He did it. He may have not like what he did. But he sealed the Kyuubi into his twin sons. Naruto and Menma. He decided not to use Shiki Fuin instead he used another seal that separated Kyuubi's consciousness and his power.
The soul of the Kyuubi was sealed into his youngest son Naruto, while the Kyuubi's chakra was sealed into his oldest son Menma. Minato decided to seal the Kyuubi's consciousness into Naruto and it's power into Menma. Why? Because he thought Naruto will keep the Kyuubi's consciousness while Menma will use it's power for the good.
Naruto and Menma both had spiky hair. But Menma's hair was exactly like Minato's hair. Except Menma's hair was red like his mothers with blond highlights. His eyes were light blue. But Naruto was a different story. The boy had spiky blonde hair with little red strands. He had purple eyes and three whisker marks on his each cheeks.
We can almost see the whole population of Konoha was looking at the Hokage Tower. On the roof of the building we can see Minato Namikaze the Yellow Flash (Kiiroi Senkoi), Yondaime Hokage of the Konoha and his wife Kushina Uzumaki the Red Death (Akai-Shi), they were holding two little babies one had spiky red hair while other had spiky blonde hair.
"Good citizens and ninjas of Konoha. Yesterday was a hard day for us we lost many people. Many people lost their loved ones but their sacrifices weren't in vain we defeated the Kyuubi. It wasn't beaten instead I sealed into two new born babies since no man can defeat a Bijuu so I sealed it into 2 babies. The one has the chakra of the Kyuubi while the other has consciousness of the Kyuubi but fear not if you trust me then trust them. Because they are my children and they are the true savior of Konoha ones who will keep the Kyuubi at bay and save our daily lives" said Minato as many people irrupted in cheering but there were some boos as well. After his little speech was done he went home.
'Menma, with power given to you I wish you will use it for the good. If maybe, just maybe you are the one that Jiraiya-sensei mentioned, the child of prophecy' thought Minato before he glanced at his wife and his youngest. Kushina was cuddling Naruto and Naruto was smiling happily.
It has been 4 years since Naruto and Menma were born. And things between the two brothers were complicated. Menma would always bully and brag him about what he and his tou-san did. And Naruto hated when he does that, why? Because this idiot was wasting his precious time with his kaa-san. And that was unacceptable.
The reason why Menma did that was simple. Menma was a daddy's boy and Naruto was a mommy's boy. Naruto thought that Menma was jealous because he would always spend time with his mother while Menma would always spend time with his father.
At first it was just to take his mothers attention Menma would always do things to Naruto but he what he got from his mother wasn't what he was searching for infact it was quite the opposite. Kushina...
