A year before the invasion of the village, when Nobu received the quirk, barely noticing its temperature effect, he rushed to study its properties, secrets, functions, types of effects, in general, about everything. Unfortunately, he did not have access to high-tech measuring devices, laboratory scanners and analyzers, which are written about in books. He has too few books, but a lot of time, in a general education book on physics, a couple of terms related to heat exchange, thermodynamics were mentioned. Had to study by empirical research or "trial and error".
The first two months were spent confirming the nature of the quirk. He felt how the already absorbed heat was stored inside his quirk, an incomprehensible amount. Nobu realized that he did not feel the absorption of heat itself, so he could not understand where it was coming from, but guessed that from the Sun, because when he went into the shade, the storage filled up much more slowly. If we translate the sensations into mathematical terms, then in the shade it absorbs approximately ~75% less solar heat, and when indoors, it absorbs almost ~0%. And the absorption of solar heat occurs automatically. Almost like a solar collector.
An important discovery was also made. It could also absorb fire. Absorb it, and this was already visible. That is, flame, which is primarily a chemical reaction between fuel, oxidizer with the release of heat and light. Taking all the heat from the fire, it was extinguished and lost its light, the light in turn was visible to the eye and this reaction can be traced by the human eye. With "Absorption", the flame fades, even the coals go out, and the chemical reaction stops. Different amounts of heat are absorbed in direct proportion to the intensity of the chemical reaction.
The next four months were spent studying and training "Release". This is now the name of Nobunaga's skill, releasing heat, previously stored inside the quirk. Quite a complex skill, since the first release was purposeful and conscious, but the heat came out of the whole body at once. Nobu concentrated on releasing a small amount from his finger, then all his fingers, still trying to heat the water in the bucket. And only at the end of the sixth month from the moment of awakening the quirk, he managed to fully boil the bucket in a second. Through simple calculations, it became clear that Nobu's capabilities were limited to releasing energy at exactly 200 degrees Celsius per second.
The heat of the quirk does NOT harm the user.
Nobunaga felt an incredible surge of delight and pleasure at the end of the Basic stage of study. All this time, he wrote down the results of each experiment. He thought about what to call this power - "Ash" is the same as the pale color of his skin. It's time to proceed to the second stage, as he called Formation.
"Unlike the previous stage - Basic, Formation does not aim to study properties, but to create combinations and skills. Also, this quirk has some weaknesses" The studied category of weaknesses of the Ash quirk include:
1) Uncontrolled absorption of solar heat. Nobu cannot control it, it is absorbed automatically and passively. Therefore, it becomes cool near him. In the shade by 25% less, in a closed room by 99.9% less. At night - 50% less, even at night the planet continues to receive heat from the Sun.
2) The skin becomes irritated under the influence of ultraviolet radiation from the Sun due to albinism. Brings discomfort, it is difficult to concentrate.
3) Heat cannot be seen, so it is difficult to calculate the exact amount of absorbed and released energy. Worsens sensitivity to force and affects control.
4) If heat is stored in the quirk, then there is a limit, there is definitely a limit to storing maximum energy.
5)?
"Hmm" He thought about how to solve each of them. The second one immediately falls out, most likely it is innate. The first drawback of the quirk, which results in an even bigger problem when combined with the fourth problem. What happens if the storage limit is exceeded? Expansion or....explosion?
"To expand the storage, you need to either build up energy or spend it. What to do?" So far he had no idea what would happen. The storage holds a lot of energy, but there is a limit, he felt it.
Having gone far into the forest, he decided to practice, but while walking with thoughts, an idea came to him. "In order to take the unit of measurement of the storage size as a basis, you first need to empty it completely. I will feel it."
Having found a coniferous tree trunk lying on the ground, overgrown with moss. Stretching out his hand, Nobu activated the quirk to heat the tree from a distance. In a couple of seconds, the coals flickered, turned red and a flame appeared. "Haha, no matter how many times I say it, it looks cool." Nobu imagined how much mischief can be done with such power. No, not dirty tricks, but real accomplishments.
