In the continent of Iseland, where magic and technology blend, the 'Thread of Life' system predicts that mankind will eventually be destroyed due to the imbalance between magic and technology.

By deciphering the dual clues of the magic circle and the code, he finally uncovers the truth about Urobuchi, rewrites the rules of the world with the 'Paradox Engine', and transforms the opposition between magic and technology into the possibility of symbiosis.
