In recent Boruto chapter Naruto actually said what're these sticks when Jigen hit him with that....The dude literally forgot about pein, I mean he himself had that stick in So6p mode how come he forget it.....Just how Rusty can a guy be
Yh it could be different but Naruto was acting like this whole thing was foreign to him...So that was kinda off ....You know considering the fact that he himself had one in So6p mode it's really really really weird he shouldn't be this rusty..if i remember right, pein's injected chakra and naruto's erased things,so jigen's rod absorbing chakra highlights that it's a different jutsu
