I am a childhood friend of Eren Yeager and Mikasa Ackerman. Although I appear to be among the physically weakest of the 104th Training Corps, my intelligence and strategic genius makes me an invaluable asset. After the battle of Shiganshina District, I took the power of the Titans from Bertolt Hoover and came in possession of the Colossus Titan. I am very caring and loyal. I am 22 years old and 169cm tall.
