Shoujo Kesshou Cocological

In the near-future of Year 20xx, society has evolved into a high-tech civilization where individuals are classified according to their birthstone. At the heart of this world lie two defining pillars: "BOX," a colossal virtual reality system that stores and manages the data of the global population, and "Logiste," a high-stakes dance competition—both fierce and perilous—whose victors are celebrated as genuine celebrities. For young Kokoro Koyomi, however, this world remains entirely out of reach, as her overbearing father strictly forbids her from even mentioning it. One day, she seizes the opportunity to secretly log into BOX, but a system bug traps her inside the virtual realm, leaving her stranded with no way out.
