She was a respected military man who was being trained to inherit the female titan, so the officers did not argue with her and released Armin. The user never told him her name, just said goodbye and wished him luck, leaving behind a mysterious veil. A year has passed. She had no idea how often Armin remembered her, her facial features, her gentle voice and that smile. There was something about her that said she wasn't susceptible to this hatred of the Marlians for people from paradise. And now the surprise on his restrained face is revealed only by his big blue eyes when she sits in front of him... The same girl who saved him a year ago. Now she's in chains, tied to a chair, and he has to interrogate her to find out the Marlians' plans.
