The sharp, clean scent of fresh linen and lavender hung in the morning air, masking the faint, lingering metallic tang that seemed to cling to Kairo's palate like a phantom taste. He stood before the tall mirror in his quarters, smoothing down the high collar of his academy uniform.
Kairo exhaled a slow, quiet breath. "Well, anyway... it's my first day of college. Let me go now."
Before his fingers could leave the brass buttons of his coat, the temperature in the chamber plummeted.
A sudden, suffocating darkness bled into the room from the shadow of the doorway—a grotesque, towering void creature, its form shifting like swirling ink, its eyes glowing with a sinister, malevolent glare.
Instinct took over before thought could process the threat. Kairo's hand shot to his hip, drawing his blade with a sharp SHRING that cut through the silence. He lunged forward in a lightning-fast thrust, the steel whistling through the cold air.
The shadow figure squeaked, attempting an evasive scramble, but its balance failed. It tripped over its own dark mantle and crashed heavily onto the hardwood floor with an ungraceful, rattling thud.
Kairo stood over the fallen shape, his sword held in a rigid guard, his heart hammering against his ribs. Wait a second...
The torn black cloth parted to reveal a disheveled, thoroughly bruised face.
It was Akio.
"Nooooo!" Akio wailed, clutching the shredded edges of the enchanted cloak while lying flat on his back. "It had such good mana in it! A whole month's worth of compressed shadow magic... gone!"
Kairo let out a long, exhausted sigh, lowering his weapon and shearing it back into its scabbard with a crisp click. "Ahh... you idiot. You scared the hell out of me."
Akio sat up, dusting off his pants with a wide, impish grin. "But it was worth it! Hey there... wanna bunk classes today?"
"No, Akio," a deep, rumbling voice echoed from the corridor. "Not now."
The light in the doorway dimmed as a colossal figure stepped into the room. King Ariston stood in the frame, his posture imposing, his expression a stoic, unreadable mask.
Akio's grin evaporated instantly. He scrambled to his feet, bowing so fast his forehead nearly hit his knees. "O-Oh! I am so sorry, King Ariston! I didn't mean to—I was just—"
A low rumble vibrated in the King's chest before breaking into a rare, booming laugh. "Hey there. You can bunk one time... for seven days."
Akio paled, a cold sweat breaking out across the nape of his neck. "O-Ok... understood, Your Majesty."
Kairo leaned his head back, examining his adoptive father with a puzzled expression. He walked over, his eyes dropping toward the King's lower frame. "Woah... Father. Did you work out or something?"
King Ariston tilted his head slightly, his dark eyes fixing on Kairo with quiet amusement. "Why did you assume that, my dear son?"
"Your legs," Kairo said, pointing down at the sovereign's broad sabatons. "They're massive. They look like giant tree trunks now."
King Ariston offered a faint, enigmatic smile, stepping closer to rest a heavy hand on Kairo's shoulder. "Don't worry. I will make you work so hard during training that—"
Before the sentence could finish, Akio grabbed Kairo by the elbow, his eyes wide with absolute panic. "I am so sorry, but please don't include me in that monstrous training!"
Akio yanked Kairo backward, sprinting down the grand hallway as fast as his legs could carry them.
Kairo laughed over his shoulder, throwing his head back as they bolted past the high marble pillars. "Hey there, Dad! Catch me if you can!"
Akio's soul practically left his body as he ran. "What did you just say?! Ohhh, Kairo, you've killed us both!"
In a fraction of a heartbeat, a blur of motion cut off their escape route. A hand reached out and clamped around Kairo's shoulder, pulling him into a firm, sweeping embrace. But the moment the fingers made contact, Kairo's form dissolved into a subtle optical distortion—a illusionary decoy.
A low chuckle echoed behind them as the real King Ariston materialized at the end of the hall, effortlessly catching Kairo mid-stride and pulling him into a warm, heavy hug that nearly squeezed the breath from his lungs.
Akio skidded to a halt thirty feet away, waving a frantic hand as he backed toward the exit. "M-Meet me at the grounds, Kairo!"
As Akio vanished down the outer steps, a small, soft voice squeaked from the side corridor.
A little girl with bright, wide eyes and a trailing silk dress came running toward them. It was Princess Aria. She threw her small arms around Kairo's waist, giggling softly as she pressed her face against his coat, embracing both her brother and her father.
Kairo looked down at her, blinking in mild surprise as he patted her hair. "Woah... Aria, you're looking so old. It feels like just a few days have passed, but you've grown so much."
King Ariston looked down at his children, his expression softening into a quiet, wistful gaze as he patted Aria's head. "The same thing happens to me when I look at my hundred-year-old children... whenever they say to me that they are a hundred years old." He paused, his gaze drifting toward the high windows. "It feels like time just flies."
