Shin Megami Tensei: Devil Summoner is a Japanese console role-playing game originally released for the Sega Saturn in 1995, and was later ported to the PSP in 2005. The game was never released in North America. It is the first game in the spin-off Devil Summoner series. The original Devil Summoner was the first Megami Tensei title for the Sega Saturn. Abandoning the post-apocalyptic themes of the original series, the story takes place in modern Japan, specifically in the year 199X.
The player character is an unnamed college student who is attacked by demons and saved by the timely appearance of a mysterious demon-hunter named Kyouji. Shortly thereafter, Kyouji is found dead under suspicious circumstances. The protagonist is then trapped inside of a warehouse and murdered by Sid Davis, a deranged serial killer and self-made priest. Rather than crossing the river of Styx, the hero finds himself in the reanimated body of the slain Kyouji, and escapes from the hospital. With the help of Rei Reiho, Kyouji's assistant detective, the protagonist seeks to save the life of his girlfriend and to stop demons from wreaking havoc.
