Death Cause: The Same Titan that killed Eren`s mom killed HannesBold text
Hannes is a very caring man, yet a bit of a coward and irresponsible.
He likes Eren and Mikasa, and looks out for them after their mother was eaten.
Hannes is first introduced being near-drunk (while on duty) in Shiganshina District when Wall Maria fell. He saved Mikasa and Eren from certain death, even though he did not have the courage to fight the Titan who ate Carla Jaeger. 
Eren meets Hannes again five years later in Trost District and is surprised to learn that Hannes has been promoted to the rank of Captain. Hannes reveals that he owes a debt to Grisha Jaeger for saving his wife and many others who were ill with a disease by bringing an antibody, and he regrets that he was never able to repay the favor. 
Hannes appears once more as the commander of the Wall Rose counter squad. After Titans mysteriously appear within Wall Rose, it is suspected that there is a breach in the Wall; however, Hannes is surprised to find no sign of a breach and in fact no Titans near the Wall itself.
