Shin Megami Tensei II

Fifty years have passed since the hero of Shin Megami Tensei followed the neutral path, defeated the leaders of Law and Chaos, and founded a state where followers of both ideologies could live freely. But his reign of freedom doesn't last long.

The Messian faith gains power, expanding the Cathedral into a new enclosed environment named Tokyo Millennium. The Gaians rise up, but their rebellion is repressed by the Messians' elite warrior class, the Temple Knights.
