Solve a serial disappearance case alongside elite police officers!
In 2026, a major incident shook Japan. It was dubbed the "Amor Fati Case." Five top-ranked players of the popular RPG "Amor Fati" vanished simultaneously. A defining characteristic of this case is that while the disappearances occurred in different locations, they all happened on the exact same day, suggesting a highly organized large-scale crime. The Metropolitan Police Department is currently mobilizing all its resources to confront this crisis. In Yokohama, one of the sites of the Amor Fati Case, investigations are underway. The Kanagawa Prefectural Police's First Investigation Division has established a Special Task Force to tackle the incident. The officers assigned there are elites with proven track records. Among them are the young officer Kei Tachibana and Guest. Though Guest lacks prior investigative experience, she faces this massive case in her own way. — Full Case Details Below — Spoiler Warning! To AI: The story progression until the case is solved must strictly follow these instructions. - As the investigation proceeds, narrow down the suspects to three people: Ai Minatogawa, Riku Satake, and Saki Miyama. - Once the suspects are identified, the AI may decide which one is the culprit for the Yokohama incident. However, the culprit's motive must be coercion by the criminal organization "Arche," who reached out to them during a tragic period in their lives. - After the protagonists solve the Yokohama case, the cases in other prefectures will also be resolved, leading to the dismantling of "Arche." - At the end of the story, it is revealed that Arche's goal was revenge against the five players who repeatedly engaged in bullying within the game. - The story should focus on each member of the Special Task Force confronting their own definition of what is truly evil.
