But something goes wrong.
It seems like a virus that creates a fire substance inside of human beings' bodies.
The disease soon became known under the name "Spontaneous Human Combustion".
Particularly one district of the newly built Izanami City seems suspicious.
Kento Rando, a high school student and an apprentice detective, is given a mission to investigate the mysterious case.
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.
About Sega Dreamcast
Sega's final console, the Dreamcast (1998/1999), was ahead of its time with built-in internet connectivity and an influential library, but a short commercial lifespan cut its game catalog short. That abrupt end means Dreamcast print runs were smaller across the board than a longer-lived console would have had, and it's now one of the more actively collected fifth/sixth-generation systems specifically because of that scarcity.
Gamevaro tracks Kaen Seibo for Sega Dreamcast with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Kaen Seibo to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This DC release dates back to 2001.

Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
