OZ, a globally connected virtual realm, has surged in popularity as a hub where users craft and personalize avatars to partake in diverse pursuits like sports, retail, and more. The platform boasts virtually impregnable security thanks to robust encryption, safeguarding all personal data transmitted across its networks and shielding its users. Its convenience has made the majority of society heavily reliant on this simulated domain, to the point where it was entrusted with reviving the unmanned asteroid probe Arawashi. Users rely on OZ for everything from education to medical consultations, making it a staple of modern life.
Seventeen‑year‑old prodigy Kenji Koiso, a part‑time OZ moderator and math savant, is invited by his crush Natsuki Shinohara on a summer excursion. Unbeknownst to him, the trip demands that he assume the role of her betrothed. This unexpected role places him at the center of a social ritual that could alter his future. Shortly after arriving at Natsuki"s family estate—preparing for her great‑grandmother"s 90th birthday—he receives a mysterious encoded message on his phone from an unknown source, challenging him to decipher it. Kenji solves the puzzle, yet he remains unaware that his numerical prowess has inadvertently endangered Earth. The solution, however, triggers an alarm within OZ"s core systems, hinting that the platform's encryption may be compromised.
