Reincarnated As Young King of Meteor City(Meruem-HxH)

As the first rays of the morning sun began to paint the sky, the training yard was filled with an electrifying energy. Haruto's plan was as audacious as his spirit, and his crew had accepted his challenge with matching enthusiasm.

Koshiro, their elderly yet spry mentor, led the crew through the rigorous and disciplined training. He was well-versed in the art of Nen and understood that each person had their unique aura and Hatsu. Koshiro dedicated himself to bringing out their potentials and molding their unique abilities to match their persona.

Machi, Franklin, Kortopi, Pakunoda, and Shalnark were the ones to start, already displaying potential abilities. Machi, the graceful and silent observer, began focusing on her Transmutation ability. Her affinity for stitching was known to all, and she started incorporating it into her Nen, trying to create Nen Stitches that could heal wounds and reconnect severed body parts.

Franklin, a man of few words but immense strength, worked on his Emission techniques. His burly frame shuddered with each attempt to concentrate his Nen into his fingertips, a telltale sign of his progress towards forming his Double Machine Gun Hatsu.

Shalnark, the strategist, was often seen muttering to himself, his hands moving rhythmically in front of him as he practiced his Manipulation abilities. He was determined to control his environment using his Black Voice Hatsu, where he could manipulate others using his phone and antenna.

Pakunoda, the feminine, shrewd and composed member of the group, delved into her unique Specialization ability. She possessed the innate capability to read minds, a form of Psychometry. She could extract memories from others by touching them, a skill she was starting to hone meticulously.

Kortopi, despite being the youngest, showed a promising start. His Conjuration ability allowed him to replicate objects, a power he used to create Gallery Fake, an exact replica of any non-living object he touched.

Among Haruto's crew, training commenced with equal enthusiasm but with less progress. They were starting from scratch, their abilities yet to take shape. Each member had a unique aura, each carrying the seed of an extraordinary power, but they had only begun to tap into these reservoirs.

Uvogin, the silent titan, grappled with his raw strength, harnessing his energy to control his Nen. His commitment and intensity were palpable, the ground shaking with every exertion of his energy. A force to reckon with, his progress was eagerly awaited by everyone.

Nobunaga, with his calm and stern demeanor, took to his training with a quiet intensity. He often spent hours in solitude, focusing on his Nen, his silent dedication resonating in his every move.

Phinx, with his broad shoulders and steady gaze, took his training seriously. His endurance was commendable, spending long hours training without showing signs of fatigue. His determination was evident, his aura growing stronger with each passing day.

Feitan, the tempestuous one, proved to be a relentless student. His gaze always bore a fierce determination as he tirelessly worked on harnessing his energy. He had a wild and unbridled aura, and despite his quiet demeanor, his training reflected his fiery spirit.

Canary, the youngest but fiercely loyal follower of Haruto, took to her training with unwavering focus. Her aura was sharp and swift, like a sparrow in flight. Her small form held an immense strength, and her dedication to becoming stronger for Haruto was undeniable.

Amidst the swirling sands of the abandoned arena in Meteor City, six figures practiced their Nen with a relentless focus. Nobunaga, the samurai of the group, had honed his sphere of En, allowing him to predict and counter even the fastest of strikes with his swift Iaido technique. The air within the sphere seemed to thrum with power, the energy rippling as if alive.

"Nobunaga," Koshiro commanded, his voice as authoritative as the tides, "expand your En. Feel the flow of the world."

With a nod, Nobunaga centered himself. His Nen rippled outwards, an invisible shield reflecting the world around him. His Iaido, honed to perfection, now shimmered with the raw power of Nen. It was as if he was one with his blade, every twitch, every breath, mirrored in the silent steel.

Meanwhile, Uvogin, ever the embodiment of raw power, wrestled with his inner strength. He was a massive hulk of a man, stood like a granite monolith, exuding an aura of raw power that rattled the sand beneath him.  His entire form shook as he concentrated on increasing his Nen. His fists glowed with the intensity of a thousand suns. His developing Big Bang Impact technique caused shockwaves that echoed throughout the vacant battleground. Every punch, every move, fueled by his Enhancement abilities, radiated a fearsome energy that increased with each passing moment.

Phinx stood amid the swirling sands, eyes locked on a rock several meters away. Concentrating, he began to build his Nen, the energy pulsating around him with a relentless intensity. But no matter how much he pushed, he felt like he was hitting a wall. The rock remained motionless. His initial idea for a Hatsu was to utilize his strength, and channel his Nen to cause destructive impacts, but it felt lackluster, not befitting his role by Haruto's side.

He glanced towards Haruto, the young man merely standing, his eyes closed in deep concentration. Phinx noticed how effortlessly Haruto's Nen ebbed and flowed, like a river carving its way through the landscape. His sheer presence was a testament to an unspoken command. Phinx, filled with newfound resolve, breathed deeply. His Nen swirled around him, building into a cyclone, the raw energy engulfing the rock. It shattered, a testament to his new Hatsu: Ripper Cyclotron Supreme.

Feitan, a slight distance away, worked on his own Hatsu. His short temper and volatile nature were both a strength and a limitation. It made him unpredictable, but his power felt like an untamed storm. His original plan was to convert his rage into raw power, but Haruto's latent majesty triggered a fierce competitiveness in Feitan. If Haruto was to conquer the world, Feitan would stand by his side, not as a follower, but as a partner.

Feitan's fists ignited, not with literal fire but with his Nen, the air around him shimmering with the intense heat of his anger. His Hatsu, Inferno Ascendant, was a reflection of his explosive personality, turning his emotional energy into a deadly force.

Canary, her face hard with concentration, watched Haruto from the corner of her eyes. Her loyalty to him was unwavering, absolute. The Hatsu she wanted to create wasn't for herself, but for him. She wanted a skill that could protect him, a power to act as his shield.

Channeling her Nen, Canary focused on changing its properties. She imagined her Nen wrapping around Haruto like a second skin, an unseen barrier. And slowly, she could feel her Nen morph, becoming more flexible, more durable. The King's Shadow - a Hatsu perfectly crafted for Haruto's protection.
