Nikki

Nikki (ニッキー) is part of Bernhardt's band of outlaws. She appears in the light novels Attack on Titan: The Harsh Mistress of the City, Part 1 and Attack on Titan: The Harsh Mistress of the City, Part 2.

Appearance
Nikki is a young woman who is short in stature, but shapely with lightly colored hair. She has an aloof appearance, accompanied by a barely perceptible grin. Nikki appears to be around twenty years old and is wearing a new soldier's uniform when Mathias Kramer first meets her.

Personality
Nikki has a mellow personality, though this results in her appearing to be lazy or unthinking. However, she is able to keep a cool head even during stressful situations. Mathias Kramer thinks she is capable of eliminating him should she feel he did not hold up his end of the bargain, and when he is spotted by Rita Iglehaut after the death of Duccio, Nikki is able to quickly and efficiently extract both him and herself without panic.

Unlike Bernhardt, she has no problem calling their band of outlaws for what they are: thieves. Nikki is joyfully unrepentant about her illegal lifestyle, but becomes considerably more serious after she gets trapped in Quinta District with no way out.
