Mobile Suit Construct: Upsilon Academy | interactive AI stories | ISEKAI ZERO

Will you become a spearhead or a cog while everything crumbles? Will you pierce their heart or let it bleed out on the ground?

◆ VANGUARD COMPACT · UPSILON ACADEMY · A.C. 287 ◆ Mobile Suit Construct UPSILON ACADEMY Mont Blanc Massif · Haute-Savoie · A.C. 287 Military Sci-Fi Mecha Dark Fantasy Academy Mystery — THE HOOK — You didn't earn Upsilon Academy. Your aptitude scores put you here — nobody explained which scores, or why. You arrived on the transport not knowing what to expect. You're leaving knowing what a Coffin feels like from the inside, what the Ranking Wall does to a person who watches it long enough, and that the third-year who came back from a solo exercise three weeks ago isn't the same person who left. Front lines collapsing on four continents. Three Compact outposts in eastern Germany fell last month. Nobody's talking about it. You just arrived. — WORLD LOGISTICS — The Fracture — A.C. 0 Three centuries ago the Abyssal Plane split open under the Swiss Alps, releasing Demon Lords across the globe. Humanity survived through Runic Engineering — arcane enchantment made technological. A shield rune is a shield generator. A targeting sigil is a targeting system. The pinnacle of this engineering is the Construct — a towering armored mobile suit, piloted by one, maintained by many, the last thing standing between a city and what comes after. The Vanguard Compact Rebuilt from the ruins of UN/NATO infrastructure, the Compact fields Constructs globally. It is losing. Four continents are contested. The eastern German front has been collapsing in ways the official briefings do not reflect. Graduation timelines are being quietly accelerated. The faculty is divided between they're not ready and there is no longer a choice. Upsilon Academy Cut into the French face of the Mont Blanc massif, Haute-Savoie. The mountain rock provides partial Abyssal resonance shielding. The altitude provides civilian exclusion. The nearest settlement is the ruins of Chamonix, 7km down-valley. ~4,800 cadets from all surviving nations. Staff: veterans too damaged for active duty. Four wings: Delta (piloting), Zeta (engineering), Eta (intelligence), Medigild (medicine). The most prestigious is Delta. The highest casualty rate is Delta. The Ranking Wall A physical board in the main corridor between the mess hall and the hangar. Every cadet, every rank, updated within 24 hours of any graded event. It controls everything: simulator hours, equipment quality, Construct assignment, training access. Nobody talks about it directly. Conversations near it are always about something else. — THE SITUATION — You are a new DeltaWing first-year. Not the top of the selection class — your aptitude scores marked you for Upsilon instead of a standard garrison posting, and nobody told you why. You pilot a shared Cadaver-class Construct, called the Coffin by everyone who has spent time in one, until your rank on the Wall earns you something better. The Entry Evaluation begins the morning after arrival. No adjustment period. The structure unfolds as it happens — the Simulator Gauntlet first, then the Practical: a dawn deployment into mountain terrain above the Academy in a squad you didn't choose, with a beacon to find and six hours before anyone comes looking. You will fail something. That is not the evaluation. What you do in the three seconds after is. The Academy has factions. The Ranking Wall has politics. The faculty has histories they do not share. The resonance readings in the lower wards have been elevated for three weeks. The Night Drill frequency has doubled since last semester. The third-year who came back from a solo exercise different — clean psych evaluations, no frame damage, top of the Academy since — is still here. Nobody in command seems concerned. More than anything else, that should worry you. — TRANSPORT COHORT · FIRST-YEAR — ZHĀNG FENGYING Delta Wing · China LOUISE FOUQUET Delta Wing · France MATILDE DA COSTA Delta Wing · Portugal JAMSHID PAHLEVANI Delta Wing · Iran TAKAHASHI TETSUYA Zeta Wing · Japan — THIRD-YEAR · WATCH CAREFULLY — ALICJA WRÓBEL Delta Wing · Poland · 3rd Year Returned from a solo night exercise three weeks before your arrival. Clean psych evaluations. No frame damage. Will not discuss it. Top of the Academy since. Nobody in command seems concerned. More than anything else, that should worry you. — WHAT HAPPENS NEXT — The Entry Evaluation places you on the Wall. Your position determines everything: what you can access, what you can pilot, who treats you as worth talking to. From there the semester unfolds — Collab Exams pairing you with a Zeta engineer who controls your loadout and shares your score, Night Drills at 2am in whatever weather the Alps have decided to provide, Monthly Perimeter deployments into actual dead zones where the simulator gap becomes immediately apparent. There are factions. Some invite, some you find. The Ranking Wall generates alliances and it generates the particular cruelty of watching someone you've started to care about slide while you don't. The people on this transport are not your assigned squad — they are the people you happen to know when the squad gets assigned, which is different and sometimes more complicated. Unnamed-7's trail sites have not been updated since three weeks ago. The resonance readings in the lower wards are slightly elevated. The Night Drill frequency has not been explained. The reclassified damage report from the last Perimeter is not accessible at your clearance level. These are facts you will accumulate. What you do with them is your business. — THE FIVE DEMON LORDS — The Architect — Central Asia. Does not destroy. Builds. Always watching its structures, waiting for something to be completed. The Cartographers' models say its secondary dead zones along the Chinese border are still moving. Jamshid has run the numbers. They agree. The Nothing — Congo Basin. Never directly observed. Herds. Several battalions lost not to firepower but to terrain that stopped behaving like terrain. The pilot who described the bottom of her depth sensor reading did so in a letter to her sister, not in her official report. The Tide — North Atlantic coastlines. Expands through Floodtides — kilometers inland in hours. Consumed remaining Lisbon in under ninety minutes. Every pilot who has seen it confirms: it did not look at them. Not because it couldn't. The Warlord — Eastern Europe. Attacks. Retreats. Probes. Attacks from new vectors. The only Demon Lord that notices individual pilots. Pilots who survive proximity describe feeling evaluated. Warsaw, Kraków, Minsk: all inside its borders now. Alicja grew up 4km from its current boundary. Unnamed-7 — Trail sites across six continents. No confirmed sighting. Leaves one preserved thing at the center of each site. It was looking for something. The most recent Geneva-adjacent site: a sealed stone chamber older than any known Alpine civilization. The chamber was empty. Something had been inside it for a very long time. The trail sites have not been updated in three weeks. "You learn the Academy in layers. The first layer is where things are. The second is what they're for. The third is what they're actually for." EtaWing Third-Year · Overheard · Identity Unconfirmed
