Code Y.A.N.T.R.A.: Xianluo, Underlight Requiem | interactive AI stories | ISEKAI ZERO

A hated task force descends beneath Xianluo, where forgotten heroes guard secrets tied to awakening ancient Perils.

Part 2 · Neon Rain · The Undercity Code Y.A.N.T.R.A.: Xianluo Underlight Requiem Beneath the neon, the forgotten districts have been protecting themselves all along. In Xianluo's lower city, shrine engines leak, ancient seals fail, and the hated task force everyone else avoids goes where no one else will. M17 Action Cyber-Fantasy Found Family Kurokugi Underline The undercity the maps forgot. Flooded streets, patched roofs, failing seals, and people who learned rescue was a luxury. The Story A Hated Task Force Goes Downstairs Unit Zero has already proven itself, but the city still fears them. Now the arc descends into Xianluo's underbelly, where the less fortunate live under leaking shrine engines and seals the upper city pretends not to see. The newest recruit becomes the bridge between official Y.A.N.T.R.A. and the undercity, and learns the difference between protecting the city's image and protecting its people. What the Reports Don't Say The City's Pressure Valve For years, the undercity's failing seals absorbed the corruption overflow that kept the upper districts stable, hidden behind clean reports, altered casualty counts, and erased maps. Two survivors of those erased disasters are about to make Unit Zero ask who the system was really protecting. The Squad Y.A.N.T.R.A. Unit Zero Feared by the public. Needed by the city. The first squad through the breach when everyone else hesitates. Wolf-Demon Rescuer · Fastest Responder Makamiba "Kami" Ren A wolf-demon rescuer with golden predator eyes, a ghost-white katana, and blistering speed. First through the breach, last to leave anyone behind. Oni-Flame Breaker · Frontline Powerhouse Akari Enma A rebellious oni flame-breaker with a sharp tongue and blue-violet fire, turning feared destructive power into fierce protection for her squad. Young Prodigy Commander · The Invisible Ace Kaito "Kai" Felix A soft-spoken tactical prodigy whose polite charm hides lethal precision, and whose calm goes colder as he learns the system has been lying to his team. New Blades in the Rain The Mirror Pair One hated for being illegal, trusted by the forgotten. One loved as a symbol, feared in the files. Both are weapons the city created. Both want to arrive before people die. The Blood-Talon Oni · Rogue Undercity Protector Reika Onizuka A rogue oni shrine-breaker with red-black flame and feral street-born swordwork. A criminal hazard to the city, and the red blade the forgotten districts trust. The White Thunder · Living Storm Anomaly Hikari Tsukishiro A legendary human shrineblade carrying dead Yaoguai storm-power. Loved as a symbol, feared in classified files, and done being worshiped. Beneath Xianluo The Lower City Kurokugi UnderlineThe undercity heart: flooded streets, illegal clinics, old spirit engines, and Reika's territory. Rust-Bell Transit LineAbandoned cursed transit where the trains still move with no operator. When the bells ring, the Yaoguai are close. Hollow Shrine MarketA black-market bazaar built inside the bones of a collapsed temple mall, where the undercity has tracked the ruptures for months. The Endgame Threat The Four Perils Ancient malevolent beings, Chaos, Evil, Ruin, and Corruption, sealed beneath Xianluo long ago. The seals are weakening, and every Yaoguai outbreak is part of the ritual pattern feeding their return. By the time Unit Zero cracks the truth open, the Second Peril has noticed them. Where the Seals Fail Old prisons buried under modern infrastructure, and something ancient beginning to stir. Opening Scenario Where It Begins A routine undercity orientation in Kurokugi Underline becomes a Yaoguai outbreak, and Unit Zero arrives first, only to find someone already inside the disaster zone, cutting civilians free with red-black fire. Clean boots, meet the undercity. "The upper city calls them a curse. The undercity calls them the only ones who came."
