Omake (Volume 6)

This is the omake included in the Volume 6.

Part 1
Ranpo suggests to play a game since he is bored and asks the agency for some suggestions. After not getting suggestions, Ranpo suggests to play a and starts off with "Satsujin jiken" (murder case). Yosano responds that he is one and done, implicating that he lost at the round one since no Japanese word begins with the character. However, Kenji still tries to think of a word that starts with "n" and praises Ranpo for being good at the game. Meanwhile, Yosano states that she is done commenting. Kenji then decides to ask for Kunikida thinking that he will know an answer and tries calling him with the help of Fukuzawa teaching him how to use a phone. Ranpo tells Kenji that calling for help is cheating. Yosano just looks at the scene thinking that it might get interesting.

Kunikida picks up the call and Kenji directly asks him what words begin with "nnn". Confused by the question, Kunikida starts to think that the question might be a code and Kenji must be in danger as he's calling him with a secret message only he could decipher. Kunikida tries to brainstorm the meaning behind the question and concludes that Kenji must be talking about the English letter "n" as some of their enemies are from the States and there are no Japanese words stars with "nnn". Kunikida thought of it with a time elapsed of 0.1 sec. Kunikida immediately asks Kenji if his foe's name starts with "N". Hearing the letter "n", Tanizaki wonders how Naomi is doing.

Meanwhile, Chūya Nakahara sneezes.

Part 2
Kyōka approaches Naomi and asks as to why Atsushi's hairstyle is eccentric. Tanizaki replies that both of them don't know either and it's tough to ask about. Naomi expresses that it will be awkward if Atsushi thought that his hairstyle would work.

Kyōka approaches Ranpo next to which the latter doesn't care about it. Yosano apologizes for Ranpo's behavior telling that that's just how Ranpo is. On the other hand, when approached by Kyōka, Dazai suggests to just talk to Atsushi. Atsushi reveals that his fair is no favorite of his and his hairstyle is the result of a prank from the younger kids at the orphanage and he just left it that way since and no one ever pointed it out as odd until he joined the agency.

Tanizaki expresses his pity from afar and offers Atsushi some coffee. Kunikida tells that they will go out for a. Dazai is excited for the meal to which Kunikida replies that he can suck at the charcoal. Dazai expresses his delight for a fine suicide using charcoal. Kyōka offers a snack bar to Atsushi which left Atsushi wondering if he had done something.
