I don't mind Kakashi story 8 chapters long actually. It's good to take a time off from Naruto and his nonsense.

Especially I would like to see, when did Kakashi and his rivalry with Gai started. [img]i/expressions/face-icon-small-happy.gif[/img]

Love to see the yondaime (I bet he wasn't the hokage yet), and maybe Kakashi had a love one? Probably Obito is a girl (unlikely), but it would be a bitter sweet story if he/she was.

I bet we would most likely start at after the academy. Where we see Obito tied to the post, Kakashi and the other girl panting on the ground, and Yondaime taunting them for not being able to get the bells from him. [img]i/expressions/face-icon-small-smile.gif[/img]
