Kaiketsu Nikki is a first-person adventure with elements of an anime/manga game and an adult game from developers Ange. The main publisher of the game is Ange. In some circles Kaiketsu Nikki is also called 𤘘傑NIKKI. The PC version of Kaiketsu Nikki, unfortunately, has not yet been released, but we hope that the release will take place in the near future.
