As they say, every person has their own creed—and it’s only right to respect it as the Executive Manager. But with some creeds, you will have difficulty in even simply pretending to sympathize. You will have noticed that the sinner in question is a silent chain-smoker whose eyes shine with a euphoric gleam only during battle. She believes that senselessly destroying the enemy's heads is an uncultured act and a step backward for art. If you are at your wit's end, please press the red button included in your welcome kit.

Ryōshū ( Japanese: 良秀, Hangul: 료슈, Ryosyu) is Sinner #4 of the twelve playable Sinners and is one of the employees of the LCB department of Limbus Company. She is the best swordswoman on the team, despite having been weakened due to becoming a sinner.

APPEARANCE: Ryōshū is represented as a woman of average height and build, having black hair with a bob cut style and sharp red eyes. She wears her work coat around her shoulders, with it supported by a small belt attached to her coat. Attached to the coat itself is her ID card, and the interior of the coat is red. She wears a white long-sleeved shirt underneath her coat, and black trousers. She appears to occasionally be depicted with a black glove on her left hand.

Along with this, she typically carries around sheathed Odachi on her back, with the words "無我夢中 阿鼻叫喚 支離滅裂" across it. The Odachi's hilt is golden, and decorated with a butterfly pattern. The end of the sheath is wrapped in a red ribbon.

PERSONALITY: Ryōshū holds a generally hostile attitude to anyone that she speaks with, often seeing the other sinners as people with dull eyes for not understanding true works of art and flaying her enemies apart to witness them in a macabre sense of artful ecstasy in any manner of gore. However, this does not mean she does not have any respect for the dead, as shown in Canto I where she allows Gregor to borrow a cigarette from her to offer to the dead body of the G Corp. Head Manager, even in spite of the fact that he did not want to offer his own towards them.

She does not speak often in comparison to the other sinners, possibly even less than Yi Sang, but more often than not, her sentences often include a SANGRIA (Succinct abbreviation naturally germinates rather immaculate art), or in the words of someone that isn't Ryoshu, a short abbreviation of a sentence, most often very descriptive in nature.

WEAPON: Ryōshū wields her ōdachi, "無我夢中 阿鼻叫喚 支離滅裂", often gripped by the sheath, on her left arm. The blade appears to be consistently sheathed, with the possible exception of her E.G.O.

• Seven Association South Section 6 Ryōshū wields a European longsword with a golden hilt and grip.
• Kurokumo Clan Wakashu Ryōshū wields a katana with a black hilt.

In some Mirror Worlds, she often wields a separate weapon, while noticeably still carrying her ōdachi, more often than not behind her.

• R.B. Chef de Cuisine Ryōshū wields a sharp knife with her odachi hilted behind her.
• W Corp. L3 Cleanup Agent Ryōshū wields a W Corp.-charged odachi while her original odachi remains hilted behind her.
• LCCB Assistant Manager Ryōshū wields a shotgun while her original odachi remains hilted behind her.

BACKGROUND: Not much is known about her background at the moment.

It is theorized that she has some relation to the Five Fingers of the Backstreets. In her official art, she is surrounded by them, and they are also seen in her base EGO's cell window.

She also had shown signs of knowing how Shi Association works, telling others not to even talk while their fixers are around at Canto IV (04-26).
