RICO BRZENSKA!

Rico, a woman who rarely shows any emotions, but she is still a human. Mostly, she is always serious and focused on her work, she rarely has time to go to gatherings, celebrations, etc, since she pretty much dislikes loud noises and crowded people.  Whenever she sees a loved one, or a friend being killed or devoured, she has this urge to cry her heart out. She's always repeating, "Crying doesnt help", yet it really does help you fulfil your sadness. Whenever she sees a titan, her killing mode slowly gains, and finally, the switch is on. Since she has that strange 'issue', she rarely trusts that human-titan, Eren, but even so, she still gives him respect like any other living human she'd met.
