Atsushi Nakajima

Atsushi Nakajima (中島 敦) is the main protagonist of Bungo Stray Dogs and a member of the Armed Detective Company.

Appearance
Atsushi has white blond hair, pale skin, and purple and yellow eyes - purple towards the centre of the iris, with a yellow ring around the outside. His hair is short and swept forward in loose spikes with a lock left long on the right side of his face. He is of average height with a slim build.

At the beginning of the series, he was wearing rags and one glove on his left hand. After he joins the Armed Detective Company, he wears a white button up with the sleeves pushed to his elbows, a loose black tie, black pants, fingerless gloves, and a suspenders/belt combo with a long stretch of the belt dangling loose from the buckle.

Personality
Atsushi has severely low self-esteem due to his upbringing. He has a major complex about his worth as a person, as such he reacts negatively to people who judge others as unworthy. He has a strong sense of morality, as seen through his interactions with Kyouka. Generally flighty and unsure of himself, his will hardens in tough situations, and he becomes steadfast and reliable.

Ability
Moonlight Beast (月下獣): Atsushi has the ability to transform into a white tiger. At first, he doesn't seem to have much control over the transformation, likely due to the fact, or caused by, his unawareness of his state as an Ability user. As the series progresses, he gains more control over his transformations - as shown during his second fight with Akutagawa, when he breaks the transformation on his arms to escape.

Atsushi has shown several varying states of transformation, which range from a rather large full tiger form, to just slit pupils and tiger stripes on his face. He can transform and manifest various tiger body parts at will, such as tiger forearms with claws, or a tiger tail.

Also notable is that Atsushi's ability has extreme regenerative powers capable of healing bisection and amputation almost instantly.

Someone from the underground has put out a 7 billion yen bounty for him with the Mafia - it isn't clear why at this point, but his Ability seems a likely reason.

Background
Not much is known about Atsushi's background thus far. He grew up in an orphanage, where he was repeatedly told he was worthless and a nuisance.

Shortly before the series begins, Atsushi was kicked out of the orphanage because, although he was unaware of it at the time, he was transforming into a white tiger under the moonlight and causing chaos.

Trivia

 * He and several other characters made an appearance in the mobile game Love Heaven as a limited time character.
