The wake-up call wasn't the sun; it was the sensation of his own skin trying to detach itself from his bones.
Kaelen lurched upward in the cramped bed at Mother Martha's, a choked gasp escaping his throat. The air in the room was humming—literally. Small, jagged sparks of blue static danced across the moth-eaten blankets, and the wooden floorboards groaned as if a heavy weight were pressing down on them.
The "Magic Fever" had set in.
It felt as though the Lacrima fragment Hades had forced him to swallow was still sitting in his gut, a miniature sun radiating waves of raw, unrefined Ethernano. His magic container had indeed expanded, but the new walls were thin, raw, and bleeding energy. Every time he breathed, the space around his hands rippled involuntarily, creating tiny, flickering rifts that swallowed the dust motes in the air before spitting them back out.
Control it, he hissed to himself, clutching his head. Focus.
In his past life, he had learned that the mind was the anchor for energy. But his ten-year-old body was a faulty circuit board. He tried to "clamp down" on the leak, but the pressure was immense. His vision was swimming—even without the Sharingan, the world was too bright, the sounds of the canal outside too sharp.
A heavy knock at the door made him jump, nearly triggering a spatial collapse of the bedside table.
"Kid? You dead in there?" Mother Martha's voice was muffled by the thick wood. "The room smells like a thunderstorm, and the cat's hair is standing on end. I don't want no fires in my house."
Kaelen gritted his teeth, forcing the static to pull back into his skin. The effort made his vision go white for a second. "I'm fine," he managed to call out, his voice sounding like it had been dragged over gravel. "Just... practicing. It's under control."
"Better be," she grunted, her footsteps receding down the hallway. "Jewels don't pay for smoke damage."
Kaelen slumped back against the wall, drenched in cold sweat. He waited until the tremors subsided, then reached into his spatial fold to pull out a skin of water. He drank deeply, the coolness doing nothing to quench the fire in his veins. He looked at his hands; they were steady, but he could see the faint blue glow beneath his fingernails.
He had survived the first night. But the hunger Hades spoke of was real. He could feel it now—a hollow, aching void in his chest that wasn't there before. The 'cup' was larger, but the thirst was deeper.
By late afternoon, the fever had subsided into a dull, manageable ache. Kaelen slipped out of the boarding house, avoiding the main streets. He felt heavier, his footsteps leaving deeper impressions in the mud. The Ethernano was settling into the new 'cracks' of his container, hardening like cooling iron.
He crossed the bridge and headed back toward the western forest. The city of Magnolia seemed smaller today, less significant. The boisterous noise of the legal guilds felt like the buzzing of flies compared to the cold, silent gravity of the man waiting for him in the woods.
He found Hades in a different clearing—this one was barren, a circle of scorched earth where nothing grew. The old man was standing in the center, his staff planted firmly in the dirt. He didn't look up as Kaelen approached.
"You look like a drowned rat," Hades said, his voice flat.
"I survived," Kaelen replied, stopping ten paces away. He pulled his hood back, meeting the man's single eye with a gaze that had grown noticeably harder in just twenty-four hours.
"Survival is the bare minimum," Hades said, finally turning to face him. He studied Kaelen, his gaze lingering on the boy's chest, where the mana was swirling in a chaotic, newly-formed vortex. "The Lacrima did its work. Your capacity has nearly doubled. But you are leaking like a broken faucet. If we don't seal the container, you will burn out your nervous system before sunset."
Hades raised his staff, and the ground beneath Kaelen's feet began to glow with a dark, violet light.
"Yesterday, you learned how to break. Today, you learn how to condense. Lightning is not just a discharge, boy. It is a focus."
"Magic is intent. And your intent is as loud as a scream. But you are trying to hold the lightning in your hand like a ball. That is why it fails. You must compress the space around the lightning to keep it from dissipating. Use your spatial magic to create a vacuum. Only then will the friction reach a lethal temperature."
Hades pointed his staff at a large, jagged boulder on the edge of the clearing. "I don't want to see sparks. I want to see a hole. And if you fail, the feedback from the spell will take your arm. Consider that your motivation."
Kaelen looked at the boulder, then at his own hand. He felt the cold energy of the Sharingan beginning to rise. He didn't fight it. He let the crimson take over, the two tomoe spinning with a frantic, analytical speed.
He reached out, his hand open. He began to draw the Ethernano—not as a flood, but as a needle-thin stream. He felt the pressure building, the heat rising.
Compress the space, he thought, recalling Hades' words.
He used his spatial magic to create a microscopic "shell" around his palm—a localized fold that trapped the air. Inside that shell, he began to vibrate his mana at a frequency that made his teeth ache.
Bzzzzzt.
The sound wasn't the sputtering crackle from the day before. It was a high-pitched, piercing chirp. A single, jagged bolt of blue lightning appeared, held in place by the spatial vacuum. It didn't spread; it screamed.
"Now," Hades commanded. "Strike."
Kaelen lunged. He didn't just swing his hand; he put the weight of his entire soul into the thrust. The air around his arm distorted, the spatial shell and the lightning acting as a singular, devastating drill.
The impact wasn't a thud. It was a shriek.
Kaelen's hand passed through the boulder as if it were made of warm wax. The lightning erupted on the other side, shattering the stone into a thousand fragments that rained down on the clearing.
Kaelen skidded to a halt, his hand smoking, his breath coming in ragged gasps. His arm was numb, the skin red and angry, but it was still there.
He looked at the hole in the rock, then at Hades.
"Better," Hades said, his expression still unreadable. "You have moved from a child playing with toys to a novice with a weapon. But that strike cost you half your remaining mana. In a real fight, you would be dead a dozen times over."
Hades stepped closer, the shadow of his staff falling over Kaelen.
