its just a question that must be done in order to make sure that you have an idea of what you are going to learn.
about the fire thing that seemed that was kinda incomplete.. When a Nara shadow jutsu is incomplete and a large source of light comes into play between the user and target, the advance of the shadow is slowed (B rank fire), halted (A rank Fire), or pushed back to user (S rank and Forbidden Fire).
As you can see, its not always defeated by a fire jutsu, it has different effects depending the rank.
ok less talk and more work, first i want you to try and manipulate your shadow by focusing some chakra into it and make it move around you.
