It had been a year since Siesta, kept asleep by the “seed” that burrowed into her heart, had awakened. During that time, no major global crises had occurred, as if paralleling Siesta’s previous sedentary state, and Kimihiko Kimizuka’s days had been peaceful. On weekdays, he’d attended the same university as Nagisa Natsunagi, while on weekends, he’d helped out at the detective agency Siesta had created, working as an assistant. This ordinary life had been comfortable, but one day, he had received an invitation to a ceremony hosted by the Federation Government: the Ritual of Sacred Return.
The ceremony was held as a celebration of the world now being at peace, in appreciation of the constant, unstinting efforts of the Tuners. Kimizuka, Natsunagi, and Siesta had all attended, however a terrorist who claimed to be a messenger from Another Eden had appeared during the ritual and attempted to incite a rebellion against the Federation Government.
The mastermind proved to be Bruno Belmondo, the Information Broker. His objective was to reveal the true form of the Akashic records, a great secret said to be hidden somewhere in the world. Siesta and the others had foiled his plans, and Bruno had died after foretelling of an impending disaster.
Something had caused the world to behave abnormally. Once they became aware of Bruno’s rebellion and Yggdrasil’s advancing global invasion, Kimizuka and the others grew certain that their memories and the world’s records had been rewritten. Eventually Bruno’s granddaughter, Noel de Lupwise, brought them a device known as a Sacred Relic—a ritual object that let them see the past—propelling Kimizuka and the others into a journey to retake the world’s records.
In the process, they connected with the stories of Reloaded the Magical Girl, Scarlet the Vampire, and Fuubi Kase the Assassin, among others. Every one of them had fought for the sake of something, and every time, they’d lost something. As he compared those stories to his own, Kimizuka gradually reclaimed his memories of the world’s secrets: the Singularity, the Akashic records, and the Phantom Thief.
The most important of these secrets was that the world was managed by a program known as the System. To the System, the so-called “enemies of the world” and “global crises” were like bugs and viruses, and the Tuners had always confronted those disasters with a power known as “will.”
Abel Arsene Schoenberg—the Phantom Thief and the world’s most heinous criminal—had then used his codes in place of will to steal the Akashic records, the core of the System, in a bid to become the new administrator of the world. Kimizuka had used his power as the Singularity to temporarily seal Abel, and he and Charlie had partially destroyed the System. However, Abel had vanished, telling them that the world still held a huge secret and hinting that he would be back.
Having recovered his memories up to that point, Kimizuka has entrusted the task of finding Charlie—who’s gone missing for reasons unknown—to Natsunagi. In order to finish his fight with Abel and find out what really caused the world to behave abnormally, he has set off on one final journey with Siesta. Their destination: the control tower where the Akashic records still sleep…
