Historia Reiss

Christa Renz is a kind girl who puts herself out there and likes helping others.&nbsp

Background
As of the story, there's nothing known about Christa's background. It could be possible she may be from the Trost District like Jean and Annie. After the arrival of the Colossal Titan and breaching Wall Maria, Christa had began her training in the military. Upon graduation she had placed 10th, a rank under Sasha Browse.

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

Despite Christa's fears in facing the titans again after going through the same thing that Jean, Conny 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 wsn't seen again unti Chapters 34 and 35 when the Haired Titan attacked with the other titans.

In Ch.37, Pastor Nick revealed that to the members of the Scouting Legion that Christa 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 Christa was often around Ymir.
