Historia Reiss

Historia Reiss is a kind girl who puts herself out there and likes helping others. As she ran away from home, she went by an assumed name; Christa Renz.

Personality
She is a very useful person who enjoys helping other people, which makes other characters see her as some sort of god.

Background
As of the story, there's nothing concrete known about Historia's background. It is presumed she may be from the Trost District like Jean Kirschtein and Annie Leonhardt. After the arrival of the Colossal Titan and breaching Wall Maria, Historia had began her training in the military. Upon graduation she had placed 10th, a rank under Sasha Braus (this was due to Ymir leaving her the spot).

Current Plot
After the breaching of Wall Rose, Historia wasn't seen going into battle until Ch.6 when she was trying to help Armin overcome his dread of supposedly losing his friend. She helped Mikasa and the other trainees retake the supply room while the rogue titan kept the other Titans distracted. She didn't make an appearance again until Ch.21 when she had shown her Three Dimensional Maneuver Gear as the Military Police was looking for the one that killed the two captured titans.

Despite Historia's fears in facing the titans again after going through the same thing that Jean, Conny Springer and the others, she stayed put and became a member of the Scouting Legion. There, she helped save Reiner, Armin, and Jean by supplying a horse after they were stranded from an encounter with the Female Titan.

She was seen up on the trees baiting the titans and preventing them from entering the forest as the Scouting Legion attempted to capture the Female Titan. After this she wasn't seen again until Chapters 34 and 35 when the Hairy Titan attacked with the other titans.

In Ch.37, Pastor Nick revealed that to the members of the Scouting Legion that Historia may know about the walls having titans inside them because of her family, and that she went under an assumed name after being caught in the middle of her relatives' dispute. It wasn't long until Eren and the others realised that she was often around Ymir.

In Ch.40, she remembers being with Ymir when they were helping Dazz in her hometown. She was confronted for living under an assumed name after being caught in the middle of a serious dispute between her relatives. Before transforming into a titan to fight the other titans attacking them, Ymir made Historia promise her to go back into living under her real name.

In Ch. 41, Historia and the rest of the trainees watch Ymir fighting against the group of Titans nearly falling off the tower when Ymir transformed, to which Reiner questioned her is she knew about it but tells she didn't know herself despite being so close to her and refuses to believe it at first.When the Trainees question who's side Ymir is on, Christa remembers some events of her and along with the other watching Ymir's attempt to fight the other Titan and came to the conclusion that she is fighting to protect everyone.She begins to cheer for Ymir telling her not to die and to break down the tower and celebrates when Ymir does so.She along with the others ride on her back and land on the ground safely, except for Ymir who is eaten by the Titans. As Historia tries to make her way to Ymir to fulfill her promise she is nearly grabbed by a Titan but is saved by Mikasa.

As everyone watches in disbelief at Ymirs wounds and the truth, Historia reveals her true name.

In Ch. 42, she reveals her true name as Historia Reiss to Hanji and pleads with her to go easy on Ymir. While she knew what her friend did was wrong in hiding information that could've been useful to the Scouting Legion, she understood why she did it to protect her comrades. Hanji tells Historia she understands Ymir being a titan like Eren and being an ally of humanity, but the rules are not simple like she thinks. She watches with horror as Reiner in his Armored Titan form grabs Eren and Bertholdt snatches Ymir in his Colossal Titan form.