His plan was to release the entire reserve, no matter what it took. Of course, he wasn't going to burn the forest. It was too irrational and wasteful. He found a rock and moved away distance of four meters, and began to release heat gradually exceeding 200 degrees per second. This was also the best training in Release and control in general.
225....268....394....413....445 degrees, the rock began to gradually melt into lava, which was about to rush at him and burn everything here!
"Lava looks charmingly dangerous, but can I reabsorb the heat from it?" Heat rushed towards Nobu again and the lava began to solidify, forming solid rock. All the fire from the bushes and grass was absorbed. Only scorched earth and ash remained. Nobu smiled deeply to himself. A gift from Amaterasu herself, which at the same time is a curse for man. "Ha-ha! Wow. In the next step, we need to think about how to optimize, reduce, and better yet completely get rid of the shortcomings. Every weakness can result in failure or even death.
He did not notice the passive influence of the quirk on his behavior.
Having melted more rocks and rock, he reached the limit of the storage and remembered the approximate feeling. The amount of stored heat will be calculated in Celsius. He went out into the sun's warmth, feeling how the storage began to fill. Nobu voiced the approximate amount.
- 200 Celsius ... 300 .... 450 ..... 525 ..... 650 .... 850 .... - Nobu was surprised, a new snag was revealed. The longer he is under the sun's rays, the faster the heat accumulates, insignificantly, but still. But being under ultraviolet light was burning and unnerving.
"It's too early to draw conclusions, I'll ask Nezu to go to the city to buy a couple of books." Nobu activated Absorption on all the energy released on the rocks and went down the rocks. "There are a lot of plants growing here, but I won't eat anything, even though I'm hungry. Grandma said a lot of scary things that happen to mushroom pickers."
The white-haired boy saw wild snow monkeys jumping on the trees, this group was aggressive and surrounded the unworried boy. "Ha-ha, just like humans." They bared their teeth and decided to drag him into the forest. Nobu did not underestimate the sharpness of the fangs and melted the macaque with a released five-hundred-degree wave, its eyes instantly flowed out, and its fur was charred, its skin peeled off. The other macaques, looking at this, were not so much afraid, but rather it made them even more angry. They were very fast, Nobu released heat around himself, burning the soil and grass so that they did not come too close. "Phew. Th-that was strangely scary... yeah."
Noby tried to hide, but they pursued him, not allowing him to leave. They won't forgive someone who killed their kinsman in a second. "Annoying macaques" Nobu tried to think of something until a stone flew at him.
- Ow!
- Ughaa-haa! - an enthusiastic roar was heard.
One macaque thought of throwing a stone at him, since he couldn't reach it. The air around Nobu's hair emitted a glow from using a quirk, which marked the beginning of overheating. This gradually began to anger him. All the macaques began to throw stones at him, at the little white-haired boy. They hit him in the forehead, from which blood began to flow. "Tired!"
The heat intensified so much that the air around Nobu became too fast. The albino thought of concentrating Release in his finger, from which a jet of air flew out in a second, creating thrust. This pushing force helped Nobu to avoid the hail of stones hanging over him, but in doing so, the Albino flew far beyond the trees and crashed into the bushes. "What is this?" He did not have any special thoughts about it, he needed to run away before the macaques came running.
Finally having gone far enough from the macaques, he laughed.
- Ha-ha-ha! Almost died from some monkeys! And how that monkey melted like butter... - He was amused by the situation itself, as well as the funny death of the macaque. He compared them as people, finding their behavior familiar: they also live in a heap, they can probably also stupidly die counting on an easy outcome. Nobu did not have enough knowledge to understand what effects happened to him, for a deeper understanding, books are needed.
Arrogance grew commensurate with strength, Ash's quirk began to bend, acquiring its alter ego under the influence of its own power. It will begin to strive to take over the body very soon, overpowering Nobu, growing roots in him until he notices it. The first sign of the abnormality of the quirk were horrors and blood from the nose.
