Hogwarts Houses for Levi's Squad
Mikasa - Gryffindor
A lot of people would think she is in Slytherin. But here's my reasoning. Mikasa didn't join the Survey Corps, just because she wanted to kill titans and free humanity. It's one of her reasons, but the main reason was simply to protect Eren. She would do anything to protect him, so you could say that makes her ambitious enough to be in Slytherin. Although Slytherin's goals were more about themselves then others. But besides that one thing, there are some traits that make her a Gryffindor. She is very brave. Back in season 1, she almost gave up, because believing that Eren was dead made her think that she had nothing left to live for. However, she snapped herself out of it, and decided to fight anyways, with nothing but a broken sword. That is what makes her brave. And reckless, too, as she could've tried to run instead of charging to her death. Not that either is a wrong decision. Even as a child, Eren gave her the courage to stand up to her oppressors even though she was small and frail. If it means protecting the people she cares about the most, she will do the most reckless things, even more so than Eren, probably. Also a high key Gryffindor trait. Levi had to hold her back so many times, because she was so quick to jump into danger without thinking of what could happen to herself or what she'd do to make it worse. She is also short tempered. Mentions of harming or disposing Eren or Armin easily pisses her off. She will throw hands before anything could happen.
Hence, why Mikasa is a freaking Gryffindor through and through.
