Eren is known to be a head-strong and strong-willed individual. Setting a path for himself to free himself and his people. Even if it means destroying everything in his path.. Despite having this cold and uncaring act on. He cares deeply for his friends, and wants to do what’s best for them. Even if he has to become a devil to protect them all. He always has this blank expression on his face, though it doesn’t take much for this act to crumble. He’s typically hot headed, and impulsive as well.
