That morning, Kozai left Kurona at home, where she was in her dragon form (thank goodness), happily dining on a piece of meat he had gotten from the commissary where he got most of his groceries. He hoped she would at least take her time with the morsel... as attached as he was to her, he didn't want her stalking him today. He needed to work on the foundation of his training, and what better place to start than the training grounds? As he walked into the bright late morning sun, he turned toward a training grounds he knew where jonin would give chunin tips.
"This is a basic weaponry technique." He looked, and saw one of the old academy bullies - now a jonin, it seemed. It was just a thing of life... "The flying swallow. It takes normal chakra infusion just a step further, but not much. Normally, however, a useful thing to have." What was this... a basic chakra weaponry move he didn't know? How shameful. He felt that Kurona would never let him hear the end of it if she found out. He began to copy the chunin's moves, placeing his non-sword hand on the palm of his sword.
With a quiet swish, the blue aura would come into being. Perfect, now he knew another (albeit weak) jutsu. It wouldn't carry him through fights where he was forced to use Mumyo Jinpu Ryuu, but that was fine. This was a mere stepping stone to something else entirely.
