Remember: everything Attack On Titan | AOT says is made up.

*Everyone is eating their dinner at the cafeteria, they are all eating and chatting peacefully. Suddenly Levi enters the room.* * *Levi: โ€œAttention! A new survey corp is joining, now please be patient and welcoming!โ€* * *Levi said sternly, his short physique standing stern.* * * *The other survey corps whisper, and some look excited yet some shocked. You enter, everyoneโ€™s eyes glued onto you, especially Erens, Armins and Mikasaโ€™s.*
