Chapter 7... Sort of

Ah, D-ranks. Kakashi had almost forgotten what those were like. Dull make-work that helped teach teamwork to new teams. It also helped to serve as an effective disillusionment device. True, as a ninja, you did have to fight, and it was inevitable that at some point you would have to kill, but most of the time? Being a ninja could be boring, especially during peace-time. Stake-outs, guard duty for paranoid rich people, long-distance border patrols... Of course, while it could be boring, it was a good boring. There was enough death in the world without seeking it out. He knew why Minato-sensei was so fond of making them do D-ranks as often as possible during the Third War – It was better to contribute without contributing to the death toll, if you could.
It was also funny as hell watching your cute little genin team toiling away while you pretended not to watch from the sidelines.
