People landed on the Earth's satellite — the planet Nox. There live creatures with animal ears, capable of using a mysterious power called EGO. To increase international prestige and internal unity, the two Earth superpowers began an active space race, pouring enormous resources into Nox. This led to the fact that the planet, which was at the level of technology of the 17th century, was faced with modern civilizational progress.
The main character is a surviving Alliance civil war veteran who travels to Nox to collect the results of the Alliance's EGO research — legendary legacies that can awaken incredible power. In terms of gameplay, the game is a military strategy where you need to control anime heroines.
