My Hero academia: Fire Dragon Slayer Hero

Chapter 2 - Growth

Soon after, exactly ten years passed in the blink of an eye. Izuku had been training diligently under the guidance of Igneel, who taught him how to absorb the Ethernano in the atmosphere through meditation. Slowly but surely, Izuku learned to utilize Ethernano, showing remarkable intelligence and adaptability, qualities that made Igneel regard him as a prodigy.

Izuku's talent and combat skills grew significantly, far surpassing expectations. Under Igneel’s tutelage, he developed a unique fighting style, blending the power of Fire Dragon Slayer magic with advanced martial arts techniques. Izuku had also been enrolled in a martial arts dojo, training rigorously even without a quirk, and mastering everything they taught him.

His progress was impressive. According to Igneel, if Izuku and Natsu, his fellow dragon brother, fought at the same age, Izuku would have the edge. However, Igneel also noted that Natsu had a unique ability to grow stronger as he fought, making any battle between them unpredictable.

[ A/N: If you consider the whole event of Mha took a few months and Izuku already became a force to reckon with means he is extremely talented in combat compared to Natsu who has been training since childhood. ] 

Under the watchful guidance of Igneel, Izuku embarked on a rigorous training regimen unlike anything he had ever experienced before. Each day was filled with challenges, from mastering control over his newfound abilities to honing his combat skills against formidable opponents conjured by Igneel's magic.

Inko stood by her son's side every step of the way, offering words of encouragement and unwavering support. She watched with pride as Izuku pushed himself to the limit, determined to become the hero he had always dreamed of being.

As weeks turned into months, Izuku's progress was nothing short of remarkable. His mastery over Fire Dragon Slayer magic grew stronger with each passing day, and he soon found himself capable of feats that once seemed impossible.

But along with his newfound power came greater challenges. Izuku faced trials that tested not only his strength and skill but also his courage and determination. Yet, through perseverance and sheer force of will, he overcame each obstacle, emerging stronger and more determined than ever before.

And as Izuku continued to grow and evolve, so too did his bond with Igneel. The dragon became more than just a mentor; he became a trusted friend, ally and father figure, guiding Izuku not only in the ways of magic but also in the ways of life.

Though it was likely due to Izuku being the only one who had access to the near-endless amount of Ethernano in the surrounding area, he almost became a central conduit after prolonged exposure to it. This vast reservoir of magical energy significantly accelerated his growth and mastery of Dragon Slayer magic, giving him an edge that even Natsu couldn't match.

However, this power came with a potential cost. Izuku learned that, unlike Natsu, he might actually become a dragon. The differences between the magical systems of his world and Earthland posed unique challenges. Igneel, aware of this transformation risk, had been working tirelessly to slow down the process and find a solution.

"Igneel-tou-san." Izuku asked one evening during their meditation, starting to call Igneel father to warm the non existing heart of the fire dragon king.

“What exactly will happen if I turn into a dragon?" Igneel's fiery eyes softened with a hint of concern. 

[ "If you turn into a dragon, you may lose your humanity, Izuku. Your mind and spirit could be consumed by the dragon within you.  We must avoid it." ] Izuku nodded, understanding the gravity of the situation. 

"What can we do to prevent it?"

[ "We need to find a way to balance the Ethernano within you." ] Igneel explained.
