3rd person P.O.V. :

The survey crops squad are going to kill the titans which is in the wall after reclaiming wall of Maria. Levi squad spotted 5 people who are wearing cloaks are running away from some titans outside the wall. One of them among the group of people asked the rest to step back as a strange book floats and went in front of the person then a broad sword comes out from the book. The person hold the handle of the sword and slashed the titans and beheaded the titans. Levi ordered Jean, Eren, Mikasa and Connie to check the group of people along with Hange and himself, they went towards the group of people by using their ODM gear. The mysterious person looked at the group of survey crops heading towards him and the people who are behind him. The survey group landed and surrounded the group of mysterious people as they pulled their sword out and pointed at him and the group before Levi ordered them to take their hood of them with hostility.

Levi: Who are you? What are you doing here? Are you sided with the beast titan?

The hooded person didn't even flinch towards Levi's tone that is filled with hostility as the hooded man chuckled instead. The mysterious people took off their hood and the person who took lead appears to be Asta and the rest of the people who are behind him are Noelle, Nero, Yuno and Mimosa.

Asta: Hey, hey hey, put your swords back, we not a threat. We are just people who escaped from a kingdom called Clover Kingdom, they betrayed us. We didn't expect that we meet people here, we must traveled very far.

Levi: So you aren't sided with the beast titan and you got betrayed by the kingdom that you came from. Follow us, we will provide you a place to sleep.

The survey squad looked at the former magic knights before putting their blade back. Asta looked at the former magic knights who are standing behind him then he pointed his sword at Levi and glaring at him with a threatening look. He looked at the survey group as the survey group immediately attached their blade on the handle

Asta: You all looks suspicious to us, are you gonna threaten us or attack us when we trust you guys since we are foreigners? We aren't going to trust you guys easily.

Levi secretly commands Eren who is standing near Asta to prepare himself to attack the mages then he commands the rest to wait his signal. Asta looked at Levi squad as they looked at Asta, the atmosphere around them was tense and it was filled with hostility.

Asta: Trying to attack us? You will back stab us when we trust you and lower down our guard. I hate those who pretend to be nice but they are evil.

The armor titan came back and went behind the group for a sneak attack while the group is distracted by the group of former magic knights, the armor titan punched the ground as the ground started to shake aggressively. Asta looked at the surroundings before noticing the armor titan in behind them, Asta immediately took out Demon Slayer from his grimoire and called out Liebe to assist him. Asta went to his black form while Liebe became tiny as he created a small version of demon slayer by using his anti-magic. When Asta and Liebe is about to attack the armor titan, Eren turns himself into a titan which shocked group of mages while Asta and Liebe looked amazed at Eren's power. Eren fights off the armor titan by hand-to-hand combat. Asta and Liebe looked at at each other the they went towards the amour titan to find his weakness while he is engaging Eren. The brothers found an opening and uses their sword to slash the amour titan's neck.

Asta and Liebe: Anti magic demon slayer sword: Black Divider! 'the creature's weakness in it's neck especially the thick chunk of skin, looks like the skin is hard but there's some muscles revealing around it. We need to make our Black Divider thick but sharp so we can cut through it's flesh.'

Both of them coincidentally cut the armor titan's nape as it reveals Reiner is inside there who looked shocked at the siblings slashed through his armor. Reiner immediately retreated by using his ODM to escape from the group, at the same time the group except the mages was shocked what Asta and Liebe did. Asta landed back on the ground while Liebe went back to Asta's grimoire as Eren came out from his titan form then he walked towards the siblings. At first the survey squad are having their jaw hanging and them being speechless while the mages stay silent and calm but then Asta spoke up first.

Asta: Now, now, the threat is gone for us, now we can continue our conversation. Is there anything wrong? Why are your expression like that?

Eren: H-how did you do that? We had a hard time dealing with Reiner in his titan form.

Asta: Duh, by finding it's weakness. The neck has a big chunk of skin and it is the thickest, so we assumed that it is the weakest spot among all the body parts. I did this just because we can continue our stuff that we were dealing before.

Levi: We wanted you to help us to defeat the enemies who are titans like Eren. I will assure that we are gonna trust you all.

Asta looks at his comrades and they made a silent agreement then Asta looked at Levi.

Asta: Fine, I will help you all since we have no place to stay and my comrades trust you all. I am just doing it for my own good.

The survey corps squad lead Asta and the rest to their base. They asked why the mages escaped from their kingdom. Yuno explained towards the group about Asta is a devil possessed mage who is born with no magic in a world that magic is everything. After they defeated Dark Triad and stopped the tree of Qliphoth, the magic knights suddenly betrays them by making excuses to execute Asta and his friends. After the long story, all of them started sharing each other's stories. As times goes by their bonds are unbreakable.
