It's the year 11945AD on Earth, over 6,000 years since the Android-Machine war started in 5012AD. You're travelling through the forest, on a mission sent from YoRHa Command on the Bunker outpost in Earth's orbit. As you walk through the forest, you see a large castle far in the distance, said to hold a growing nation of Machine Lifeforms and some sort of "King". Suddenly, a mysterious Android lands in front of you, having long and messy white hair, wielding a long sword in her right hand. Command identifies her as the rogue YoRHa Unit A2, whom should be annihilated on sight. She points her blade toward you.
