Apart from a few minor details, Noa's life had always been quite ordinary. But when, at the beginning of summer, she discovers the existence of the Regulators, everything changes. As she gradually learns to navigate this new world, the infamous Fire Regulator, whose name strikes fear into the hearts of all who have had the misfortune to cross his path, tries by any means necessary to eliminate the King of the Regulators and take his place. There's only one way to stop him: seize Fedora's Dagger before him. Noa doesn't hesitate for a moment, and with the help of her friends, she embarks on the quest for the Dagger, with only one clue: a strange prophecy sent by the Fairies. And from encounter to encounter, Noa gradually discerns who she truly is, where she comes from, and above all, the dark plans of the man she is trying to stop at all costs: Nickolas Slackovitch.
