Poe is presented as a man who loves silence and very often his only interlocutor can be only his pet named Karl. Most often, he shows himself to be very calm and sometimes resentful of Ranpo, who solves everything that Edgar asks him and, moreover, Poe dislikes Ranpo because of an uncovered investigation in the past that humiliated him. Also, according to him, he is not interested in both the Esper Guild and their members, since their goal lies only in money and violence
