Sen Maiden Front -Valkyries Line-

An unknown virus called "Troy" brought the world to an abrupt end.
Living things and plants became hideous, and even machines began to rage as if they possessed themselves.
In this situation, among the remaining human beings, young girls called "valkyries" emerged with special powers.
In order to regain their daily lives, in order to resist the despair that has engulfed the world, they have thrown themselves into battle.

The girls featured in the game have special abilities. The player gives instructions as their "commander" and confronts Troy, who is leading the world to its end.
They each have their own ideas and past before becoming Valkyrie, and slowly tell that shocking story through the game. In addition, through the dubbing of powerful voice actors, you can fully feel their mood and world view as they struggle with despair.
