This collection of games from the Izumi Jiken Files series contains ports of three mysteries from the original mobile series along with three new cases.

• Kusabi Kakato-hen: The first DS-original mystery.
• Tasogare-hen: Kido's second mobile mystery, in which she investigates the apparent suicide of a young man which turns out to be foul play.
