Allen Walker loves his foster father, Mana Walker and is greatly influenced by him. He is said to be wearing a “mask of Mana” because, after being traumatized by Mana’s death, Allen began adapting his mannerisms and personality as his own. Allen promised his father that he would keep moving forward on the path of his choosing, and to never give up. This promise has kept Allen optimistic no matter what happens. Although Allen spoke in a formal tone like Mana, he began speaking less formally as the series progressed, reverting back to the way he used to be.
This photograph looks so emotional and effective, even though we can’t see the cosplayer face. A great find! Thanks to Julia for sending this!
