Could Kakashi fly?

[Avonomemi]

Yes he could. If he was willing to use time training in it. Time that could be spent reading Icha Icha Paradise.

Nice one lol
OT: kakashi can, problem would be his chakra

 

[NarutoChangeSasuke]

It has no handsigns

How exactly is kakashi copying it?

He would understand how it works eventually.
