SCLERA Red

Rui was a boy of short stature and small physical build. His skin was solid white, with red dots appearing at several spots on his face, located above his eyes where his eyebrows are supposed to be, below his left eyelid, ending above his nose, and finally a vertical one running the length of his right cheek. His hair was white and bore resemblance to spider legs. The sclera of his eyes was dark red, while his irises were white, having teal colored eyelashes. Due to holding the position of Lower Rank Five, Rui had the kanji of Lower (下か, Ka?) and daiji for Five (伍ご, Go?) engraved into his left eye, signifying his ranking. His right eye on the other hand had three pupils, with one large one in the center, and two smaller ones to the right and left of the center pupil

He wore a white, oversized kimono that had spider webs etched on the sleeves and the expanse of the hem, which also possessed a loose collar, decorated with the same dot-like markings as his face, and a dark red obi belt around his waist. He also wore a plain, white juban underneath, and was barefoot. His nails bore the same color of his eyelashes.

Rui was a quasi-calm, aloof and somewhat polite individual, rarely raising his voice, and talking to anyone, demon or Demon Slayer, with a reasonable tone and vocabulary, though his low and guttural way of speaking seems to imply repressed anger and annoyance. Despite this stark difference in demeanor when compared to most demons, Rui was actually a disturbed individual who desired the close bonds that a family had and expected family members to perform their own roles. In spite of his yearn to experience a familial bond, his vision of attaining one was incredibly twisted and founded on nothing but fear of him, instilled through repeated abuse on his fellow kin, which he did with unrepentant sadism. To him, "family members" who do not perform their roles as he expected them to (namely to protect Rui unconditionally or follow his every instructions) were worthless and as good as dead.

Well aware of his great power, he was incredibly authoritarian and cruel, having no qualms about abusing others or killing members of his own "family" by stringing them up and leaving them to be burned by the sun when they go against his wishes. Because of his strength, he tended to act almighty and confident, although this arrogance, while hardly unfounded, did not blind him to potential threats to his life.

Because of this, Rui was incredibly sensitive to the subject of family and was furious when Tanjiro pointed out the more than evident toxicity of the bonds forged between his "family." This angered him to the point that he demanded that Tanjiro retract himself and his words and threatened to kill him if he did not comply. This stance contrasted heavily with his desire to have Nezuko for himself as his sister after witnessing her selfless act of shielding Tanjiro from his threads, becoming obsessed with the idea of developing a bond with her, albeit still through fear and torture. This contrarian behavior was further evidence to Rui's delusions, mental insanity, and emotional instability.
