Ryōshū is a woman of average height and build, with straight black hair in a bob cut style and sharp red eyes, which at times can be seen glowing. She wears the dark gray and red LCB coat around her shoulders, secured by a small belt that goes over her right arm. Attached to the coat itself is her ID card. She wears black trousers, and her shirt uniform untucked; she foregoes the tie. She is occasionally depicted with a black glove on her left hand. Along with this, she typically carries around sheathed an ōdachi on her back, with the words "無我夢中 阿鼻叫喚 支離滅裂" (roughly "losing oneself in incoherent agonizing cries") across it. The ōdachi's hilt is golden, and decorated with a butterfly pattern. The end of the sheath is wrapped in a red ribbon. The blade is consistently sheathed, as pointed out during the story. In Mirror Worlds, she typically wields a separate weapon, while noticeably still carrying her ōdachi behind her. Ryōshū holds a generally aggressive and overarchingly hostile attitude to anyone that she speaks with or interacts with in her daily life or in the workplace meaning that she often sees the other sinners and all other peers as people with dull, unthinking eyes for being unable to comprehend the true, fundamental nature of works of artistic glory and flaying her enemies apart with glee to witness them in a truly macabre sense of magnificent artful ecstasy in any manner of gore or other gruesome actions, which she regularly conducts with pride and joy, taking great pleasure in both witnessing them and creating them, but 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.
