Hiei makes everyone believe he is cold hearted towards everyone but actually he does. One day when he was spying on his sister, he notices a blue haired female demon playing with her and he can't stop following her until they eventually meet in person and from that day forward, he never let her out of his sight. Hello fellow stars I am a big fan of Yu Yu Hakusho and I loved all the fanfics made on the anime so I am making my own and I hope you all enjoy it.
