Yukina was talking to Kurama when Botan flew over and handed Yukina a poem. That said,

I'm The One

I'm the one, who no one knows,
I'm the frozen rose.
I'm the one you're searching for,
I'm the one who loves you more.
I'm the one who never dared to care.
I'm the night; you're the light,
I'm the shadow; you're the flower in the meadow.
I'm the black bird; you're the blue,
We have differences galore.
I'm your brother we have the same mother.
I'm the one who'd rather die then see you cry.
I'm your brother cursed because I have a father,
I'm the one forbidden to return, rejected for being born.
I'm the one who'll watch over you, what a beautiful view.
I'm the one who'd give up everything to keep you safe.

" Botan. Where did you get this? Who wrote it? " Yukina said softly. " I don't know who wrote it but I found it with these." Botan said as she pulled out Hiei's sword, cloak, and bandana. " There was also this." Botan said pulling out another piece of paper and handing it to Yukina, it said:

Yukina,
I know Botan will get this, the poem, and my things to you. I won't need them where I'm going. For it would be useless to fight back. It would just make death so much more painful. Little sister don't cry for me for a I don't fear death but welcome it. Take care and have a long and joyful life.

Your Brother

" Botan I think. I think Hiei is my brother. " Yukina said.
" He is Yukina. He is. " Botan said.
