Edgar Allan Poe/Synopsis

History
Six years ago, Poe was beaten by Ranpo Edogawa in an investigation competition. The defeat led to him withdrawing himself from his personal connections and becoming extremely secluded and depressed. However, this defeat also inspired him to take back the life that he felt Ranpo had stolen from him.

At some point, Poe later joined the gifted organization known as the Guild and came to Japan in order to challenge Ranpo directly.

The Guild Arc
During the three-way conflict among the Armed Detective Agency, the Port Mafia, and the Guild, Poe sends Ranpo a letter inviting him for a challenge. When Ranpo and Akiko Yosano show up, Ranpo asked who Poe is. Much to Poe's horror, Ranpo did not remember who he was. Afterward, Poe presented Ranpo and Yosano with a novel that he wrote, telling Ranpo and Yosano that if they were able to solve the mystery behind the murders in the novel, he would tell them about the Guild's weakness. When Ranpo asked him why he would care about something so pointless, Poe said that the only thing worth admiring in the world was Ranpo's Super Deduction, much to Ranpo's delight. Ranpo and Yosano then begin to read the novel. However, Poe used his ability and transported Ranpo and Yosano into the setting of the novel.

As time passed and it appeared that Ranpo and Yosano seem to have made no progress in solving the mystery, Poe stated that Ranpo will never be able to solve the mystery, and declared that the novel was his revenge on Ranpo. When Yosano was murdered in the novel, Poe rejoiced and said that Ranpo would be lost in his novel forever if he could not solve the mystery.

However, Ranpo and Yosano immediately returned from the world of the novel afterward, having solved the case. When Ranpo revealed the answer to the mystery, Poe was devastated. However, Ranpo revealed that he still remembered their match from six years ago, stating that that was the first time he had been pushed to such an extent by another detective. As Ranpo left, Poe told himself that he still had a lot of work to do.

After the Guild War, he appears at the Agency's party, having brought over his newest manuscript for Ranpo to read after the latter said that he wanted to see them. Ranpo urges him to come inside the room, much to Poe's timidness and apprehension given that he came from an enemy organization. Ranpo cuts him off, asking him to stay put and wait for him to finish his conversation with the others. Kenji approaches him and asks if he likes to have some drinks while waiting. Poe mutters to himself on what kind of drinks are served at such kinds of events, upon which Kenji remarks that he cannot hear him. In the end, Poe tells Kenji that he does not need anything and anxiously waits amidst the commotion.

The Guild Aftermath Arc
Louisa May Alcott approaches Poe and asks him to help solve the case of T. J. Eckleburg murdering his co-worker for her and Francis Scott Key Fitzgerald. Even though Poe did not want to be involved with the Guild any longer, he agrees to help Alcott, considering her as a "comrade in shyness". Later, Poe brings the information of the case to Ranpo in the form of a mystery game, asking him to solve the case.

Cannibalism Arc
During the events of cannibalism, Poe assists Ranpo by writing a mystery novel wherein a cast of a thousand people, half of them are murderers. Ranpo uses Poe's book to transport Chūya Nakahara and himself into the world within. There they can battle on an even playing field since the novel contains a world with no abilities. Once the two enter the novel, Poe remarks that even Ranpo would have a difficult time escaping.
