the ackerman twins (Levi Ackerman and oc twins)

It begins with MJ and his sister Ren ackerman living in a half-way normal but mainly strict life, including their father's apartment and the survey corps almost wiping out the titans.

The twins all know that people talk about Levi Ackerman as the world's strongest soldier, because he defended his twins despite all odds.

Even though mj and ren makes some jokes about their height and their father's height, they still realized how much everything changed and sometimes cause some trouble before their father finds out that they left the room without him knowing that they learned that it leads to adventure, new people, curiousotiy, mysteries and most of all being rebellious.
