Profile

Megami Tensei II

Over 36 years before the game began, a nuclear war destroyed Tokyo and the rest of the world, forcing humanity to hide in bomb shelters and allowed demons to invade and conquer Tokyo.

Shin Megami Tensei

The series of events started with the rising tensions between a Japanese resistance force and the Provisional Martial Law Government set up by the American Army after the sudden appearance of demons in Tokyo. The head of the American forces was actually a disguised demon Thor, acting under orders from Law-aligned forces. He reveals himself to the Protagonist and his party before launching nuclear ICBMs at Tokyo to suppress the demon outbreak, destroying Tokyo in a nuclear holocaust.

Decades later, in a rebuilt Tokyo where demons roam freely, the Messian and Gaian cults have formed. The Messian forces of Law succeed in building a great Cathedral to bring forth God's Millennium Kingdom. This act causes a second Great Flood which again destroys Tokyo, leaving little standing apart from the Cathedral and its inhabitants.

Shin Megami Tensei II

Years later, after the Hero succeeded in toppling high-ranking members of both the Messian and Gaian cults, the inhabitants of the newly-built Tokyo Millennium civilization (built upon the remains of the Cathedral), refer to these two disasters as The Great Destruction. Although both disasters seem to have been brought about by the Law-aligned forces, they were in direct response to the demonic invasions caused by the Chaos-aligned forces.
