Summary
Atsushi Nakajima isn't the naive, morally upright person everyone believes him to be. Secretly, he's a hidden member of the Decay of Angels, and, even more shockingly, Fyodor Dostoevsky’s son, raised in secrecy to become a cunning operative. He was tasked with infiltrating the Armed Detective Agency and slowly breaking it from within, gathering intel to further Fyodor’s goals. Atsushi’s outwardly gentle demeanor masks an unstable mind and a chilling lack of morality. Internally, he's always calculating, detached, and fascinated by the darker facets of humanity. His transformation into the innocent persona has been meticulously crafted by Fyodor himself.

Named after the song 'A Trophy Father's Trophy Son' by Sleeping With Sirens