"The container is larger, yes. But now we must teach you how to fill it from the Abyss, rather than your own blood. We are done with the basics, boy. Now, we begin the real work."
Kaelen looked at his hand, then at the man he was calling master. He knew he was walking deeper into a trap. He knew Hades was using him for something. But as he felt the cold, sharp power of the lightning still hum in his veins, Kaelen didn't care.
"Give me more," Kaelen whispered, his red eyes burning in the twilight.
Hades smiled, and for the first time, it looked like a greeting from a fellow monster. "As you wish."
-----
One month had passed since the night the world cracked open in that forest clearing.
Thirty days of brutal, silent evolution.
Kaelen stood in the same scorched circle of earth, but he was no longer the staggering, feverish child who had vomited in the dirt. He stood perfectly still, his breathing so shallow it was almost non-existent. The humid air of Fiore no longer felt heavy or intrusive; it felt like a medium he could manipulate.
He didn't need to check his reflection to know he looked different. His face had lost the last remnants of childhood softness, replaced by a sharp, predatory focus. His body, though still small, was corded with a new kind of density.
The "leaking faucet" was gone.
Under Hades' watchful, singular eye, Kaelen had spent the last four weeks learning the hardest lesson of all: efficiency. He had stopped fighting the Ethernano and started commanding it. His magic container had stabilized, the "walls" of his vessel hardened into something akin to cold steel. He could now cycle his energy with a rhythmic, pulsing flow that kept his reserves from draining into nothingness.
"Again," Hades' voice drifted from the shadows. The old man hadn't moved from his spot near the ancient oak, his staff casting a long, violet shadow across the grass.
Kaelen didn't respond. He simply closed his eyes and inhaled.
When he opened them, the two-tomoe Sharingan snapped into existence. It was no longer a frantic, mana-eating struggle to keep the eyes active. The red was deeper, the black marks spinning with a calm, hypnotic precision. To Kaelen, the world became a grid of possibilities. He could see the wind currents, the structural weaknesses in the trees, and most importantly, the jagged, terrifyingly vast flow of Hades' power.
He reached into the air. He didn't tear at it this time; he slid his fingers through the fabric of reality.
A spatial rift opened—not a jagged hole, but a clean, silent slit. He pulled his sword from the void, the iron already humming.
Friction.
He surged the lightning through his hand, but instead of the loud, chaotic crackle of a novice, the blade emitted a high-frequency whine that was almost ultrasonic. He wrapped the spatial "shell" around the lightning, compressing it until the blue glow turned white.
He didn't lunge blindly. He used his eyes to calculate the exact path.
Spatial Displacement.
Kaelen didn't just run; he "flickered." He folded the space between himself and a target dummy Hades had constructed out of reinforced ironwood and stone. He appeared five feet to the left of where he had been, the air popping as reality rushed to fill the gap.
The strike was silent.
The blade, shrouded in the compressed lightning vacuum, passed through the ironwood dummy as if it were air. He didn't just make a hole; the high-frequency vibration of the friction caused the internal structure of the stone core to disintegrate.
Kaelen skidded to a halt on the other side, sheathing the sword back into the spatial rift before the first fragment of the dummy even hit the ground.
He stood upright, checking his internal state.
25%. A month ago, that move would have left him gasping on the ground, half-dead. Now, it cost him a quarter of his energy. He could do it four times and still have enough left to run.
"Your refinement is adequate," Hades said, stepping out from the trees. He looked at the shattered remains of the dummy, then at Kaelen. "You have stopped trying to drown the world with your mana. You are beginning to understand that true power is found in the point of the needle, not the weight of the hammer."
Kaelen deactivated his eyes. The familiar throb was there, but it was a dull ache, a companion rather than a disability. "The container feels... solid now. But it's still small. I can feel the limit."
"The limit is a horizon, boy," Hades replied. "As you move toward it, it moves back. But you are no longer an insect. You are a weapon. A weapon that needs to be tempered in more than just shadows."
Kaelen looked at his hands. Over the last month, he had developed a strange, transactional relationship with Hades. The man didn't talk about 'bonds' or 'friendship.' He gave Kaelen knowledge, and Kaelen gave him results. It was cold, efficient, and exactly what Kaelen needed. He had managed to keep the more "biological" secrets of his eyes to himself, framing the Sharingan as a high-tier visual magic, but he knows Hades isn't stupid; he probably knows his Sharingan.
"What's next?" Kaelen asked.
"You have spent enough time in this forest," Hades said, tapping his staff. "The city of Magnolia is a den of mediocrity, but it is also a hub for information. You have the gold from your emeralds, and you have the strength to defend it. You will return to the city. You will observe the 'Legal Guilds' and learn their movements."
Hades leaned in, his single eye piercing through Kaelen's black gaze.
"I have taught you how to kill. Now, I want to see if you can walk among the sheep without showing your teeth. You will stay at that boarding house and continue your training in the dark. I will find you when the time is right for a real test."
Kaelen felt a prickle of caution. "You're letting me go?"
"I am letting the bird fly to see how it hunts," Hades said with a thin smile. "Do not disappoint me, Kaelen. You are an investment. And I do not like losing my capital."
Without another word, the shadows around Hades seemed to rise up and swallow him whole, leaving Kaelen alone in the clearing.
Kaelen stood there for a moment, the silence of the forest returning. He felt different. He is no longer as weak as before, but he is still not strong enough. He is grateful for Hades' teachings.
He walked toward the edge of the woods, his cloak fluttering in the cool breeze. The lights of Magnolia were visible in the distance, flickering like a field of fallen stars.
He stepped onto the road, his boots clicking on the stone with a steady, rhythmic confidence. He was ready to start the next phase of his plan. He needed a master, and he found one. Now, he needed a target.
