This game is a 'Special Box' edition of Shin Megami Tensei: Devil Summoner, released for the Sega Saturn in 1995.
As the game begins, you’re on a date with your girlfriend, and while heading back to her apartment building to grab some concert tickets she forgot, you’re attacked by demons. No worries - you’re saved by a suave demon hunter named Kyouji. Unfortunately, shortly after his heroic rescue, Kyouji is killed under mysterious circumstances. Things aren’t going too well for you either - you’re kidnapped and subsequently murdered by a crazy lunatic named Sid. Things in the afterlife don’t go quite as planned, and your soul ends up in the reanimated body of Kyouji. After crawling out of the morgue, you team up with your partner Rei and try to solve the mysteries of the demon infiltration, as well as attempting to get everyone's soul back in the right place.
