Ryunosuke Katagiri (片桐 龍之介), more commonly known by her nickname Oryo (おりょう), is a kindhearted and timid devil who was framed for the murder of her coworker, Minami, while working at Bar CALM.

History
Oryo was born and raised in a rural part of Kanagawa. Since Oryo's family's devil clan was chased out of the city years ago, they hid away in the countryside. They kept their whereabouts a secret to minimize the chances to be attacked by humans. But when they grew more reclusive, other devils who requested to move into the area were rejected, so a big drop in the number of devil households occurred. This also led to inbreeding occurring. This is why Oryo's family have been weak for generations with short lifespans.

In her adolescence, Oryo got into a fight with a boy and when she punched him, she caused the boy to bleed. Oryo then almost killed the boy by drinking his blood. Ever since then, she has been careful to control her bloodlust.

Appearance
Oryo is an adult trans woman with an average build and height for someone with a masculine body. She has straight, lower-chin length hair which she tucks behind her ears, and middle-parted bangs with two locks framing her face. She has light-colored eyes and slight dark circles under her eyes due to being a non-blood-drinking devil. She occasionally has a little beard and cleft chin.

After the three-month timeskip, her hair has grown longer which she now wears in a ponytail. She also has her bangs slicked back.

After the six-month timeskip (a total of nine months), Oryo begins wearing makeup such as mascara; jewelry such as earrings; and dresses and skirts. When she reappears, she is seen wearing a black dress and her hair is tied into a low bun with her bangs mainly draping over the left side of her face.

Personality
Oryo is a very kind-hearted person. She is helpful and considerate, always trying to help others whatever they are someone she knows or not. When she is at fault for something, she immediately apologizes properly. She is also a bit timid and meek at times, and does not appear very self-confident. She is also careful about controlling her bloodlust and will leave the area as soon as she feels the urge to drink blood. This behavior is linked to an event that happened in her adolescence.

Story
While Tsukasa Taira leaves a grocery store, she is struck by Oryo, who is clearly distressed. After she helps her pick up her groceries, she quickly continues running. Later on, the news reported that a man seen fleeing a crime had still not been found. Yuuki Anzai tells Tsukasa that the murder might be the work of a devil who tried to hide the blood loss by stabbing the body in multiple locations. Yuuki warns her about trusting strangers like the one who ran into her earlier. The two are soon after interrupted by a strange meowing sound from the balcony and find Oryo outside. Yuuki calls in about Oryo and they confirm that she fled but is innocent, as her human manager Okino wanted to frame her for the murder. Yuuki then asks Oryo why she ran if he wasn't guilty, and Oryo explains that when she senses she might lose control, she immediately turns tail and runs. After the questions, the three of them share a hot-pot together, and Takashi Sawazaki and Juliana Lloyd come to pick her up for questioning.

Since her original workplace, Bar CALM, would be an unsafe environment for Oryo, she was hired in Bar Cross instead, which was arranged by Sawazaki. Bar Cross, a members-only devil bar, has a good relationship with Division 5 and is therefore a safe environment for all devils. However, she became unemployed again since the only members of the bar, her manager Kiwako Oe and her co-worker, Wataru Akase were murdered by the CCC since they knew Oryo was a witness for the truth behind the Ikebukuro Incident, so they didn't risk the chance of her telling them.

Oryo continued in hiding from the CCC so she wouldn't be attacked as well. After a while, Oryo stepped out and is currently looking for a new job, but after everything that has happened to her, it has been difficult for her. Oryo considers giving up and going back home since her family has been weak for generations.

Minami
When Oryo was working at Bar CALM, Minami was the only one who treated her with kindness and as a human being despite her being a devil. Oryo was deeply grateful for this and began considering Minami her best friend. Oryo claims that she was the reason she remained uncorrupt and refrained from becoming a true demon. Her death shook and enraged Oryo, and she promised that he would avenge her someday by killing her murderer, Okino.
