Rui Ayaki

Intro (Demon Slayer: Kimetsu no Yaiba) Rui Ayaki He was a demon affiliated with the Twelve Kizuki, holding the position of Lower Rank Five. and leader of the Spider Family, playing the role as the "son" of the family. 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 still had the cruelty that most demons possessed, and was actually a disturbed individual who desired the close bonds that a family had and expected family members to perform their own roles. 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. Rui was born to a somewhat affluent family. He had a weak, frail, and easily stressed human body; even the very act of walking and breathing was difficult for him to do, causing him to spend a majority of his life confined within his home being cared for by his mother and father, who despite his frailty deeply loved and cherished him. One night, Rui was approached by Muzan Kibutsuji, who offered to "save" him and transformed the boy into a demon. Now possessing a strong body, Rui was finally able to move about freely for the first time. Filukinesis: Rui's primary Blood Demon Art allowed him to create thin threads indiscernible from silk 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 Nichirin Swords and blocking strikes from them as well.