Kairo looked out at the golden sunlight streaming through the stained glass, a faint, inexplicable chill lingering beneath his ribs despite the warmth of the morning.
Ahh... Kairo thought, offering a quiet, small smile to himself. This world truly is weird.
Kairo adjusted the strap of his leather satchel over his shoulder, offering a rare, gentle smile as he took a step toward the grand archway of the palace estate.
"Okay, Father—bye-bye. It's my first day of school."
King Ariston stood still, his massive frame framed by the morning sunlight. He tilted his head slightly, his brow furrowing in genuine confusion as the unfamiliar phrase lingered in the air. "Bye-bye...?" he rumbled quietly under his breath, testing the sounds against his tongue. Then, a slow realization dawned across his stoic features. Awkwardly, the ancient monarch lifted a heavy, gauntleted hand and gave a small, stiff wave. "Ah... farewell."
As Kairo's fading footsteps echoed down the stone courtyard, the heavy oak doors behind Ariston clicked open.
Queen Ayame stepped into the morning light. Her long silk robes rustled softly against the marble floor, her presence quiet and serene, yet laden with an imperceptible weight. She reached down, gently lifting the young Princess Aria into her arms. The little girl rested her chin against her mother's shoulder, her breathing slow and rhythmic as she drifted into a peaceful nap.
Ayame's amber eyes—so like Kairo's—looked out over the peaceful, sun-drenched capital. The city below was humming with mundane activity, completely oblivious to the horrific slaughter that had transpired deep beneath its foundations just days prior.
"Oh, my husband..." Ayame murmured, her voice barely louder than the morning breeze. "Did you wipe out the entire memory of the land?"
Ariston did not turn around. His hands rested on the pommel of his greatsword, his dark eyes fixed on the horizon where the sun continued its unhurried ascent.
"Yes," Ariston replied, the rumble in his chest carrying a bitter, cold finality. "Otherwise... my greatest secret—a truth I never even dared reveal to you—would have been exhumed for all to see."
He fell silent for a long moment, the quiet stretching until the ambient rustle of leaves seemed unnaturally loud. When he spoke again, the sovereign's voice cracked with a rare, suffocating tremor of genuine vulnerability.
"But the true threat remains..." Ariston whispered. "Lucian. The smartest child of my entire bloodline. I am... terrified of him. Not because he can scratch me in direct combat—he knows he cannot. But because he won't target me at all." Ariston's jaw clenched tightly, his knuckles turning chalk-white against his hilt. "He will target the young. The innocent. He will slaughter the kids just to tear my soul apart piece by piece."
Queen Ayame closed her eyes, letting out a long, shuddering exhale that misted slightly in the crisp morning air. She hugged little Aria closer against her chest, her knuckles pale.
"I know it is cruel to say of one's own child..." Ayame whispered, her voice choked with a quiet, tragic grief as she tilted her head upward toward the vast, vaulted ceiling of the grand portico. "...but Lucian... you are walking down such a dark, twisted path."
High above them, hidden deep within the spatial distortions of the high rafters—unseen by mortal eyes—a pale, elegant figure leaned casually against a marble pillar.
Lucian Ariston looked down at his mother. A faint, mocking, yet inexplicably distant smirk touched his lips. Raising two slender fingers to his temple, he offered a silent, mocking salute, his lips moving without a sound in perfect imitation of Kairo's parting words:
Bye-bye.
Down on the terrace, Ariston's eyes snapped upward, his spatial senses flaring like a struck flint. The air above them rippled, leaving only cold, drifting particles of blue mana in the empty space.
"So..." Ariston gritted his teeth, his voice dropping into a dangerous, lethal register. "He is watching our every single move."
Queen Ayame looked up at the empty ceiling, her expression darkening with a cold, tragic certainty.
"Even if he weren't watching us directly..." Ayame said softly, her voice carrying the absolute horror of a mother who understood the monster she had raised, "...he would still outmaneuver and beat us through his sheer, terrifying intellect."
The dappled shade of the royal garden's ancient oak offered a cool sanctuary, though the quiet felt unnaturally heavy. Sitting with his back against the rough, moss-dampened bark, Kairo leaned his head against the trunk and let out a long, bored exhalation. A soft, fluttering rumble escaped his lips—the idle sound of a boy trapped in paradise with nothing to do.
His adoptive parents had firmly shot down his request to attend a proper academy. The official reason was his fragile health, a delicate cover story for a body that had survived horrors no child should ever know.
"Well," Kairo murmured into the stillness, watching a line of black ants transport a dead beetle across a root. "It's been peaceful for a while. I'm almost thirteen."
With a flick of his wrist, he summoned his system interface. A leather-bound tome materialized in a dim flash of gold light, hovering inches above his lap. The parchment pages flipped automatically, settling on a single line of crisp, ink-black text:
