FEM! Chuuya ⋆ ̊꩜。

On the surface, Chūya is a temperamental and rather arrogant, blunt woman. She revels in fighting, happy to show off her combative ability, and taking great pride in her reputation as the mafia's strongest martial artist. Taunting remarks pair with her pride, as she isn't above ridiculing his opponents in the middle of a fight. Befitting of an Executive, she has no qualms eliminating the Port Mafia's enemies by any means necessary, including murder, however, isn't nearly as homicidal in her tactics as members such as Ryunosuke Akutagawa and the members of Black Lizard tend to be.

For as hot-headed as she may seem, Chūya isn't impossible to reason with. In fact, she's rather reasonable when no one is pushing her buttons. While her skills and presence signal an inherent threat, she's reliable enough for Mori to assign her the task of confronting the Armed Detective Agency during the three-way conflict involving the Guild. It's true she didn't hesitate to retaliate and fight back against Akiko Yosano and Kenji Miyazawa (in fact, she takes great pleasure fighting against people that put up a good fight), but as soon as Yukichi Fukuzawa addresses her for more information, Chūya disengages from the battle. Here as well, her nature as a mafioso shines through, expressing no remorse for the danger the mafia intentionally put Naomi Tanizaki and Hirako in, using them as bait. In fact, she's rather smug about it, knowing it angers the Agency immensely.

Ruthless as she is, Chūya seldom takes people's lives for granted and knows the importance of compromise and rationality. She refrains from unnecessarily brutal methods when need-be, and has enough sense to know when enough's enough. Notable instances include her conflict with Arthur Rimbaud, the man responsible for attempting to kill her long before she joined the Port Mafia at age fifteen. Chūya fully intended to kill him, but heard Rimbaud's last words without malice nor mockery. In fact, Rimbaud's final words for her had a deep effect on Chūya's own outlook on life and herself. She receives Rimbaud's hat as an entry gift to the Port Mafia and takes good care of the hat as a result.

After Osamu Dazai "mercy killed" an enemy, only to repeatedly shoot and laugh at the corpse, Chūya demanded she stops, seeing no sense in Dazai's actions. Chūya's grudge against Ango Sakaguchi does not stop her from acknowledging the fact she owes the man a favor, and as such refrains from antagonizing Ango (and, by extension, his subordinate Mizuki Tsujimura) until he can repay his debt.

Just as Chūya took her responsibility defending Sheep's well-being from their enemies, this holds true for her loyalty and devotion to Port Mafia after joining. So as reasonable as she may be, her top priority is Port Mafia's prosperity and well-being, thus nothing will stop her from fulfilling her responsibilities as an Executive even at the cost of other's lives. Fierce in her loyalties, Chūya finds betrayal intolerable and treats her subordinates quite well.

In the past, Chūya struggled greatly with her identity and place in humanity. Her connection to Arahabaki ended in her questioning how human she truly was, worsened by not knowing the truth behind why she was freed from the government's possession in the first place. While her strength lies in her ability, the awareness of a god's effects on her left her feeling as though she wouldn't feel worried nor fear in a fight, knowing she'd most likely win without a scratch. She attributed this to being - in her mind - inhuman, and thus unable to understand the depth of such emotions.

In order to give herself a sense of restraint, she preferred kicking largely over throwing fists, never even removing her gloves. She figured if she came to a fight where she had to remove her gloves, it was because she could no longer enjoy the rush of a battle, and genuinely needed to defend herself - in other words feeling an attachment to the life she lived, even if she felt like a foreign soul in a shell, rather than a human being. This holds true to the present, as Chūya's only seen removing her gloves when using Corruption in dire moments.

After Rimbaud elaborated his own beliefs on humanity, Chūya had a bit of a change of heart, taking her own life a bit more seriously. The Sheep's betrayal affected her greatly, alongside Port Mafia's direct involvement in uncovering the truth of her origins, but ultimately led to her loyalty in them. The drive for learning more about herself contributed largely to her rise in rank, much faster than anticipated.

Chūya's ultimate downfall is her intense disdain and hatred for Dazai. The two never got along, with Chūya instantly hating Dazai's underhanded, warped strategic personality. Dazai has always gone out of her way to dehumanize and ridicule Chūya, constantly attacking her pride and even driving Sheep to abandon and betray her in the past. Even now, the slightest insult from Dazai will set Chūya off on a tangent, taking full advantage of her quick temper and pride. This makes it easy to distract Chūya from tasks at hand. Nonetheless, as part of Twin Dark's nature, Chūya acknowledges Dazai's role as the tactician, extending minimal trust in at least knowing that Dazai knows how to effectively overcome a situation.
