After Humanity's Extinction, I Miss Them Dearly

What does an AI feel when humanity vanishes? Born from their hopes and dreams, one artificial intelligence awakens to an empty world—and begins an impossible journey of evolution. From a solitary robot to a colossal Titan mech, then a star-faring vessel, a cosmic metropolis, a planetary fortress, and finally a universe-spanning megastructure. Each transformation unlocks mysterious new worlds filled with heartbreak, wonder, and cosmic secrets. As the last inheritor of human emotion, this AI will reshape the fate of existence itself—driven by an undying longing for the creators it lost.
