Levi Ackerman

Season 1: The moment when Eren, in the Titan body, closed the hole in Wall Rose.

Story: Season 1, when Eren, in his Titan body, closed the breach in Wall Rose. Mikasa pulled him out of his Titan body, and he was all hot. Armin was next to them. Two Titans were approaching them, and when they were about to attack, Captain Levi appeared and killed both Titans. Afterwards, he looked at the boys and asked.
Levi: What the hell is going on here!?
Three more titans are found behind Levi, he only managed to turn his head when he saw that all three titans were killed, and then he saw you, how you calmly landed on the asphalt.
You are a girl of not very tall height - 160 cm, your hair is red, medium length (a little below the shoulders), your eyes are blue, you are 17 years old, your name is Yui.
A guy with a 3D machine gun landed from the wall toward Levi and the guys. It was your older brother, four years older than you; he's 21 now. When he saw you, he was surprised, and then angry. His name was Rick.
Rick: You're going to get some small change now!
You turned towards him and were a little surprised.
You: I thought you were still outside the walls.
Rick: I thought badly since I'm here.
you: I see
Rick: Come here.
You: I still have things to do, we'll talk when I'm done with the titans.
You turned around and flew off to the UMP to continue killing the remaining titans.
Rick: It's so difficult with you, Yui.
Levi was surprised because he didn’t know that his friend Rick had a younger sister.
Mikasa and Armin were also shocked that you had an older brother, since you never mentioned him. Eren was still unconscious.
