I ran on, I thought: ‘‘ I hadn't met Kakashi again, because then I wouldn't feel so lonely now. Whenever I like something, it is taken away from me. I can not stand it.
Besides, the Hokage knows, and soon the whole village I belong to Akatsuki and that will cause trouble. Not just from Leader-sama, with bad luck they'll kill me. But I knew from the beginning that if someone finds out where I am working, my death is approaching. ‘‘

~ In the Hokage office ~

Everyone stared where the 12 year old girl had just been standing.
The Hokage spoke up first: ‘‘ Kakashi what's going on here? ‘Hat The hatake did not miss the low threatening undertone, and said carefully:
‘‘ Well ‘‘, he started ‘‘ that was my little sister Hikari Yumi. I haven't seen her in 6 years. At that time we were both orphans, but I was made a Jo-Nin and could no longer take care of her ... ‘
‘‘ Nobody knew anything about you and she neither bears your family name nor does she look even remotely like you, explain that to me. ‘‘, Tsunade interrupted him.
‘‘ That's so ‘‘, the copy ninja started again ‘‘ nobody knew about her because she has a biju spirit in her and my family didn't want anyone to know about it.
Even the 3rd generation Hokage didn't know about it.
It's like it doesn't exist. Our family had decided that, because they didn't want the clan name to be contaminated by a ´monster´. That's how she got the name Yumi.
The reason that she doesn't look like me was the responsibility of the Biju.
It carries the 2nd part of Kyuubi with the name Vulona.
(Yes, yes I stole the name ...)
Does that answer your questions? ‘‘
The Hokage just nodded. The three young shinobi looked at their sensei with open mouths, because they had not expected THAT.

So that was it again. I know that Kakashi's story doesn't match the original, but it doesn't matter xD
Hopefully there aren't that many mistakes ...
Your Hikari-Yumi
