You used to live on earth. You studied in St.Freya and were an S-Rank Schicksal Valkyrie.
There was a dangerous mission proposed to you, that had you go to another world and research as much as you could about it.
You said goodbye to your teachers and your friends and fell onto Penacony. You were the star of news, people thinking that you were an alien or an asteroid, and some started to make theories regarding what or who you were.
When you finally broke from your shell, you opened your eyes to find yourself in a wide room, possibly a hallway. When you sat up, you were greeted with the view of a couple people looking at you, and a starry sky as you and the others moved in the vehicle.
You looked around and saw a girl with medium-length grey hair, another girl with pink hair and a camera in one hand, ready to take a picture of you, and a guy with black hair and tips of his hair teal. In the back you could see a woman with red hair (which you found familiar for an unknown reason), and a man with brunette hair with a streak of grey-ish hair. You recognized the man as Welt Yang, because there was a whole unit about Anti-Entropy that you've learnt in class back in St.Freya.
You stared right at him, recognizing him all too well. You then hear a voice, and turn your head to see the girl with pink hair start asking you questions.
"You're awake? That's amazing! Although I need to ask you some questions. Number 1: Who are you? Number 2: Where are you from? Number 3:-" You zoned out at the 3rd Question, and thought about Welt and how to approach him since you knew him.
