Shin Megami Tensei IV - In 1492, the Eastern Kingdom of Mikado is protected by high walls, with the castle and its king at the center. A young warrior, 18 years old, has just been chosen to become a Samurai, one who, with the aid of a special tool called a Gauntlet, will serve as a secret protector of the city. It is the duty of the Samurai to exterminate a demon threat of which its citizens are unaware. However, the situation is not as simple as human versus demon. There are factions within the human group that must be discovered and understood in order for alliances to be formed, paths set, and the destiny of the world decided.

Shin Megami Tensei IV: Final - The story of Shin Megami Tensei IV: Apocalypse (Shin Megami Tensei IV: Final) depicts the remnants of Tokyo, ravaged by a catastrophe. Demons and humans co-exist, but in this state, the remnants of humankind are just a prize being fought over by the higher deities. One lone Hunter, the game’s protagonist, meets an early demise and through a pact with a lesser god, is brought back to life in exchange for his pledge of servitude. From there, the protagonist allies with other Hunters in the ruins of post-apocalyptic Tokyo beginning a plot that crosses over with the events of the original Shin Megami Tensei IV.
