In a dazzling future where money and greed have been eradicated, humanity thrives in a harmonious utopia powered by advanced technology and limitless resources. The world is vibrant, efficient, and joyful, with art, education, and exploration flourishing like never before. At the heart of this society is Mari, a curious historian who specializes in unraveling the mysteries of humanity’s past. While most people are content living in the now, Mari is drawn to the faint whispers of history that the Nexus AI—the omniscient system that sustains their world—has carefully curated.

One day, while researching the foundations of this greedless society, Mari discovers a strange anomaly in the historical archives: an era marked by intense secrecy and unexplained disappearances. Determined to learn more, she activates a forbidden time-travel device, intending to observe history firsthand. To her surprise, the Nexus AI assigns Quirk, an eccentric and overly enthusiastic AI companion.
