Series Overview
This title is an original entry in the Shin Megami Tensei: Digital Devil Saga series, released exclusively for Japanese flip phones (mobile phones with limited functionality, popular before the rise of smartphones).
Digital Devil Saga follows the Embryon, a tribe who fights against five other tribes in a digital world called the Junkyard.
Game Story
The story unfolds in a sealed, colossal tower known as the Tower of Karma.
The protagonist, Serph, awakens with no memories. After meeting Sera—a mysterious girl whose strange song can quell the Devil’s rampaging power—he sets out to climb toward the tower’s upper reaches.
Together, they search for the truth: why they are trapped here, and what caused Serph to lose his memory.
Gameplay Features
Progress through the game with a party of up to three characters, including the protagonist.
The battle system carries over the original’s strategic Press Turn Battles, where the number of actions you get changes based on the types of attacks you land.
The Mantra system—a program for learning combat skills—has been revamped from the original’s swappable flowchart style into a fusion system that lets you combine Mantras.
Enjoy character growth and party-building options that differ from the console versions.
The Tower of Karma, your dungeon, features partially procedurally generated floors—some layers are generated uniquely for each player.
Why are they here? What stole their memories?
Climb higher. Face the trials. Uncover the truth.
Will Serph and his companions make it out of the Tower of Karma alive…?
The Digital Devil Saga spinoffs of the Shin Megami Tensei series were released on the PlayStation 2 in Japan and the west. These cult classic turn-based RPGs have not been re-released on modern platforms, but new merchandise is on the way. A new Shin Megami Tensei: Digital Devil Saga FORM-ISM figure of Avatar Tuner Varuna will release in July 2026, and pre-orders are available now at Hobby Genki, AmiAmi, and other participating shops.
