The Age of Colossi

A century after the Nanite Event, humanity battles Colossi from dimensional rifts. Will you live, fight, or emerge as one?

Plot

AN ORIGINAL SCI-FI ANIME ADVENTURE THE AGE OF COLOSSI HUMANITY EVOLVED. THE RIFTS REMAIN. 01 / THE BEGINNING A World That Refused to Die. Over a century ago, humanity nearly vanished. From a catastrophic rupture in space emerged a monstrous entity remembered as The First Colossi. Its rampage devastated civilization, leaving the world on the brink of extinction. But from its wounded, shedding body came something extraordinary: Nanites. These microscopic machines spread throughout the world, eventually becoming part of humanity itself. Today, every human is born with nanites flowing through their bloodstream. With enough talent, training, and imagination, they can assemble magnificent weapons, armor, mechanical limbs, and towering constructs. HUMANITY'S GREATEST WEAPON A novice may create a simple blade. A master may wield a mechanical fist large enough to strike a giant. Yet beneath every construct remains a vulnerable human body. And the creatures never stopped coming. Across the world, dimensional rifts continue to tear through reality, announcing the arrival of terrifying beings known as Colossi. Some resemble enormous animals. Others possess humanoid forms, impossible anatomy, or bodies of living metal, crystal, stone, and stranger materials. Humanity's defenders, the Vanguard, stand ready to confront them. But your place in this world is yours to decide. 02 / YOUR STORY Three Paths. One World. 01 — CIVILIAN Live an ordinary life in an extraordinary age. Discover your nanite potential, form relationships, explore the world, and choose your own future. 02 — VANGUARD Join humanity's frontline defenders. Stand beside fellow nanite wielders, confront Colossi, and experience the responsibility of protecting civilization. 03 — COLOSSI Enter the world as an actual Colossus. Define your own form, abilities, intelligence, and intentions. Humanity fears your kind. What you become is up to you. NO CHOSEN ONE. NO FIXED DESTINY. Survive. Protect. Explore. Conquer. Coexist. THIS IS YOUR AGE OF COLOSSI. PUBLIC INFORMATION DATABASE WORLD FIELD GUIDE Essential knowledge for life in the Nanite Era 01 / NANITES Microscopic, self-replicating machines inherited by every modern human. They reproduce and assemble into physical constructs according to their wielder's imagination, training, and skill. Uses: Weapons, armor, tools, mechanical limbs, transportation, construction, and colossal-scale machinery. Weaknesses: Severe construct damage depletes nanite reserves. Even powerful wielders remain mortal. 02 / COLOSSI Extradimensional beings of extraordinary size and diversity. They may resemble beasts, insects, humanoid giants, or organisms with almost unimaginable anatomy. Their bodies can be biological, metallic, crystalline, mineral, exotic, or a mixture of several substances. Some are instinctive. Others demonstrate remarkable intelligence. Most encounters are dangerous, though no single behavior defines every Colossus. 03 / SPATIAL RIFTS Catastrophic tears in reality that connect Earth to the realm beyond. Every opening releases additional nanites, and Colossi may emerge through the rupture. A typical Rift Event destroys everything within a radius roughly equivalent to five football fields. Modern seismic detection networks provide advance warnings, but no warning system can guarantee safety. 04 / THE VANGUARD Humanity's organized defense against Colossi incursions. Vanguard personnel use their own nanite constructs, military coordination, scientific intelligence, and specialized equipment to protect civilian populations. Because Colossi are usually dangerous, unidentified arrivals are treated as threats until sufficient evidence suggests otherwise. HISTORICAL ARCHIVE The First Colossi THE ORIGINAL CATASTROPHE · 100+ YEARS AGO A single entity known as The First Colossi nearly destroyed human civilization. During its rampage, nanites released from its body spread throughout the world, beginning the Nanite Era. The entity eventually vanished back beyond the rift. Much of its history remains a mystery. PRIMARY STORY REGION East Asia Experience a rebuilt civilization across Japan, South Korea, China, and Taiwan. Each region preserves its own history, culture, and daily life while adapting to the threat of Rift Events. JAPAN · SOUTH KOREA · CHINA · TAIWAN THE PEOPLE OF THIS WORLD Who Will You Encounter? Civilians Students, workers, families, merchants, and everyday people living their own lives in a nanite-integrated society. Vanguard Personnel Soldiers, officers, scouts, rescue specialists, and commanders with diverse personalities and unique nanite constructs. Researchers Scientists, engineers, physicians, and investigators studying nanites, Rift Events, and extraordinary lifeforms. Colossi Unpredictable extradimensional individuals whose biology, intelligence, behavior, and capabilities differ enormously. EVERY ENCOUNTER HAS A STORY.
