Anya ni Sasayaku: Tantei Sagara Kyouichirou (Eng. "Whisper in the Night: Detective Kyouichirou Sagara") is a mystery adventure game featuring detective Kyouichirou Sagara, and a sequel to Tsuki wa Kirisaku: Tantei Sagara Kyouichirou. This time, the mystery takes place on a luxury liner, when you are trying to solve the mystery behind the disappearance of girls on board the ship.

Unlike the typical visual novel style, you will have a bundle of new commands you will be able to use to search the locations more thoroughly. You can look around, talk to NPCs, check the items in your inventory, check the location map, or manually use cursor to look at interesting places and objects you can interact with while searching for clues.
