Umbra is seen with Naruto, walking past Ichiraku, Umbra begins to talk" What do you mean, my chakra isn't controlled? This garb on me, is the ONLY way to control it." Naruto sighs"Your chakra isn't controlled, because you have no element assigned to it, it's just a black mass of energy insider your body, flowing through your chakra network." Umbra is puzzled" An element? You can assign elements to chakra?" Naruto nods in agreement"Mine is wind, just like my father, the late Fourth Hokage." Umbra wonders for a moment, then asks a question " Could you teach me? Or someone in this village, at least?"
Naruto smiles" I'm no teacher, but Kakashi is, he helped me unlock my element. and helped me infuse it with my signature jutsu, the Rasengan." Umbra is shocked" Rasengan? The same move used by Jiraiya, who learned it from your father?" Naruto nods" The very same, and only three in the world know it now, Kakashi, Konohamaru, and I." Umbra is intrigued " If I find out my element, can I be the fourth, in that list?" Naruto is shocked" You're asking me to let you learn a jutsu, that took my father three years to master,and three weeks for me? What. are you going to master it in three days?" Umbra smirks"If I could tame a chakra far worse than yours, in my opinion, I think I could learn a jutsu that requires a ball of spinning chakra."
Naruto is happy at the fact that Umbra reminds him, of himself"Well, I guess you have to find your element first than, eh Umbra?" Umbra smirks" Point me to Kakashi, and I'll
be back later." Naruto points toward what seems to be a huge memorial stone,and Umbra teleports there, in a white puff of smoke"Kakashi, teach me how to find my element,I want to incorporate into the Rasengan." Kakashi's eyes widen in fear, and thinks"He's so much like Naruto, a little to much, I just hope that this doesn't lead to a second Sasuke." Umbra is waiting for a response"Well?" Kakashi replies" I will. just promise me, that you'll develop your own jutsu with the knowledge, and not over depend on the Rasengan." Umbra nods in agreement"I will Kakashi, do you mind if I call you sensei?"
Kakashi seems happy"Not at all Umbra." Umbra smiles" Alright, Kakashi-sensei, shall we begin?"
Umbra is seen holding a piece of paper, no bigger taller than his middle finger,and no wider than two fingers, umbra begins to speak"So, depending on what happens to this paper, determines my element?"Kakashi nods"Concentrate, free your mind of all distractions,and focus on trying to get a bit of your chakra to flow into that piece of paper." Umbra nods, and does as requested, the paper turns pitch black, than burst into flames" What element is that Kakashi-sensei?" Kakashi is shocked, and knows that there isn't a chakra type like that, but remembers something his teacher Yondaime has said "Kakashi, besides the basic chakra elements, there are hybrids, these hybrids are by no mean rare, but can be accessed by a person who has one of the two basic elements to use that hybrid element." Umbra is patiently waiting for an answer, then he decides to dwell in his thoughts until he receives an answer, Kakashi realizes which element Umbra possesses" Umbra, your element is Blaze, a hybrid of fire and lightning."
