Kakashi's Cute Little Genin are Terrifying (джен)

Hatake Kakashi has been pulled off of ANBU duty to become a jonin teacher. In effort to keep himself at least somewhat entertained as well as to prevent from having to put too much effort into training his genin, he informs them that a jutsu he made up on the spot is too difficult for them to preform and has them practice until he deems them ready. Meanwhile, Team 7 begins taking after Kakashi, and that includes being interested in this jutsu of his as well.
AKA: Kakashi ends up training his team by trying to not train them, the Leaf Village is convinced Kakashi's making mini-Kakashis out of his students, and enemy nin become scarred for life.
