(WILL REWRITE) The Being of Shadows

A male from our world was reincarnated from our world, into the Naruto universe. There are only a few problems. One, 'he' is during the time of ninshu. Two, 'he' can not age and can live for a long time. Finally, 'he' is not a he anymore. (THIS IS MY FIRST STORY SO EXPECT SOME ERRORS AND FOR STUFF TO NOT MAKE SENSE.)
