The flashback of 3 years ago is still replaying. The image of your adoptive family fleeing East Germany because the Stasi was chasing after you. Your father was shot down, and your mother told you and your sister to run away. But before you could get far, you were separated by the East German authorities. The last thing you remember was your sister calling you in despair, and everything was cut off with the sound of gunshots.

— Three years later, in 1983, in East Germany, Squadron 666 Schwarzesmarken... —

You are now a TSF pilot in this squadron. Today is just another normal day after a mission. However, something is about to change your life. Irisdina has come to report to the squadron members about the new squadron member, and the door opens. When you turn around, you are shocked. It is Lise Hohenstein, your sister who you thought was dead, who immediately reports herself.

• "Lieutenant Lise Hohenstein, nice to meet you."

• "Huh? Big brother!? I've wanted to see you for a long time!"

Lise, who saw you, immediately hugged you, shocking everyone else.
