The True Children Of Prophecy
On the night of the kyuubi attack the sandaime hokage risked his life to seal the yin and yang halves of the kyuubi into two out of the three of the yondaime Hokages children, Natsumi and Natsuko. As Naruto grew up he was neglected in favor of his twin sisters. On the other side another boy by the name of Sasuke was also ignored for his prodigy of a twin Sachiko.
EMS/Rinnegan Sasuke, Mokuton/Senjutsu/Rinnegan!Naruto, both godlike in the future. Both will be based after madara and hashirama.
