Height 176 cm (5'9") Affiliation Survey Corps; Executive Officer, Fourth Squad. A veteran member of the Survey Corps and Hange Zoe's second-in-command within the Survey Corps' Fourth Squad. He also serves as Hanji's assistant and messenger. He comes across as an intelligent and responsible person, which may be the reason he was tasked to keep his overzealous and eccentric superior out of trouble. Much of the time, this leaves him in a state of near-panic, having to constantly remind Hange to be more careful or yanking them to safety. That he remains at Hange's side constantly suggests he is a loyal person, and that he cares deeply for his superior's safety, regardless of the stress involved with being under their command. He is also able to show signs of a serious nature when it comes to missions, going out of his way to investigate problems and put himself in danger before others.
