The sky inside Energy's domain did not have a sun, yet everything glowed as if light itself had chosen to live there permanently. The ground shimmered in soft gold, smooth like polished glass but warm like it understood existence on a personal level. Kanetaro lay flat on his back in the middle of it, staring upward with the expression of someone reconsidering every life decision that had led him to cosmic boot camp.
He blinked slowly and exhaled through his nose. "I just want it officially recorded," Kanetaro said lazily, squinting at the glowing sky as if it had personally offended him, "that if this is heaven's idea of a training facility, the interior designer needs to be fired," he added in a tone thick with theatrical disappointment.
"You destabilized three minor spatial layers while unconscious," Energy replied calmly from somewhere behind him, their voice smooth and unhurried as they materialized without sound, their form flickering faintly at the edges like reality was buffering them in high definition.
Kanetaro turned his head slightly but didn't bother sitting up yet. "So what I'm hearing," he said thoughtfully, raising one hand toward the sky as if presenting evidence in court, "is that my nap had impact," he continued in a smug tone that suggested he was seconds away from applauding himself.
"It had consequences," Energy corrected evenly, folding their hands behind their back with the composure of someone who had never once tripped over their own feet in public.
Kanetaro finally sat up, stretching his arms overhead with a dramatic groan. "You say consequences, I say influence," he replied casually, brushing imaginary dust off his shoulder while offering Energy a sideways grin that was entirely too relaxed for someone inside a divine dimension.
Energy observed him for a moment, their glowing eyes narrowing slightly. "The God of Death has been eliminated," they said steadily, the humorless weight of the statement settling into the golden air.
Kanetaro's grin faded just a fraction. "Yeah," he said more quietly, resting his elbows on his knees, "Kuro really walked into the admin office of the afterlife and said 'this system update is unnecessary'," he added in a low, impressed tone.
"Death itself remains," Energy clarified patiently, lifting one hand as a small sphere of shifting light formed above their palm, rotating with delicate precision. "The God of Death regulated the law. The law still exists."
Kanetaro tilted his head. "So the system is running," he said slowly, tapping his chin as if solving a puzzle, "but there's no moderator," he concluded in a thoughtful voice.
"Yes," Energy replied simply, though the faint pulse of light around them suggested concern buried beneath their composure.
Kanetaro whistled under his breath. "That's messy," he said, shaking his head with exaggerated sympathy. "Souls out there buffering mid-transition like bad Wi-Fi."
Energy stared at him. "That metaphor is disturbingly accurate," they admitted in a dry tone that almost—almost—hinted at humor.
Kanetaro stood, rolling his shoulders as if preparing for a casual jog rather than divine combat training. "He's not just killing gods for fun," he said slowly, his usual playfulness giving way to sharper focus. "He's stress-testing heaven. He wants to see how much pressure it takes before the cracks spread."
"Yes," Energy confirmed quietly, their glow dimming for a fraction of a second.
"And he wants you," Kanetaro continued, meeting their gaze directly now, his voice steady. "Not a fragment. Not borrowed power. The full source."
Energy did not look away. "He believes that if he controls Energy entirely, he will become existence itself," they said evenly, though something faintly irritated flickered beneath their calm.
Kanetaro let out a low breath. "That's not ambition," he muttered. "That's main-character delusion."
Energy blinked. "Explain."
"It's when someone thinks the universe is a side character in their personal story," Kanetaro replied smoothly, crossing his arms with a small smirk. "Kuro's out here trying to rewrite reality like it's a group project and he doesn't trust anyone else to do their part."
Energy's expression shifted ever so slightly. "You speak boldly for someone who cannot yet control his own output."
Kanetaro placed a hand dramatically over his chest. "First of all," he said in mock offense, "that was uncalled for. Second of all, growth takes time."
"Time is unstable at the moment," Energy responded coolly, raising one hand.
The ground beneath Kanetaro lit up instantly with intricate patterns of intersecting circles and lines. The air in front of them split open cleanly, a vertical seam of white radiance tearing through space like a surgical incision.
Kanetaro stared at it. "If that portal leads to cardio," he warned suspiciously, pointing at it with narrowed eyes, "I will simply pass away again."
"It leads to calibration," Energy replied calmly.
"That sounds worse," Kanetaro muttered.
Without further warning, a concentrated beam of white energy shot from the tear directly toward him.
