Do not own Naruto.
"I will give up my soul for you to seal the demon fox and demented bat demon in my son." Minato was saddened by the fact Naruto would have to go through life without any family but there was nothing he could do about.
The Shinagammi laughed and answered "I give you a rare opportunity, for this seal requires one soul to be give for each entity sealed with in a single human because I bored if you take my place as a Shinagammi till my human body dies I will seal the fox in your son and seal the bat in my human body therefore, I will not have to eat your soul."
"I'll do it" he had been prepared to have his soul eaten but instead he ended up a temporary Shinagammi.
"Karada ga shōkan, Tamashī ga fukusei, Tamashī no haichi." Beside Naruto appeared a child she was wrapped up in black cloth her eyes where black mixed with icy blue and her skin was pale white. "Akuma shīru gijutsu" a seal appeared on Naruto and the girl's stomach you couldn't see the girl's, but it was there under the cloth. The Shinagammi disappeared and Minato fell down his soul having left his body. The Shinagammi reappeared but it looked different it had spiky blonde hair and blue eyes; he smiled down at the two children and disappeared. The boy was the first to awaken he looked around and started crying, his crying woke up his companion and she too started to cry. After about an hour they stopped crying and fell into exhausted sleep.
The next morning
Sarutobie was picking up bodies of the fallen last night, thankfully the Fox and bat demons had disappeared but many good shinobi had died. He saw Minato he hurried over but stopped short there in the Yodaime's arms where two babies suddenly he understood Minato had sealed the two demons inside his twins at the cost of his life. He would have to talk to Kakashi later about them. He walked up to the dead Hokage and picked up the children. When he picked them up two pairs of blue eyes opened up to look at him, both a picture of innocence. The boy smiled up at him, he smiled back. The girl seemed to be smirking up at him. He got the feeling that these two would be the source of many headaches.
This is more of an introduction than a chapter. Sorry for any incorrect grammar. I know this idea has been used many a times, but I plan in mine being a little different than others.
