Excellent response! Yes, you are indeed correct about inflicting Genjutsu in such a way so that your opponent would not notice it. As Genjutsu is not real, there are often times flaws within them, that we ourselves must straighten out so that it is a valid attack upon the battlefield.
As for creativity, you slightly touched upon it, but remember, the enemy's mind is the paper, and your own imagination, the pencil. There are no limits but your own.
Kurama Clan...hm. I forgot who had those types of bios.
Nonetheless, let us start simple. How might one release themselves from Genjutsu? What ways are there?
