limited bloodline and kekkei genkai are the same

naruto has boil release that he used when he fought kaguya ( he got boil release from kokuo the five tails biju)

and he used yoton:rasen shuriken (which its lava style rasen shuriken that he got from son goku the four tails biju)

he also used magnet release rasen shuriken ( that he got from shukaku)

he has three kekkei genkais

kakashi has only 1 and its not his bloodline trait, he got it from obito

but having a sharingan doesnt give you a bloodline trait too

i mean kakashi just took obito eye, there is no change in his blood, but he is tagged as kekkei genkai

oh about ao,i think you are right, but this justu doesnt present in anime or manga so idk
