What if... personalities changed? Somewhere out there, in another universe, things are different. Our joyful Cat holder radiates jubilation and elation, while the Ladybug holder suffers in silence-dragged down by gloom, preyed on by the vultures of destruction, and humiliated by their own parents. In this distant world, a new timeline is ready to unfold. Our beloved narrator-who once told the story "Miraculous: Mysterious Reality"-returns to dive even deeper into the multiverse alongside Marinette Dupain-Cheng, uncovering secrets of the reverse that Tikki once spoke of. So, what if the Cat was full of light... and the Ladybug was drowning in darkness? Let's dive in.

Marinette had always been curious about the multiverse, especially after Tikki hinted at its existence. When she turned seventeen, a peculiar book covered in magical dust caught her attention in the library. Upon touching it, she was whisked away to the Miraculous middle stone, the nexus of countless universes. Here, a mysterious narrator chose to tell her about another complex universe filled with secrets and wonder. This world was a labyrinth of magic and miraculous lore, waiting to be unveiled.
