Atsushi Nakajima’s character is based on a short story by an early 20th century Japanese author. The author, whose name is similar to Atsushi’s, created a story called “The Tiger Man,” in which an unfulfilled bureaucrat turns into a tiger after hearing a voice in the forest. Atsushi’s name is a tribute to this author and his work.
In Bungou Stray Dogs, Atsushi’s character borrows elements from the original story, such as his ability to turn into a tiger. However, the series expands on Atsushi’s story to create a unique and compelling protagonist with his own backstory, challenges, and growth.
