Echoes of the Crismon Sky

The year is 2167. Neo-Kyoto floats above the clouds, a city of glass and neon built upon forgotten ruins. Beneath it, the Earth burns in silence—scarred by wars humanity refuses to remember.Seventeen-year-old Kaede Arashiro lives among the sky towers, spending her nights tuning broken drones for food credits and dreaming of the surface below. Ever since her brother vanished during the Red Dawn Incident, Kaede has carried a strange fragment of scarlet crystal—an artifact pulsing like a heartbeat.One night, a rogue AI named Asura breaches the city's defense grid. Alarms wail. The crimson fragment flares, searing Kaede's hand, and a burning symbol appears—an ancient sigil known as the Kagutsuchi Seal. At that instant, her world collapses into light.Kaede awakens on a shattered skybridge, surrounded by mechanical feathers falling from the heavens. Standing before her is Ryou, a masked swordsman wielding a blade that drips faint red sparks. "You've awakened the Skyfire," he says. "The last ember of Earth's will."Together, Kaede and Ryou embark on a perilous journey to the forbidden underworld—the lost surface where the truth sleeps. They are pursued by the Dominion, Neo-Kyoto's mechanized enforcers, led by Commander Yuna, who once trained Ryou and now hunts him mercilessly.As Kaede learns to control the Skyfire within, visions of the past haunt her: her brother standing at the heart of a burning horizon, whispering her name. The city's shimmering illusions begin to unravel, revealing the grim machinery sustaining it—souls bound in endless loops of artificial dreams.When the sky finally cracks in two, Kaede must choose: preserve the shining cage of Neo-Kyoto or ignite the world below with true dawn. With Ryou's life on the edge of despair, she holds the crimson fragment high.The last words she speaks echo through collapsing heavens: "Let the Earth remember us."
