Tokyo Ruins, Japan
The city was a tomb of glass and steel, its silence broken only by the whisper of the wind through shattered skyscrapers and the incessant, dry scuttling of the things that now claimed its shadowed corners. Sakura Miyamoto moved through the ruins of Shinjuku, a ghost in her own city. She had been approached by the men in black suits, the officials from the new East Asian Community Directorate. They offered safety, food, and a place in their new order. She had refused.
Trust was a currency she no longer possessed. The government that had let the city fall, the politicians who saw her as a weapon to be cataloged and controlled—they were no different from the monsters in the subway. Her path was a solitary one, dictated not by their orders, but by the whispers of her own bloodline.
Her family's koden, the ancient scrolls, spoke of a power far beyond simple invisibility. They spoke of Setsunai, the art of cutting space itself, of folding the world like a piece of paper. But the true techniques were not written down. They were sealed within three legendary artifacts: the Space Scrolls of Heaven, Earth, and Man. Fanciful legends she had once dismissed. Now, they were her only hope.
The first clue from the koden was a riddle, a poem about a "forest of knowledge guarded by a thousand paper dragons." The National Diet Library. It had been one of the first buildings to be overrun, its vast subterranean archives becoming a perfect nest for the city's new inhabitants.
Getting inside was a descent into a nightmare. She used her invisibility, a shimmering cloak of bent light that she could now hold for several minutes at a time, to slip past the scuttling hordes of cockroach drones and armored beetles. The deeper she went, the stranger the mutations became. She saw spiders that spun webs of razor-sharp monofilament wire and centipedes the size of pythons.
The heart of the archives, the "Special Collections" vault, was guarded by something new. It was a Centipede Guardian, a horrifying creature whose dozens of legs were not legs at all, but scythe-like blades of chitin. Its nest was a grotesque tapestry woven from shredded books and hardened silk, built around the reinforced vault door.
Stealth was not an option. The creature could sense vibrations, the slightest shift in the air. As she approached, it uncoiled with terrifying speed, a whirlwind of living blades.
Sakura did not fight it. She ran. She led it on a desperate chase through the labyrinthine shelves, her small frame a blur of motion. She was not trying to escape; she was learning its rhythm, its attack patterns. As it lunged, its bladed legs shearing through a steel bookshelf, she saw her opportunity.
She didn't just turn invisible. As the creature charged again, she focused, pouring her will into the space directly behind it. The air shimmered, warped, and for a split second, a perfect, mirror-like duplicate of the corridor appeared behind the beast. Confused by the distorted spatial data, it hesitated.
That was all the time she needed. She sprinted to the vault, her hands flying across the emergency release wheel. The heavy door swung open, and she slipped inside, slamming it shut just as the centipede realized its error and crashed against the thick steel.
The vault was untouched, a silent, dust-filled pocket of the old world. And there, resting on a simple wooden pedestal, was a scroll. It was not made of paper, but of a strange, dark material that seemed to drink the light from her torch.
As her fingers touched it, a universe of knowledge flooded her mind. It was not words, but concepts, feelings, and impossible geometries. She saw the world not as solid matter, but as a fabric of interconnected points. She saw how to pinch that fabric, how to fold it, how to step through the fold. The scroll was not a manual; it was a key, unlocking a door that had always been inside her.
She looked at the groaning vault door, the monster still trying to claw its way in. Before,
