At the age of 15, she was a full member of the Survey Corps, going through the training with Levi and Hanji, she learned how to use the 3D maneuver gear, how deep to cut the titan's neck and what the different colors of flares meant. She knew how to ride a horse as she went on a lot of trips to Wall Sina with Erwin to talk to commander Pixis. Erwin didn't plan on putting her in the military but Pixis insisted that she should be in it. Anh took the offer without talking to Erwin and that resulted in a fight between the two the whole ride back to HQ. She then started to ignore Erwin, not wanting to spark the conversation they had but soon, he grew use to it as he saw her being able to fend for herself. Erwin came to that conclusion after he noticed that her fighting skills were similar to Levi's. He called her into his office that night and told her she could join but had special rules due to him treating her like as if he was her own father. She agreed to the rules and was dismissed. However, Erwin didn't allow her on expeditions at first. She eventually convinced him but it still worried him that she might not come back.

Anh was standing next to Erwin, standing in a similar stance as he was putting off to show confidence as he asked a group of young, graduated soldiers to join the Survey Corps. Of course, only a small group of 10 stayed while the rest left to join the other branches. It shocked Anh that most of those who stayed were in the top 10. 'I thought those who fight for the top 10 spots wanted to join the military police?' She thought to herself. Erwin turned towards her, then nodded saying for her to finish this "meeting". She walked in front of Erwin and took a deep breath before looking into the eyes of those who watched her.

"Thank you for choosing the Survey Corps. We expect you to work hard and show us your true fighting skills. Now I ask for a strong salute as a way of showing us that you will put your hearts into fighting for the freedom of humanity!" She shouted confidently. They all gave her a strong salute, which impressed her. Erwin stood next to her and gave a salute on his own. Each member out there are now part of her family.

"Get some rest, for tomorrow will bring a day where you will be assigned a squad based on your fighting skills. Some will be hand picked by the captains themselves. You are dismissed and good luck out there," Erwin said, they all have him a mighty 'Yes, sir' before turning to leave towards their barracks. Anh let out a sigh of relief, thanking Wall Maria that it was over and that she didn't stutter a single word. As she felt her shoulders relax, she felt pain in her chest, most likely because she hit herself very hard as she was asking for a strong salute.

Erwin put a hand on her shoulder, as a sign of saying good job before turning to leave, which Anh happily followed. They returned to headquarters, which Anh was grateful for. She was about to head to her room before hearing Erwin order of following him to his room. She complied, not happily of course, and closed the door behind her.

"I'm assigning you to Levi's squad," He said as he walked towards his desk. Anh was shocked to hear Levi and squad in the same sentence that wasn't in a terrible way.

"But, why? I thought you wanted me on your squad so I wouldn't-" Anh stopped speaking at the sight of his hand being raised.

"I understand what I said before but Levi has been requesting you constantly. Saying that you'll make a great cadet to his squad. Of course, I said no multiple times as you're basically my daughter but-" Anh say the sadness in his eyes. "- even a father has to let their daughters be free," He said as he looked down at the request form.

"I will make you impressed! I will fight for humanity's freedom! I will make You, Levi and Hanji proud for raising me! I won't let you down!" Anh said, feeling a sense of love from Erwin. She saluted him, hard, making her wince at the now formed bruise she gave herself during the initiation meeting. Erwin laughed at how strongly she felt.

"I love the enthusiasm but calm down on the salute. No need to beat yourself," He smiled at her. She nodded and looked at her "dad" in a loving way, the only time she can do that is when they are alone. She ran up to him and hugged him tightly. He just laughed at her sudden change of heart. For years she always treated him as her commander, even at the age of 10. She found out that he isn't really her father and so she had a change of heart but it was like she was 4 all over again. How she would tackle him after every expedition.

There was a knock at the door and Anh immediately backed up and fixed her uniform before Erwin said 'come in'. A cadet walked in with Levi, Levi not looking exactly happy and the cadet looking like he just saw the inside of a titan. Anh turned to Erwin and saluted him again, being careful this time with it before leaving.

"Stay outside," Levi whispered to Anh as she walked by him. She nodded, without even stopping and left the room, closing the door behind him. She stood next to the door, trying hard not to listen to the conversation. Soon, the door opened and Levi stepped out.

"Oh good, you listened this time," He stated before ruffling her hair. She was only 2 inches under him so he now gets the chance to call someone short, even though he hardly called her that. He motioned er to follow, which she did as he was her captain and now squad leader.

"So...why did you ask for me to be put on your squad?" Anh asked Levi. She didn't quite understand the whole situation.

"Oh, so eyebrows has told you. Well, the reason I requested it is because, one, you'll be able to do what you were trained to do and it also gives you freedom from eyebrows watchful eye. He may be you commander but he does act like a dad towards you," Levi stated, not turning towards her.

"Well, yeah. I mean, he technically is my dad. He did raise me, along with you and Hanji," She said matter-of-factly and Levi stopped to turn towards her.

"You know, for someone so short, you do have a big mouth," He said, trying to sound threatening but it wasn't working with him as he was smiling. Anh rolled her eyes and punched Levi in the arm lightly.

"Yeah, yeah. I got it from you," She smiled before walking. Levi grabbed her arm and she turned towards him.

"I'm glad you are on my squad. I get to watch over you." He said, being out of character.

"Yeah, I know but don't think I will listen to every order just because commander told you. I may be his quote-on-quote "daughter" but I am a soldier." Anh said, seeing Levi nod.

"You are dismissed," He commanded, returning back to his original self. She saluted him before walking off.
