Kaiba unfolds in a distant future where memories can be stored, traded, and transplanted like commodities, making physical death no longer the end of a person’s existence. In this fractured world, the wealthy buy new bodies and extend their lives, while people in the lower world are often forced to sell their own bodies just to survive beneath an artificial cloud that divides the privileged skies from the miserable surface below.
When Kaiba awakens in an empty room with no memories, a hole in his chest, and a locket containing the image of an unknown woman, he is thrown into a journey across planets and ruined settlements in search of his identity. As fragments of a life he cannot remember begin to surface, Kaiba’s path gradually becomes less about recovery than about understanding the value of memory, desire, and the self. Along the way, the series follows his pursuit of the woman in the locket and the bonds, losses, and contradictions that define his past. Kaiba turns that quest into an intimate science-fiction fable about love, loss, and what it means to remain human when memory can be separated from the body.
