Hatsumi Inumaki

Hatsumi Inumaki (井木はつみ, Inumaki Hatsumi) is a member of the Armed Detective Agency and was a former member of the city's worst underworld organization, the Port Mafia. She possesses the ability Infinite Void.

Appearance
Hatsumi is a young woman with tall stature. She has very light skin, long gray hair styled into two ponytails that are tied with black ribbons and blue petal-shaped hair accessories, with two shoulder-length braids on both sides of her cheeks. Her eyes are blue and she wears peach-colored lip gloss.

For her attire, she wears a black, high-collared, cropped, long-sleeved jacket, decorated with white wavy lines, mint flowers, and pink hearts, paired up with matching plain black skirt ant knee-high boots. She also sports black overall straps, and a bolo tie holding a green pendant with a wing symbol.

Personality
Hatsumi is a caring individual with an unshakable character. She is a loyal person, with a logical and laid-back demeanor especially towards her friends. Even as a member of the Port Mafia, she refuses to kill people and despises the organization itself. She is only kept alive due to the Port Mafia leader's desire to control her because of her exceptional ability. In the Armed Detective Agency, she is shown to be nonchalant and playful with the members, especially with Dazai whom she shares similarities to personality-wise, to the frequent dismay of Doppo Kunikida.

She is also confident with her abilities, though she does not believe that she is invincible unlike what most people say. According to Dazai, Hatsumi possesses natural talent over controlling her ability and was far superior than Akutagawa which she denies. She believes that the world is unfair, though as a detective, she is to ensure that kind people are given more chances to live, and admires Atsushi Nakajima's actions to save people he deems good, no matter what people say.

She is also quite a secretive person that doesn't like to talk about her past, as shown when Ranpo complains that Hatsumi hardly tells them anything about herself.

Ability
Infinite Void (無限ボイド, Mugen Boid, literally "Black Hole") allows Hatsumi to attract and repel objects within a 10 meter distance from herself. She is also able to attract herself to other objects, causing a sense of teleportation or blinding bursts of speed. Her ability is not always active and can be dispelled anytime.

Background
According to Dazai, Hatsumi grew up in an orphanage and was adopted by a rich family who was later killed by the Port Mafia to obtain Hatsumi as an asset to the organization. It is later revealed that Dazai and Hatsumi are distant relatives.

Quotes
(To Ryunosuke Akutagawa) "People with formidable special abilities, always think that things would go as they plan. That's going to be your downfall."

(To Atsushi Nakajima) "One who smiles, rather than rages, is much stronger."
