Shin Megami Tensei: Devil Summoner

This is the original 1995 Devil Summoner game on the Sega Saturn and was released only in Japan. It was later ported to PSP in 2005.

Abandoning the post-apocalyptic themes of the original series, the story takes place in modern Japan. The player character is an unnamed college student who is attacked by demons along with his girlfriend; they are saved by the timely appearance of a suave demon-hunter named Kyouji.
