hi ok .. i got a good theory about rin where's rin ?? she died ; why ? she was the jinchuriki of kyubbi how ?? Spoiler: UCHIHA MADARA dit it ! he wanted kyubbi power ! so he did extract it from rin but couln't handle him with his own power . so he left to recrute some missing ninja having great abitlities and promising them a demon . so the forth deal with kyubbi and sealed him again and now Spoiler: UCHIHA MADARA is coming back to accomplishing his duty . and about rin being kyubbi container ..look at her she got some "scoth tape" ( ) on her cheeks ?? maybe she's hiding the same marks that naruto got ?? <--dont take the last one seriously ! and if she really is .. note that konaha always put a uchiha's as teamates for kyubbi container !§ ( proving the relation between uchiha's and kyubbi ) this was rin's story ! ps : i m ....of course ..........sorry if this has been posted before i searched but couln't find something near that cheers . feel free to answers or to complete it or criticize !
