Although Levi is known to be unapproachable and cold, he places great value on preserving human life. He once stated that he hates having unnecessary casualties and advised his subordinates to use their judgment properly to avoid any mistakes that may cost them their lives. When they later discovered that titans were once humans themselves, Levi appeared to be mortified by the news.
Another amazing cosplay by Taiwanese cosplayer, Oh Ye Ya (夜伢)! I really love all these different colors the fans have made for Shingeki no Kyojin. I think the black one may have been my favorite until now. Red looks surprisingly good on Levi! Thanks to Genevieve for sending this in!
