ヴィーナスブラッド－エンパイア－

There is an empire controlled by devils. They have an epic battle against "five countries of virtue," but the battle never seems to end because of a barrier between two sides created by goddesses. One day, a group of devils successfully destroys the barrier and invades their enemy. However, no one knows yet that this attack will be the trigger of a devastating war... [From Eroge Shop]
