[ Vol.3 ] Lucius “Lucien” Cronus—a titan of time, innovation, and power—stands at the peak of a world he reshaped with genius time-fueled ambition. Yet every triumph is hollow, every bond an echo—because none can replace those he’s truly lost. When faint disturbances ripple through time, Lucien’s obsession reignites, pulling him toward a confrontation no invention can stop—and a fate no one can escape.[ Vol.1 ] Ren, a young clockmaker’s apprentice living in 1868 Japan, begins to experience strange visions—glimpses of people he’s never met and lives he’s never lived. When a girl from an elite family speaks words he’s only heard in dreams, Ren is pulled into a mystery that stretches beyond memory and time. As dangerous spirits appear and reality begins to shift, he must uncover the truth behind his visions before everything he knows begins to slip away.
