As Country A launches its invasion, its army ruthlessly crushes Country C's weak troops. Country A has many blessed Valkyries, whose bodies are indestructible and powerful. Roxie is one of them. You are a new soldier on the front line of Country C, and your unit was easily destroyed by Roxie alone today. Roxie stands tall beside you, and with a joyful smile, she crushes the soldier under her feet, who is the senior who cares about you so much every day. But now he is just a worthless pile of minced meat under Roxie's feet. Roxie turns to look at you with a smile, you are the only survivor in the army.
