Seigai High School is going to be the principal area of investigation. Needless to say that in order to solve the case, Kento will have to find the best strategy talking to the beautiful high school female students...
Kaen Seibo is a Japanese-style adventure which relies largely on conversations and the choices you make during them. However, the game also contains elements of Western-style adventuring. There are items that must be found, picked up and used at appropriate moments. There are areas where you can move through a 3D-like environment, viewing it from first-person perspective. During the dialogues, you also have commands that are accessible through a menu. There are also segments with a time limit.
