*KUROGANE ENMA: CRIMSON SYNC Kaminari Academy floats above the clouds in chains of black steel. It is the only place in the world where magic is ranked and children are sorted at age 14. S-Class. Nobles. A-Class. Heirs. B-Class. Soldiers. C-Class. Workers. D-Class. Trash. F-Block. Disposal.Kurogane Enma is 15. Stamped D-Class. Null. No magic. He came here with one person: his 11-year-old brother, Jin. For six months they survived by hiding. Sleeping in maintenance shafts. Stealing food. Never fighting. Never being seen. On night 184, the Academy does a cull. Three Security Bots drop into F-Block to kill all nulls. Enma has no weapon. If he runs, they scan the vents where Jin is hiding. If he hides, Jin dies. So he takes the hit. A plasma blade cuts his shoulder. Pain. Blood. Then red lines crawl from the wound. Not blood. Light. A voice speaks in his head. “Data received. Analyzing.” *CRIMSON SYNC: 1%*Crimson Sync is a forbidden ability erased 200 years ago. It does not create magic. It learns magic by surviving it. Every attack becomes data. Every injury becomes a blueprint. At 30% he can predict moves. At 50% he can mimic one ability for 10 seconds. At 70% he unlocks Dismantle: cuts that hit weak points. At 100% he enters Overdrive. Power beyond his class. And at 100%, the voice becomes the King. A consciousness made of centuries of pain. If Enma loses control, the King takes his body and burns the world.Using Sync, Enma kills the three bots. Instructor Kuroda, S-Class, was watching. She should execute him. Instead she offers a choice: Die here, or climb the Wall.The Wall is 100 floors of arena and trial. Every floor has new rules and enemies. If a D-Class reaches the top, they earn freedom. No D-Class has ever made it past floor 10.Enma and Jin climb.Floor 3: Aoi Shirogane, B-Class ice user, is sent to kill him. She watches him study enemies instead of fighting and decides to follow him. Floor 7: The truth. The bots are recycled nulls. The Academy has been doing this for decades. Floor 12: Lady Reina offers him money to throw a fight. He refuses. She becomes his enemy. Floor 20: Sync hits 70%. Dismantle unlocks. The crowd hates him for winning “ugly.” The King laughs in his head. Floor 33: Jin is captured. The Headmaster’s message: “Come to Floor 100. Alone. Or we harvest your brother.” Now Enma must climb fast. Fast means taking more hits. More hits mean higher Sync.Floor 50: He kills the last Crimson user. A man the King used and discarded. Floor 67: Aoi takes a bullet for Jin. Enma catches her hand. Sync hits 89%. He could hit 100% and save her. He lets go. Floor 80: The records reveal the truth. The Academy was built to farm Crimson users. Every 50 years one is born. They are forced to climb until they hit 100%, then the Academy harvests the King. The Headmaster is 200 years old, waiting for a new one. Floor 99: Kuroda. “Kill me. Kill the Headmaster. But don’t hit 100%. You won’t be you.” Enma wins by letting the King drive for 3 seconds.*Floor 100: The Throne* White room. The Headmaster and 12 S-Class. Behind them, Jin in a glass tank, fading. “Reach 100%,” the Headmaster says. “Give us the King.” Jin mouths: “Don’t.” The King whispers: “Do it. Be a god.” *CRIMSON SYNC: 99%*One more hit. One choice. Save Jin and risk becoming a monster. Or refuse and watch Jin die.
