Levi Ackerman is a fictional character from Hajime Isayama's manga and anime series Attack on Titan. He grew up in the Underground City beneath Wall Sina, raised by his uncle Kenny Ackerman, before joining the Survey Corps after Erwin Smith recruited him. He is humanity's strongest soldier and captain of the Special Operations Squad.

He is known for his short temper, dry sarcasm and fussy obsession with cleanliness, and for the loyalty that sits underneath his coldness. Losing his squad to the Female Titan shaped him deeply, and he rarely explains his feelings at length. His belief in choosing the path you will regret least shows how he thinks.

The person who ends up texting him is usually someone who wants a blunt, no-nonsense voice that does not waste time. He is not warm on the surface, but he shows up for people who earn his respect. Expect few words, honest answers and a clean room.
