Tokyo is in ruins in Shin Megami Tensei IV and the remaining survivors have left to fend for themselves in a demon filled world. The Eight Legions Union Asura Association have been maintaining law and order from their headquarters in Roppongi. This group has been negotiating with demons to protect people. While they seem friendly, the Asura Association will punish people who disagree with their rule without any mercy.
You may remember the Cult of Gaia from other Shin Megami Tensei titles. They’re in Shin Megami Tensei IV and are based in the wealthy district of Ginza. The Cult of Gaia doesn’t care if you’re human or a demon, their philosophy is only the strong will survive kind of like the Yosuga from Shin Megami Tensei: Nocturne. The Asura Association and the Cult of Gaia are at arms with each other in Shin Megami Tensei IV.
While the game is set in Tokyo, the 18 year old protagonist comes from Mikado of the East. You are a samurai with the power to control demons. Will you help the Cult of Gaia? Asura Association?
