Legend_awakened_99
You are right bro. But I cannot awaken rinnegan only with Hasirama cells and Mangekyo shringan. If it would be possible Obito should have almost awakened rinnegan. But he didn't have EMS. So he needed Madara's rinnegan to become ten tail Jinchuriki later . That's why I included EMS plot in the story .So that I can awaken both rennigan in my eyes using Hasirama cells in the later story . Note: Sage of six paths will only give me one rinnegan....
When he gets hasirama cells he wont need itachis sharingan because hasirama cells take away blindness from mangekyou and also strengthen it also he might be able to use wood realise even if its a weakend version of it like the one obito or yamato used also how old is he right now and how long is it till the start of shippuden happens