Kanetaro yelped and dove sideways, rolling across the glowing floor before scrambling back to his feet. "We didn't even stretch!" he shouted in disbelief, brushing his hair back with wide eyes.
"You requested growth," Energy said evenly, launching another beam with precise control.
Kanetaro twisted, barely avoiding it. "Yes, but like gradual growth," he protested, his tone incredulous as he ducked a third blast. "This is not a tutorial level. This is final boss behavior."
Energy's eyes glowed brighter. "Your instability makes gradual methods inefficient."
Another beam grazed Kanetaro's shoulder. He stumbled but didn't fall. Instead of burning, the contact vibrated through him, resonating in his chest like a tuning fork struck too hard.
He froze mid-step. "Okay wait," he said, lifting his glowing hand slowly, his voice shifting to alert confusion. "You're not attacking me."
"No," Energy replied calmly, lowering their hand slightly.
"You're syncing me," Kanetaro realized, staring at the faint light crawling over his skin.
"Yes," Energy confirmed, their tone steady but firm. "Your power leaks because you resist its rhythm. Energy is not meant to be forced. It is meant to be aligned."
Kanetaro took a slow breath. "So I've been brute-forcing cosmic Wi-Fi," he muttered.
"That metaphor is again disturbingly accurate," Energy replied.
Another beam shot toward him. This time, instead of dodging, Kanetaro raised his palm.
The beam struck.
Instead of exploding outward, it curved slightly, bending around his hand before dispersing gently into the air like mist dissolving at sunrise.
Kanetaro blinked at his own hand. "Oh," he said softly, genuine surprise in his voice.
"Do not react," Energy instructed calmly. "Control."
Kanetaro inhaled again, slower this time. The vibration in his chest steadied. The golden ground beneath him stopped flickering in response to his presence.
Energy launched three beams simultaneously.
Kanetaro pivoted smoothly, redirecting one with his palm, dispersing another with a subtle twist of his wrist, and allowing the third to skim past him without resistance. His movements were still imperfect, slightly dramatic, slightly overconfident—but more controlled.
He exhaled and smirked faintly. "Okay," he said, rolling his neck, "I see the assignment."
Energy lowered their hand. "You are improving," they admitted, though their tone remained composed.
Kanetaro grinned. "Say that again but with more enthusiasm."
"I will not," Energy replied flatly.
Kanetaro laughed, the sound echoing lightly across the endless golden plane. "You know," he said, glancing up at the glowing sky, "Kuro's probably not even moving right now."
Energy tilted their head slightly. "Explain."
"He killed the God of Death," Kanetaro said slowly, folding his arms as his gaze sharpened. "That alone destabilizes heaven. He doesn't need to rush. He's watching the cracks spread."
Energy was silent for a moment.
"He is calculating," they said finally.
"Exactly," Kanetaro replied. "He's not chaotic. He's patient. That's scarier."
Far beyond the radiant domain of Energy, beyond heaven's strained architecture and the subtle distortions rippling through divine layers, Kuro stood at the edge of a fractured celestial platform. The sky above him flickered faintly where unseen laws trembled without their regulator.
He did not move.
He did not rush.
His coat shifted slightly in a silent wind that carried fragments of dissolving spiritual residue. His eyes reflected distant distortions spreading like hairline cracks through glass.
He observed.
He analyzed.
The elimination of the God of Death had not been impulsive. It had been a test. A variable removed to measure systemic resilience.
His fingers flexed once, slowly, thoughtfully.
"Not yet," Kuro said quietly to the empty horizon, his voice calm and measured, carrying neither arrogance nor hesitation.
Back in the golden expanse, Kanetaro rolled his shoulders and faced Energy again. "Alright," he said with renewed determination and a crooked grin, "if he's planning to become existence, I guess I'll have to become inconvenient."
"That is not a strategy," Energy replied calmly.
"It's a vibe," Kanetaro corrected confidently.
Energy stared at him.
Kanetaro's grin widened. "Don't worry," he added, lifting his hands as faint controlled light gathered around them. "By the time he makes his next move, I won't just be leaking power. I'll be fluent in it."
Energy's aura brightened slightly, the golden world humming in quiet approval.
Training resumed, beams and resonance and laughter mixing in a strange harmony, while far away Kuro continued watching the universe strain under subtle imbalance, waiting for the precise moment when pressure would turn into fracture.
And for the first time since the God of Death fell, heaven was not the only thing preparing for what came next.
