I think whole purpose of todays chapter is to draw away atention from that shadow figure, because if PS is only temporary not permanent, it is meaningless.. Naruto is doing good against Kaguya even 1v1 didn't even need that Kakashi Susano'o.. So question is: who is shadow figure, i could really be thinking that's Tobidara but srsly.. I don't see any logical answer.. IT IS NOT SAKURA SHE IS TOO CLOSE, It could be: Hamura or Tobidara.. Noone else could come in that dimension.. I guess that is..
