yes it is the same as kuarami
i remember in the beginning of part 1 when kakashi was examining naruto ,sakura and sasuke , naruto’s clones caught kakashi and another was going to hit him ,kakashi used kuarami to swap places with one of naruto clones so naruto hit his own clone ,isnt that what sasuke does?
and the same as what everyone can do ,when he is going to be hit by an attack ,he swapes places with branch of tree
but the plot prevents everyone to use this jutsu in a real fight but now sasuke uses it as a rinningan ability lol
ftg is a summoning execpt for that there is no smoke when ftg user appears and disappears (summonning himself),so i guess that is because ftg is faster than normal summonning
the same with sasuke’s jutsu ,it is technically kuarami execpt for that there is no smoke when sasuke appears and disappears(swapping places)
i guess that is because sasuke’s jutsu is faster
i think next chapters will show more power to sasuke’s ability
whatever it is op jutsu and so does ftg
