As his senpai's gaze is solely focused on him, Asuma thinks to himself, that he was indeed lucky that his senpai was listening to his explanation with utmost interest. With a bright twinkle in his eyes, Asuma looks happily at his senpai and notices her approaching him.
He then places his hands in his pocket and looks at his senpai, his gaze still fixated over her, trying to comprehend the infinite beauty and innocence of her face. He had never seen someone with such innocence on their face, an innocence which melted his heart. Her face had the warmth and light of the everglowing sun.He though to himself that she was truly a master of Katon, that she had perfected it with utmost brilliance that it was showing on her face and reflecting a beautiful aura around her.
As she approaches him and locks her arm around his, Asuma feels a bit shy and his face turns red. But, being the confident and badass guy he was, he controls his expression and it changes to that of a calm, radiant one. As his senpai gestures him to lead the way, Asuma starts walking along with her.
As his senpai finishes speaking, Asuma says,
"Thank you senpai. It was you who helped me go deep in describing fire. Indeed. I do feel it will be very interesting for both of us, because never has one helped me find my inner side. Never could I describe things in such a beautiful manner until you came. It's all thanks to you!
Here's my explanation on Fire:
Fire is the rapid oxidation of a material in the process or combustion, basically releasing heat and light. It needs oxygen, a high temperature, and fuel to burn.
Fire Release is one of the basic elemental nature transformations. It is performed by moulding chakra heated upto intense levels inside the stomach before releasing it via the lungs and mouth.In terms of raw potential, its considered the least versatile element as it excels in offensive capabilities, lacks in supplementary usage and is ill-suited to use as a defensive element. Despite this, Katon is the most ferocious element to contend with due to its sheer raw power. The heat of the element makes it capable of reducing earthen structures to molten mud, the parasitic nature of it means it preys on the oxygen within wind-based attacks to supplement the flames and even against its elemental superior, large-scale Katon techniques are capable of reducing large bodies of water to scorching mist of dense steam. The Katon element has little usage outside of destruction, to a certain degree its the hardest elemental nature to tame due to its uncontrollable nature.
Commonly associated with the Tiger hand seal, Fire Release consists of mid to long-ranged offensive techniques that cause combustive and explosive damage.The chakra nature is common among shinobi of Konohagakure in the Land of Fire, notably with the Sarutobi clan and Uchiha clan, the latter having been noted to hold a natural affinity for it. The Uchiha clan uses the technique, 'Katon:Gokyakuu No Jutsu' as a "coming of age" rite.
Uses
1)Fire can be used in along with Wind, to give power to the flames.
2)It can be used with Lightning, to change the weather conditions.
eg:Sasuke took advantage of the terrain and used Fire with Lightning, hence creating thunder clouds.
Strengths
1)Fire is strong against wind because the air feeds the flames.
2)As I said, it can be used with Wind Release, to increase the intensity and destructive power of the flames.
3)A Rank Fire>=A Rank Wind
4)A strong enough Fire jutsu can counter Water by turning it into steam which creates a hindrance.
Weaknesses
1)Fire is weak against Water as Water puts off the flames.
2)A Rank Fire<=S Rank Wind.

As Asuma finishes telling his senpai whatever knowledge he has on Katon, he closes his eyes and smiles again, her arm still locked around his.
