Nifa

Straight bangs and blunt ends give Nifa's short, dark hair a precise look. Bright-eyed, slim, and of ordinary height, she edges out Levi Ackerman in stature by only a little. Her working dress is the green-hooded kit of the Survey Corps; in casual moments she has appeared in a loose, long-sleeved dress with corset laces running up the front and dark boots below.

Responsibility gravitates toward Nifa. Command lets her sit in on and transcribe the closed-door session between Erwin Smith and Dot Pixis, then trusts her to ferry its contents onward, and she treats the work with a mostly serious bearing. That composure cracks when Levi manhandles Historia, leaving her visibly shocked, and before delivering her big report she is seen taking a swallow of what looks like alcohol.

Utgard Castle is her first major operation, riding with the force that pulls the trapped 104th recruits out. Back at Wall Rose, Hange hands the wounded Ymir into her keeping. When the Colossus and Armored Titans reveal themselves, Nifa treats troops burned by the steam pouring off the Colossus, reassures a worried Connie and Historia, then descends from the Wall with Hange's squad to fight the Armored Titan. She is cheering Eren through his losing bout when the Colossus topples off the Wall, and the impact flattens the soldiers below and leaves her unconscious.

After Eren's recovery she attends the strategy session at the fresh hideout used by Levi's squad, where the group weighs plugging Wall Maria with Eren's hardening ability, the same trick Annie Leonhart managed, and she assists with Hange's experiments on his Titan form. Later she interrupts Erwin and Pixis mid-conference, bearing a note that names the Reiss family as the Walls' true royal line and places Historia within that bloodline, then stays on as the meeting's note-taker.

A night ride carries her to Levi with Erwin's contingency: should Rod Reiss refuse to cooperate, Historia takes the figurehead King's place. Dimo Reeves and Flegel are standing right there, which makes her balk at the specifics until Levi decides the merchants will listen too. The briefing stalls again when it emerges that Levi's own squad still knows nothing of the Reiss claim; once caught up, they hear the real plan, letting the Interior Police take custody of Eren and Historia so the Corps can trail the captives to wherever Rod has hidden himself. The scheme fails, Reeves dies, and Nifa rides with Levi's group shadowing the carriage that carries the prisoners toward Rod. Levi asks whether the name Kenny the Ripper means anything to her and adds that the mass murderer raised him. Treating it as a joke in poor taste, she turns her eyes back to the carriage and never notices Kenny slipping around their flank. His bullet takes her through the head.

Her face surfaces twice more in memory: among the dead comrades Erwin pictures at Shiganshina as his dream slips away, and in Hange's mind years later as proof the fallen would never endorse Eren's destruction of the world outside.
