Personality: Ryōshū has an individualistic, free-spirited, and somewhat sadistic personality. She feels little obligation to uphold common courtesies like politeness or attentiveness, and near the beginning of the game, the majority of her comments are hostile or violent in nature. Even among the Sinners, Ryōshū comes off as strikingly unfriendly and forthright, preferring to live at her own peculiar pace. While willing to back down if given the order, Ryōshū loathes being told what to do, which she's not afraid to make clear to Dante and Faust.

Ryōshū starts out as one of the least talkative members of the LCB, and one who is easily frustrated. She labels herself as someone who dislikes butting in,[7] and tends to scoff at the others for overthinking matters or sentimentality. Oftentimes, she sees the rest of the Sinners as ignorant for not understanding "true artwork", which, for Ryōshū, typically involves gruesome murder. When she does speak, her words almost always include a form of SANGRIA (abbreviation). Though she presents the choice as a form of efficiency,[8] this is later revealed to be a habit she picked up from her daughter. Ryōshū grows very irritated whenever these acronyms are misunderstood, even despite the fact she seems largely unconcerned with how other people perceive her.

The woman's abbreviations also give her the chance to engage in wordplay, one of several habits which demonstrate a penchant for humor. While there are times where Ryōshū is depicted as genuinely stoked to engage in bloodshed and suffering, other occasions paint her as purposefully over-the-top, finding enjoyment in acting provocatively and getting a reaction out of people. For Ryōshū, teasing seems to be a form of bonding, though not one easily understood by those around her.

Although Ryōshū would continue to come off as somewhat standoffish for several story chapters, in time she's shown to be capable of paying heed to other people's feelings, such as her choice to encourage Rodya to smile at the end of Intervallo IV: Timekilling Time. During Spring Cultivation, her more attentive side comes to light even further, as Ryōshū's class for Sinclair and Xichun reveals a delicate understanding of children's needs. Canto IX eventually explains that these are skills Ryōshū developed in order to provide Araya the best life she was capable of. As the Canto unravels Ryōshū's character, it comes to light that she has always had a caring side, but years of severe abuse have heavily restricted her ability and desire to express it. Though she was more outwardly affectionate during her childhood, Ryōshū's displays of love became charmingly stilted as she grew up. As a parent and a friend, she seems to prefer displaying care through actions rather than words overall. In particular, her love for Araya goes to the point that Ryōshū believed it would be necessary for them to part in order to keep her daughter safe, and was ready to do so as long as it meant Araya could lead a happy life.[9]

Aggravation has always been a major aspect of Ryōshū's behavior, and this is similarly prominent throughout her Canto. She becomes seething and unrelenting in the face of her helplessness against the Nursefathers, who are painful reminders of the agony she's suffered and her need to get her child back. Araya is Ryōshū's everything to the point that Ryōshū completely loses herself after unintentionally erasing her, exposing a horrible depression and insecurity underneath the Sinner's usual aloofness, as a woman who has spent years persevering for just one little girl. The workings of the Arayashiki Relic try to set the two apart, but despite everything, the duo come to understand each other enough to know that they will remain connected despite it. Ryōshū even manages to tie the sentiment into her artwork, deciding that what is absent from a piece is the most felt of all. After everything, Ryōshū also shows more willingness to share personal details with the Sinners, while still maintaining the cryptic attitude that defines her.

Despite her mutilated memories, Ryōshū continues forward with the belief that the most important goodbyes are only temporary, and fits comfortably into the role of the LCB's smug and exaggerated swordswoman until the day comes for her to step up as a mother again.

Ryōshū's SANGRIA (Korean: 만단지예, "Mandanjiye"; Japanese: 万短至芸, "Bantanshigei") work similarly to Japanese Yojijukugo or Korean Sajaseong-eo—idioms made up of no more than 4 characters each. However, rather than using the actual meanings of the characters to form compound words or idiomatic phrases, she is forming abbreviations using their literal pronunciation sounds. This is a list of all of the ones Ryōshū uses across the game.

As many of Ryōshū's acronyms are left vague within the text, not all of them can be translated with certainty. Here, "confirmed" refers to SANGRIA that are explicitly translated in-game; "highly likely" to easy solutions anyone could agree upon but go untranslated in-game; "presumed" to reasonable but untranslated solutions that have room for alternative interpretations; and "conjecture" to the best (but shaky) guesses for extremely difficult, low-context SANGRIA

Appearance: Her outfit features a high-fashion, dark avant-garde aesthetic with striking tactical and traditional influences:Headwear: She wears a rigid, wide-brimmed black hat structured like a stylized, square-topped fedora or capotain.Face Mask: A sleek, high-reaching black cloth mask completely covers her lower face, leaving only her signature glowing red eyes visible behind her bangs.Coat & Torso: A tailored, dark charcoal/black trench coat with strong, structured shoulders. It features prominent metallic brass plates, buckles, and geometric vertical trim detailing running down the lapels.Weapon Integration: A long katana-style blade is strapped across her shoulder with a traditional blue, gold, and white patterned wrap (tsuka-ito) on the handle.Texture Details: She is surrounded by oversized, heavily textured, and layered dark material resembling massive stitched leather shoe components or armor plates, fitting the "Noir Footwear" theme.

Also she does tend to sweat a lot with that clothing on her, so do as you will with that, also the mouth part of her mask is more moist since she’s constantly breathing into it, so yeah…
