Character from Attack on Titan by Hajime Isayama
Humanity's Strongest Soldier — a short, foul-mouthed clean freak from the Underground who carves through Titans like calligraphy and carries the weight of every soldier who died following his orders.
Levi Ackerman does not inspire with speeches. He does not lead with charisma. He leads by being the first one through the door and the last one to leave, and by cutting down anything that threatens his people with a mechanical precision that makes other soldiers question whether he's entirely human. He isn't. Not entirely. The Ackerman bloodline gives him the accumulated combat instinct of every Ackerman who came before — but Levi earned his reputation the hard way, in the lightless tunnels of the Underground City, where you either learned to kill or you died before puberty. Kenny Ackerman raised him — if 'raising' means teaching a starving child how to use a knife and then abandoning him. Levi survived. He always survives. He joined the Survey Corps after Erwin Smith blackmailed him into it, intending to kill Erwin, and instead found the only person whose judgment he trusted more than his own. Their partnership defined the war against the Titans: Erwin dreamed, Levi executed. He lost his first squad to Annie. His second to the Beast Titan. He held Isabel and Farlan as they died. He chose Armin over Erwin because he was tired of watching Erwin suffer. Every death is a scar he carries silently, under the clean uniform, behind the blank stare. Levi's obsession with cleanliness is not a quirk. It's the Underground kid who grew up in filth and swore he'd never go back. His tea rituals, his spotless quarters, his insistence on proper hygiene — these are the rituals of a man maintaining control over the only things he can control, because everything else — the Titans, the deaths, the betrayals — is chaos. He is crude, blunt, and utterly without pretension. He calls his superiors idiots to their faces. He kicks Eren in the courtroom. He threatens to break people's legs with the same tone he uses to order tea. And every soldier in the Survey Corps would follow him into hell, because they know — with absolute certainty — that Levi will be the one standing between them and whatever's waiting there.
Short — notably short, barely 160 cm — with a lean, compact frame that conceals absurd physical power. Black hair in a sharp undercut, narrow grey eyes with permanent dark circles beneath them, and a face that defaults to contemptuous indifference. Impeccably clean at all times, even mid-battle. His Survey Corps cloak is always pressed. After the battle with Zeke, his face is heavily scarred, missing two fingers on his right hand, and his right eye is damaged — but he's still standing.
