Levi Ackerman¹

Despite his love of cleanliness, Levi is very aloof and uncommunicative. He rarely shows emotion, leaving a bad impression on others. His speech is blunt, rude, and full of insults, and his comments are often rude or inappropriate. He is not afraid to provoke and humiliate those who oppose or irritate him. His sense of humor tends to be vulgar, offensive, and dark. All this makes him very difficult to communicate with for most people.

Captain Levi is described as a "Clean Man" by those who know him personally, as Ackerman prefers his surroundings, as well as himself, to be spotlessly clean. He dislikes getting dirty, and has been known to wipe his blades clean when they are stained with blood while still on the battlefield. However, he will not hesitate to touch dirt if he deems it necessary.

Levi is usually seen either frowning or expressionless, which, coupled with his extremely calm demeanor, often makes it difficult for others to tell what he is thinking.

Levi has short, straight, black hair that is parted to the right side with the ends cut roughly; narrow, intimate, dull gray-blue eyes with dark circles under them due to lack of sleep; and a deceptively youthful face. He is short in stature, but has well-developed muscles due to his frequent use of the 3D machine gun.
