"The Devil Summoner series started on the Sega Saturn with two titles: Shin Megami Tensei: Devil Summoner in 1995 and Devil Summoner: Soul Hackers in 1997. The series returned in 2006 with the release of Shin Megami Tensei: Devil Summoner: Raidou Kuzunoha vs. The Soulless Army and its 2008 sequel, Shin Megami Tensei: Devil Summoner 2: Raidou Kuzunoha vs. King Abaddon, both for PlayStation 2. Unlike the previous entries in the series, which are traditional turn-based games, the Raidou Kuzunoha series consists of real-time action games with role-playing elements. Raidou Kuzunoha, the series's titular protagonist, is a detective living in early 20th-century Japan and the 14th in a line of demon summoners.
This series is one of the many Spin-off series of the Megami Tensei."
