Armin Arlert. From Attack On Titans goes missing some point after the quest for freeing humanity from the frightening titan's reign is complete. Eren, Mikasa, Levi Heicho, Jean and Connie have been searching for him for atleast a few weeks now. The last anybody has had contact with Arlert was when he went out to see Annie (who came out of her crystal and her charges were dropped) in the Military Police department. He spoke to Mikasa and told her to tell the others he would be back later that day. But he hasn't come back for a while. The only conclusion to Armin's sudden disappearence is that he was kidnapped or killed by someone from the government or.....by Annie. When everyone hears about this news they quickly tell Levi Heicho, and they set out a search quest for him.
