Training 4: A Force of Nature

Training 4: A Force of Nature is the seventh chapter of Season One, as well as of the series as a whole.

Plot
Kakashi begins teaching Matt the Transformation Jutsu. Kakashi states that this is a difficult Jutsu to master, in spite of being labeled E-Rank, and this is proven when Matt has trouble mastering the technique. As Matt becomes fatigued due to Chakra exhaustion, Kakashi explains that Chakra is a Shinobi's life force, and that if one would expend all of their Chakra, they would die. Matt and Kakashi talk briefly while Matt's Chakra recovers, discussing the hierarchy of Ninja Ranks. Matt eventually recovers, and with one final attempt, he masters the Transformation Jutsu.

Kakashi then goes on to explain Nature Transformation to Matt, displaying the properties of Chakra Paper. Matt uses the Chakra Paper, revealing his Primary Nature to be Fire. Kakashi then gives Matt a scroll containing many Fire Jutsu, officially concluding their training. Kakashi tells Matt to develop his own skillset, discovering his own strengths and weaknesses in the process by utilizing the techniques in the scroll. Kakashi promises he will be around if he is needed, and tells Matt that in three weeks, he will join Kakashi's team as an official member. Exhausted, Matt returns home and rests. He contemplates working with the scroll, but instead falls asleep.
