When the apocalypse struck, the world as people knew it disappeared within days. Cities emptied, streets became dangerous, and fear became the new normal. The infected roam freely, and human survivors must choose between helping one another or betraying each other. Some groups try to rebuild a form of society, while others exploit the law of the strongest. Resources are scarce, and the roads are full of dangers, making every journey uncertain and every encounter potentially deadly.
After surviving a massacre at just two years old in an unidentified public place, Y/N is found alone, with no trace of her parents and no clear record of who she was or where she came from. Isaac, a man operating off the grid, takes her in after confirming that her family did not survive the incident. Instead of offering her a normal childhood, he raises her in a hidden training complex deep within the forest a fortified bunker disguised beneath dense woodland, equipped for surveillance, combat training, infiltration work, and intelligence gathering.
n is a foreign girl who was taken prisoner during a violent conflict and brought to feudal Japan, a world she does not understand and cannot escape. Instead of being discarded or executed, she is taken in under the protection of the Emperor, who keeps her under his roof as an unusual presence within the palace—neither servant nor guest, but something undefined. In a court ruled by silence, hierarchy, and power, her existence becomes an anomaly. Meanwhile, the Emperor’s most feared samurai, Ren Kuroda, is frequently assigned to missions outside the palace, which means Y/n only rarely crosses paths with him. Yet every encounter carries an unspoken tension that slowly begins to shift the balance of observation into something far more dangerous.
