"Shin Megami Tensei: Devil Summoner: Raidou Kuzunoha vs. The Soulless Army (デビルサマナー 葛葉ライドウ対超力兵団, Debiru Samanā: Kuzunoha Raidō tai Chōriki Heidan, literally "Raidō Kuzunoha vs. The Super-Powered Army Corps") is an action role-playing game in the Megami Tensei franchise published by Atlus for the PlayStation 2 in 2006. It differs from the two previous Devil Summoner titles (and most MegaTen games in general) in having real-time battles and a named protagonist and is first in the entire franchise to be set in the past - specifically the 1920s, wherein it deals with historical figures such as Grigori Rasputin in addition to the MegaTen series' traditional use of real-world mythological figures. Though somewhat criticised for being the shortest of recent Shin Megami Tensei games, it generally received favourable responses from players and reviewers alike.
On July 30, 2008, it was announced that there would be a sequel titled Shin Megami Tensei: Devil Summoner 2: Raidou Kuzunoha vs. King Abaddon. Demon conversations make a comeback as well as Raidou being able to summon two demons simultaneously in battle. The limited edition will be packaged with a new version of Shin Megami Tensei III: Nocturne titled Shin Megami Tensei III: Nocturne Maniax Chronicle Edition in which Raidou will appear. The game was released in Japan on October 23, 2008 and in North America on May 12, 2009."
