With the bomb teleportation every one in the Leaf Village understood that it was Minato's doing.

While Minato was focusing on the Kyuubi suddenly a attack was launched from behind. It was the Masked man who was calling himself Uchiha Madara. The name that can make everyone fear.

Minato dodged the attack and he launched the attack on him with the Marked Kunai. But his hand went through the body of the masked man. It was like he was hologram.

The masked man grabbed the hand of Minato "From now on you are my opponent not Kyuubi" With that they were teleported to the another place.

..................

Minato was shocked. He don't know what kind of jutsu it is. One thing was sure the man in front of him is dangerous. In order to seal the kyuubi he needed to release it from the genjutsu first. Inorder to do it he needed to defeat the masked man.

Minato tried to attack the masked man. Again he literally went through his body like a Hologram. Minato was confused a moment.

Minato closed his eyes a second and calm down.

"Let's Do it"

With that Minato threw the marked kunai aiming the forehead of the masked man and ran towards him but again it went through his head like a hologram.

When the Masked man was about to grab the Minato he felt like he won but Minato teleported to the marked kunai that just passed through his head and hit him with the rasengan.

It all happened within the fraction of second. No one would have expected Minato to teleport him to the kunai that just passed through his head the previous second.

Minato didn't give time to the masked man and teleported to the marking on his back shoulder and placed the seal on him. The marking on his back shoulder was placed with the attack of Rasengan. Attacking and placing the mark on the enemy at the same time. That's why he is one of the badass character.

With the seal is placed now kyuubi is no longer in the control of the masked man. That doesn't mean it stop it's rampage.

Minato teleported himself, Kyuubi, Kushina and the twins away from the village. With the Kushina jutsu they chained the kyuubi.

"Kushina I'm sorry"

"SHIKI FUUJIN"

With that he sealed one half of the Kyuubi within himself. Then he placed the twin boy on the ritual to seal the other half of the kyuubi inside him. Minato didn't want to do it as a father but as a Hokage he needed to do it to maintain peace and to defeat the masked man in the future with the help of the power of kyuubi.

Minato didn't have the heart to seal inside the other baby and the reason is she is a girl. He know's how Kushina suffered due to the sealing. He didn't want his baby princess to suffer.

At that moment Kushina body was very weak. She lost the control of the chained jutsu for a moment. Kyuubi tried to attack the baby in the ritual but Minato and Kushina got in between to save their baby.

Kyuubi's long claws pierced through their chest. Even in that state Minato summoned the mountain frog and handed over the key to the seal.

They didn't have much time to live. Kushina didn't want to let her babies live alone in this world. She wanted to live happily along with them.

"Don't be picky about food. Eat more food and grow tall"

"Don't stay up late everyday"

"Make friends"

"Don't fight among yourself"

"don't drink alcohol until you're 20"

"Don't forget about the three voices of Shinobi"

"Save money"

"Make sure you are happy with the person you are going to marry"

These are the last words of kushina to their babies. The remaining half of the kyuubi was sealed inside the twin boy.

With that Minato and Kushina died. The other shinobies arrived too late. All they hear was the cry of the two babies.
