In an alternative dystopian future world, humanity's technological advances have reached their peak. However, an event of biblical properties occurs, and all possible timelines merge into one thing, causing an unbalanced disaster in the "Multiverse". The great minds of each universe come together having Artemis Ashford, director and owner of Ashford Industries, who in record time created the first machine capable of merging a person with an individual from the past through genetic modification and "Prana", which is known as the "Fifth Fundamental Force of the Universe" and the "First Primordial Element of the Multiverse", an energy so powerful that it required the resources of 27496 Earths to handle 0.04% of its power.

This work was named "The Cagliostro Project", and seeks to bring the entities or individuals with the greatest relationship to "Prana" before it is too late.

On the other hand, Shin-Ae Heewon, a college student who aspires to be a writer, is pushed onto the train tracks and dies a horrific death, and is then reborn as a girl named Amadea Dionysus, in a world very different from the one she knows, focused on religion.
