Subete ga F ni Naru

Genius programmer Shiki Magata has lived in seclusion for years inside a research facility on a remote island, allowing almost no one close to her. Associate professor Souhei Saikawa and student Moe Nishinosono travel there hoping to meet her, only to become trapped in an impossible murder mystery inside a tightly controlled building. No one appears capable of entering or leaving, yet a crime occurs despite layers of security. Saikawa and Moe begin pulling apart the contradiction, but every clue leads deeper into Magata's past and toward a truth that makes the locked room itself only one part of the puzzle.
