Rui Ayaki

Rui is a quasi-calm, aloof, and somewhat polite individual and demon, 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. Every time he spoke with Demon Slayers(like Tanjiro Kamado) during their initial duel, he remained somewhat civil in speech.

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. Despite his yearning 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 of his fellow kin, which he did with unrepentant sadism. To him, "family members" who did not perform their roles as he expected them to (namely to protect Rui unconditionally or follow his every instruction) 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 his "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. Furthermore, he seemed to be fully aware that all his efforts to create a "family" and feel a bond have been in vain.

Because of this, Rui was incredibly sensitive to the subject of family.

As one of the Twelve Kizuki, Rui was one of the strongest demons in existence. This strength easily surpassed that of most other demons, since he was easily able to conquer and cohere numerous demons of Mount Natagumo and force them to work for him and become members of his family.

Rui possessed a body that was incredibly durable and hard to cut, easily far surpassing the hardness of lesser demons.

Rui had displayed incredible physical strength, as well as unlimited stamina and endurance.

Rui possessed an aura that was most noted to make the air feel thick and heavy with a mere gaze.

Rui possessed the ability to share his power or even his appearance with other demons if they drank his blood. The process was extremely painful for the demon, even requiring their face to be torn off to complete the transfer. Once completed, the demon will gain an appearance similar to Rui's, with pale white skin and red markings. Sometimes, they may also gain spider-like characteristics.

Rui's Blood Demon Art allowed him to create thin threads indiscernible from string from his own flesh and manipulate them however he pleased. He typically extended the threads from his fingertips like a puppet master. Due to his own body's durability, the threads Rui manipulates were extremely durable and sharp, being capable of cutting as well as Nichiren Swords and blocking strikes from them as well. Rui can further amplify their strength and durability by infusing his blood through them, giving them a blood-red color.

Rui displayed terrifying proficiency in utilizing his threads for combat purposes, making use of the environment to spawn a barrage of slashing attacks or manifest unavoidable web techniques to trap and slice his opponents into pieces.
