About This Game

A boy thirsting for power, and a girl who has lost her memory,

In the twisted world of Valhalla, what destiny awaits them?

Series Overview

This game is a mobile game app that was exclusively released for Japanese flip phones.

It inherits popular game systems from the Shin Megami Tensei series, such as a system that allows you to communicate with demons and recruit them as allies, a system where you can fuse allied demons together to create more powerful ones, and a system where the protagonist's alignment shifts between "LAW" and "CHAOS" based on his actions.

Game Story

Set in the near-future city of TOKYO Millennium, built after the Great Destruction, the game follows a boy living in the slums of "Valhalla," a residential area of the city.

One day, after being spotted by the Temple Knights during a fight, the boy is pursued. He then meets a mysterious man through a friend who offers to help him grow stronger, on the condition that the boy defeats the ruler of Valhalla, who controls the people. In exchange, the boy receives a "COMP."

To train, the boy descends into the old underground city, where demons roam, and encounters a mysterious girl who has lost her memory.

What will the fate of these two characters be as their story unfolds?

Gameplay Features

The game not only features demon fusion ("Demon × Demon") but also allows players to fuse demons with swords to create powerful weapons.

By using specific items for "Sword Fusion," players can fuse demons with swords ("Demon × Sword") or even fuse swords with other swords ("Sword × Sword"). The powerful swords created through this process can be equipped by the protagonist to enhance their strength.

As players navigate crucial events throughout the story, each decision they make will dramatically shape the course of the narrative, ultimately determining the fate that awaits them at the end.
