Nanaba

Nanaba (ナナバ) was a member of the Scouting Legion until her death.

Story
Nanaba first appears during the 57th expedition as a Commander for apparently Christa's unit, who was worried about the Titans climbing the Trees. Nanaba just calmly replied if they climb up, she just moves away and tries to assure Christa that they only have to hold out a little longer, most likely referring to the capturing of the Female Titan.

She is also one of several soldiers (the others being Gerger, Henning, and Rene) brought by Mike Zakarius to oversee a group of potentially untrustworthy Scouting Legion members. The group was assembled close outside of Wall Sina, and disarmed of their weapons due to the suspicion that one of their number might be an accomplice to Annie Leonhardt.

Before an investigation can begin, Titans appear within Wall Rose. Mike orders the group to split into four squads to warn the nearby villages. Nanaba's squad searches Wall Rose for a breach, but runs into Gerger's squad coming from the opposite direction without finding any. As night falls, the two groups take refuge in Castle Utgard.

Castle Utgard soon comes under attack from numerous Titans capable of moving during the night. Since the soldiers who'd been under suspicion don't have Three Dimensional Maneuver Gear, the only ones able to directly engage the Titans are Nanaba, Gerger, Henning, and Rene. However, Henning and Rene are soon killed by a projectile thrown by the Ape Titan, and Nanaba and Gerger quickly exhaust their reserve of gas and swords.

When Gerger falls off the castle wall due to an injury, Nanaba jumps down and begins killing Titans in an attempt to save them. However, their 3DMG runs out of gas, and they are eaten.

Trivia

 * According to Erd, she was one of the few survivors of "5 years ago", alongside Hanji, Levi, Mike and Irvin. Her survival also is said to be the reason why she was among the few who knew about the truth regarding the 57th Expedition and most likely is the reason why alongside Mike, she was watching over the Graduates. At any rate, she was one of the few that Irvin seems to have trusted.
