Lore & Background
The text does mention that Kunikida writes plans and objects in his notebook, which he can materialize by ripping out pages, but this is distinct from any item associated with Poe. The source confirms that Ranpo Edogawa relies on 'Ultra Deduction' rather than a supernatural ability or a specific magical journal, though the text does not describe a physical notebook used for deduction.
In Their Own Story
It details Atsushi's transformation into a white tiger and subsequent loss of control, Dazai's nullification abilities, Akutagawa's 'Rashōmon' coat, and Kunikida's materialization of items like guns or swords from his notebook. No scenes depict Poe solving mysteries with a journal.
Reader's Guide
The only guidance available concerns Kunikida's ability: he must write an object in his notebook, understand its mechanism, and rip out the page to materialize it within the size limit of the book itself. This ability is nullified by Dazai upon physical contact.
Did You Know?
- The character designs for Bungo Stray Dogs were developed before the plot lines to prevent characters from becoming too flat.
- Osamu Dazai's ability, No Longer Human, can nullify objects formed by other abilities, such as items created by Kunikida's notebook.
- Ranpo Edogawa is the only Agency member without a true supernatural ability; his 'Ultra Deduction' is a prodigious skill enhanced by glasses given to him by Fukuzawa.
- Akiko Yosano earned the name 'Angel of Death' because soldiers grew exhausted from repeatedly dying and being healed by her in war.
- Atsushi Nakajima's ability, Beast Beneath the Moonlight, references his literary namesake's short story The Moon Over the Mountain.
