do you guys remember that one time people argued whether or not sasuke achieved PS with EMS during the juubito fight? i do. we argued whether or not he achieved it because it was boosted by kurama's chakra. sasuke fans argued that getting more chakra doesn't make the susano evolve, so people had to drop it. i think that is now debunked now. susano does indeed evolve when more chakra is gained. in this current chaper, sasuke's PS evolved into a whole new form of susano as soon as he gained bijuu chakra.
