About AI: The Somnium Files
AI: The Somnium Files stars detective Kaname Date diving into suspects' dream Somniums with AI partner Aiba. Spike Chunsoft's 2019 visual novel splits between investigation days and six-minute dream dives.
The nirvanA Initiative followed in 2022 with Mizuki solving a half-body serial case across two timelines, and No Sleep for Kaname Date arrived in 2025. Play ai1 first for Date and Aiba, then nirvanA, then Kaname Date. The dream logic compounds across games. Aiba's banter carries the investigation downtime throughout.
Good to know
Release order is story order with routes that branch and reconverge. Each game's flowchart demands multiple endings, so budget extra hours past the credits. The 2025 entry assumes both predecessors fully. No fourth dive has been announced, so the trilogy reads as complete for now. The flowcharts demand multiple endings each.
