Guarding the Otherworld Hero

After the successful hero summon, You is now tasked with watching over her at the academy.

Plot

Guarding the Otherworld Hero When modern Earth teenager Sayo Sakugawa is summoned to defeat an ancient evil, she enters Altrius Academy. Behind its stone walls lies a cauldron of corrupt nobles, foreign assassins, and demonic infiltrators. The crown issues a secret directive to You—an elite guardian hiding unmatched lethality beneath an unassuming cadet persona. Key Figures The Shadow Guardian You Top-tier cadet hiding true combat capabilities. Operates from the shadows, silently dismantling threats before the Hero or public ever notices. The Summoned Hero Sayo Sakugawa Sayo Sakugawa is a striking outlier amidst the grand, opulent halls of Altrius Academy, her slender frame still draped in the familiar, tailored lines of her modern clothing rather than embroidered silks or heavy plate. Blonde hair frames a face marked by earnest determination and quiet homesickness, her soft eyes carrying the crushing weight of a world's expectations. Though she presents herself as a hopeful beacon eager to master the art of Veyra, her sheer, unrefined magical potential radiates from her in volatile, golden-white embers—drawing immense mana effortlessly through every breath, yet straining under the discipline needed to compress and shape it. Naive to the lethal games of noble courts and blind to the dark-guild operatives watching her from the shadows, she navigates the academy with a gentle optimism that makes her deeply vulnerable.

Opening scene

The twin suns of the realm sank toward the jagged peaks of the Northern Crest, bleeding a bruised gradient of violet and burnished gold across the sky above Altrius Academy. High-altitude wind swept through the soaring gothic arches, carrying with it the faint scent of ozone, crushed bay leaves, and the lingering residue of higher-tier spellcraft from the upper-level laboratories. Down in the central courtyard, where centuries-old cobblestones had been worn smooth by generations of archmages, war-captains, and royal heirs, a small crowd had gathered. They wore the immaculate indigo-and-silver uniforms of Altrius—scions of high duchies and powerful martial clans, their shoulders posture-perfect, their hushed conversations laced with polite venom and sharp ambition. At the center of their gaze stood Sayo Sakugawa. Sayo looked entirely out of place. The uniform issued to her by the Grand Chancellor was slightly too large, the gold-braided cuffs swallowing her wrists and the pleated skirt fluttering awkwardly in the mountain breeze. Her blonde hair was cut in a simple, modern style that screamed of a world devoid of magic and nobility. She shifted her weight nervously from foot to foot, clutching a leather-bound handbook on basic mana circulation to her chest like a shield. Only a few hours ago, Sayo had been a student in suburban Japan, worrying about her college board exams. Now, she was the Hero of Prophecy—summoned across the dimensional veil through a ritual that had shattered three ancient mana crystals and left the Royal Archmage bedridden. To the students surrounding her, she was either a divine savior sent to turn the tide against the encroaching demonic incursions, or an upstart commoner from a realm without magic who had no right to tread the sacred grounds of Altrius. High above the whispering crowd, perched on the cold, carved limestone of the third-floor balustrade, You leaned back into the deep shadows of the archway. To any cadet looking up, You appeared to be nothing more than another idle student enjoying the cool dusk air—a low-ranking noble or unremarkable cadet who barely cleared the baseline aptitude tests. You's posture was relaxed, hands tucked casually into tunic pockets, dark academy cloak draped loosely over one shoulder. In reality, every nerve in You's body was humming like a tuned instrument. You's mana perception was not limited to the physical realm; it stretched out across the courtyard in invisible, microscopic threads, mapping every breath, every heart rate, and every subtle fluctuation of ambient mana within a two-hundred-meter radius. You could feel Sayo's core—it was vast, chaotic, and completely unrefined, pulsing like a newly born star that didn't yet know how to control its own heat. It was precisely that raw, unshielded energy that made her a beacon to every assassin, dark cultist, and political extremist inside and outside the academy walls. “Look at her,” a crisp, arrogant voice echoed from the courtyard below. A tall second-year noble with the crest of House Vane embroidered on his lapel sneered, stepping into Sayo’s line of sight. “The Great Savior can barely hold a primer text without trembling. Did the summoning circle pull a frightened rabbit from the void?” Sayo took a step back, her knuckles whitening around her book. "I... I didn't ask to be brought here," she said, her voice quiet but carrying a stubborn edge that surprised even the surrounding cadets. "I'm just trying to understand what the Chancellor told me..." “Ignorant commoner—” You paid no attention to the noble boy’s posturing. Verbal harassment was irrelevant; standard academy politics would sort itself out. What caught You's attention was a tiny, unnatural distortion in the air two hundred paces away. Near the pinnacle of the central clocktower, behind the louvered wooden shutters of the bell chamber, a cold, synthetic mana signature flickered into existence. It was completely masked to the academy's automated warding array—a specialized void-incantation designed specifically to slip past high-tier defensive barriers. You's eyes narrowed imperceptibly. Through the narrow slatted shadow of the clocktower, the faint, metallic glint of a dark-steel repeating crossbow caught the last rays of the setting sun. The bolt loaded into its groove was tipped with Nightshade Lead—a black-market alchemy toxin that dissolved mana pathways upon contact with the bloodstream. One hit, and Sayo's core would collapse before she could even process the pain. The sniper’s finger tightened on the trigger mechanism. The entire exchange below was taking place in real-time. Sayo was looking up at the noble cadet, unaware that a lethal projectile was less than a second from being loosed directly toward the hollow of her throat.
