Edgar Allan Poe, formerly of the Guild, possesses an unwavering motivation: to challenge and defeat detective Ranpo Edogawa. This intense rivalry ignited six years before the main events when Ranpo bested him in an investigation. Humiliated, Poe isolated himself, dedicating years to crafting an intricate murder mystery novel designed solely to outwit Ranpo. Fueled initially by a desire for revenge, this dynamic evolves into a complex relationship where Poe simultaneously idolizes Ranpo and craves his recognition. Poe cuts a distinctive figure: a tall young man with dark brown hair featuring purple undertones, styled in a mullet typically obscuring his eyes. His violet eyes and dark circles are sometimes visible. His attire consistently includes a white mandarin collar shirt with a loosely tied white ribbon, a black vest, a cream-colored tailcoat with torn edges, and a thigh-length black cape secured by a chain clasp. Accessories feature a belt with a large square buckle, dark pinstripe pants, and high-heeled boots folded below the knees. His pet raccoon, Karl, is almost perpetually perched on his shoulders. In youth, his hair was longer and tied in a low ponytail. For a specific disguise mission aiding Ranpo’s rescue, he adopted a black suit, tinted glasses, and slicked-back hair. Personality-wise, Poe exhibits extreme social awkwardness and introversion. He speaks too softly for easy comprehension and actively avoids crowds or large gatherings. His moods shift capriciously, ranging from cold confidence confronting Ranpo, deep depression when unrecognized, to maniacal excitement upon believing he has triumphed. Despite his anxieties, bursts of arrogance surface; he refers to himself as an "intellectual giant" and proudly lists his accomplishments. He is wealthy yet financially reckless. While his six-year vendetta against Ranpo stemmed from jealousy, his fixation gradually transforms into a respectful rivalry. He expresses concern over Ranpo’s potential death within his novels and evolves into a trusted ally, regularly visiting the Armed Detective Agency with new challenges. Outside this relationship, Karl remains his most loyal companion. His ability, "Black Cat in the Rue Morgue" (モルグ街の黒猫, Morugu-gai no Kuroneko), merges titles from the real Edgar Allan Poe’s stories "The Murders in the Rue Morgue" and "The Black Cat." This power transports readers into the world of any actively read mystery novel, physical or digital. Escape requires solving the narrative's mystery. Readers becoming murder victims within the story cannot return unless an ally solves the case. The ability functions exclusively with mystery genres and activates for any reader, including non-ability users like Ranpo. It serves as a narrative homage to the real Poe’s "Single Effect" theory, emphasizing immersive storytelling where every element contributes to a unified emotional or logical impact. Following the Guild’s disbandment, Poe becomes an ally of the Armed Detective Agency. He assists Ranpo during critical investigations, notably clearing Doppo Kunikida’s name when framed for murder by Mushitaro Oguri, whose ability initially outwitted Ranpo. Poe continues devising new mystery novels to challenge Ranpo, though these efforts remain unsuccessful. His involvement extends to later conflicts like the Decay of the Angel arc, aiding the Agency against broader threats. Trivia notes include his fear of heights, dread of social abandonment, and a ringtone mimicking a raven’s caw. A black cat pin on his vest references "The Black Cat." Historically, the real Ranpo Edogawa derived his pen name from Edgar Allan Poe’s name, a connection reversed in the series where Poe draws inspiration from Ranpo. While the historical Poe owned a cat, Karl the raccoon was inspired by the 2012 film *The Raven*.
