The bell of Fiester Academy did not ring.

  It hummed.

  A low, resonant vibration rolled through the ancient stone halls, slipping beneath doors, climbing pillars, settling into bone. It was not loud—but it was unmistakable. Every third-year student felt it at the same moment, like a hand placed firmly on the spine.

  A summons.

  Aerin Solace stopped mid-step in the eastern cloister, fingers tightening around the strap of her satchel.

  “…That tone,” she murmured. “They’ve never used that one before.”

  Nearby, Valtor Quinn exhaled slowly, as if he’d been expecting this for years.

  “So,” he said, voice steady, “they’ve finally decided.”

  Students began pouring from corridors, training halls, dormitory wings. Forty names—though no one knew the count yet—gravitated toward the same destination without being told where to go.

  The Crownreach Plateau lay beyond the academy walls, a natural stone rise overlooking the Fiester Kingdom’s inner valley. It was a ceremonial ground, older than the academy itself, carved with concentric sigils meant for declarations of war and oaths of succession.

  No one had seen it active in decades.

  Now, as the third-years arrived, the air above the plateau folded.

  Light bent inward, forming two massive vertical ovals—portals—suspended several feet above the ground. One glowed a restrained silver-white. The other… darker. Not black, but deep obsidian threaded with faint violet lines, like veins beneath skin.

  A hush fell.

  Ren Falk stared upward, jaw tight.

  “Two gates,” he said quietly. “So the rumors were true.”

  Felix Crowe grinned beside him, flipping a card between his fingers.

  “Please tell me this is the fun kind of illegal.”

  “No,” Ryozen Kaoru replied flatly. “It’s the permanent-record kind.”

  At the center of the plateau stood a single figure.

  Itsuki Shiraishi.

  The Headmaster of Fiester Academy looked smaller than usual, wrapped in layered ceremonial robes that threatened to swallow her frail frame. Her back was slightly bent. Her hands trembled faintly as they rested on a cane carved with old knightly runes.

  But when she lifted her head—

  The air stilled.

  Every student straightened as if struck by instinct.

  Itsuki’s voice, when it came, was thin—but absolute.

  “Third-year students of Fiester Academy,” she said. “You stand here today not as children, nor as soldiers… but as variables.”

  A ripple of unease passed through the group.

  Valtor stepped forward half a pace. “Headmaster,” he said respectfully, “with due clarity—what is this assembly?”

  Itsuki’s eyes found him instantly.

  “Command,” she replied. “And consequence.”

  She raised her cane. The sigils beneath the portals ignited, lines crawling outward like living things.

  “This,” she said, “is the Island Conflict Protocol.”

  Someone inhaled sharply.

  Someone else whispered, “The Death Game…”

  Itsuki did not deny it.

  She gestured—and the air shifted. A projection unfolded above the plateau, letters of light burning into visibility.

  THE ISLAND CONFLICT PROTOCOL

  Itsuki spoke as the rules appeared, each section locking itself into place like a verdict.

  “I. Participants. Only third-year students from two registered academies may participate. Each school deploys exactly forty students.”

  Murmurs. Heads turning. Counting.

  “You will be transported to opposite shores of the island,” Itsuki continued, “and released simultaneously. There will be no teachers. No referees. No visible supervisors.”

  Hoshino Rei clenched her fists.

  “No supervision?” she snapped. “Then who stops it from—”

  “The system,” Itsuki interrupted. “And your restraint.”

  She tapped the cane once.

  “II. Objective. Eliminate the opposing school by forcing all enemy students into incapacitated status.”

  Aerin’s breath caught. “Eliminate…?”

  “A student is considered eliminated,” Itsuki said evenly, “when they lose consciousness for more than ten seconds, verbally declare surrender, or their core vitals fall below safe combat thresholds.”

  You might be reading a stolen copy. Visit Royal Road for the authentic version.

  Felix whistled softly.

  “Bloodless,” he said. “In theory.”

  “Killing techniques,” Itsuki added, eyes narrowing, “are allowed in form only. Execution-level force will be suppressed.”

  Several students shifted uncomfortably.

  “III. Combat Authorization. All martial arts, swordsmanship, and combat techniques are permitted. Environmental weapons are legal.”

  Ryozen’s hand moved instinctively to the hilt of her katana.

  “IV. Weapons & Equipment. Standard-issue training weapons will be provided. Customized weapons are allowed only if inspected and embedded with non-lethal limiters.”

  Felix raised a hand. “Cards?”

  “If approved,” Itsuki said without looking at him.

  Felix smiled wider.

  “Firearms, explosives, poisons, and long-range weaponry are prohibited.”

  Ren nodded grimly.

  “V. Injury & Safety Control. You will wear suppression seals.”

  At that, metallic bands floated up from the sigils and snapped around each student’s wrist or neck with a soft click. Cold spread through skin.

  “These seals prevent fatal trauma,” Itsuki continued. “They do not suppress pain.”

  A hush.

  “Broken bones, bleeding, and extreme exhaustion are expected.”

  Someone swallowed audibly.

  “VI. Elimination & Extraction. Eliminated students will be paralyzed and extracted by unseen retrieval units.”

  Aerin frowned. “Unseen…?”

  “Extraction leaves no visible trace,” Itsuki said. “Disappearance is intentional.”

  Fear crept in now. Real, slow fear.

  “VII. Territory & Movement. The entire island is a free-combat zone. Leaving it results in immediate elimination.”

  “VIII. Alliances & Betrayal. Alliances within your school are allowed. Cross-school alliances are forbidden.”

  Felix tilted his head. “And betrayal?”

  Itsuki’s gaze sharpened.

  “Permitted. Remembered.”

  That landed harder than any threat.

  “IX. Time Limit. Seventy-two hours. Sudden Death activates in the final hour.”

  “And finally,” Itsuki said softly, “X. Victory & Consequences.”

  The projection dimmed, leaving only her voice.

  “The winning school gains prestige. Resources. Priority.”

  She looked at each of them in turn.

  “Your individual performance will be recorded permanently.”

  Silence.

  “Cowardice,” she added, “recklessness, and betrayal… are all documented.”

  Valtor bowed his head slightly.

  “So this is not an exam,” he said. “It’s a verdict.”

  Itsuki smiled faintly.

  “No,” she said. “It’s a mirror.”

  The darker portal pulsed.

  “Your opponents,” Itsuki continued, “are the third-years of Obsidian Vale Academy.”

  At that moment, the obsidian gate opened wider.

  For an instant—just an instant—the Fiester students glimpsed the other side.

  Rows of figures stood beneath a darker sky. Still. Watching.

  At their front stood a tall woman with silver-black hair and an elegant posture.

  Elira Vayne.

  Her lips curved, not quite into a smile.

  Aerin felt a chill crawl up her spine.

  “They’re not afraid,” she whispered.

  “No,” Ren replied. “They’re ready.”

  Itsuki Shiraishi lifted her cane one final time.

  “There are no deaths here,” she said. “Only survivors who return… changed.”

  The silver-white portal flared.

  “Fiester Academy,” Itsuki commanded, “step forward.”

  One by one, the forty students moved.

  Some hesitated.

  Some smiled.

  Some clenched their teeth and said nothing.

  As Aerin crossed the threshold, light swallowed her—and for a split second, she felt something flicker against her suppression seal. A flaw. A whisper of instability.

  Then the world inverted.

  Two portals closed.

  Two shores awaited.

  And the Island Conflict Protocol began.
