How Onoki able to fly?

[KesOnFire]

Only because of RSM. Onoki did it without needing huge power boost.

Yea I know but he was still able to fly....

 

[animals74]

well he has wind element since he can make dust release,
so maybe that + his rock weight thing

But why other ninjas never shown it?

Samurai is different than Ninja.

Ninja is everday people(farmer, store keeper etc) but Samurai is emperor soldier

Ninja used stealth but Samurai rarely do that as their attire is for heavy battle and not stealth base battle

Did you really just say farmers and store keepers are ninjas?
