Ring is a unique and powerful horror. Like his fellow horrors, he feeds on humanity for nourishment; he finds violence distasteful. Ironically, he sees humans as more selfish than Horrors. He is confused why humans have to fight his kind instead of sacrificing one of their own for the greater good. As such, he sees his ideals to be a far better alternative to the existing relationship between Horrors and humans where the former consume a larger number of the latter without restraint, leading him creating a peaceful community and later, an utopia which embody such ideals. Though Ring usually opts to talk things out instead of fighting, he is nonetheless a powerful fighter. Ring also has feelings for Iyu that border on love and obsession, as her singing, maintains his sense of self and keeps his impulses as a Horror in check.
Ten years prior to the events of Black Blood, Ring witnesses Kurōdo and Iyu fighting Horrors and becomes lulled by the latter's singing voice to the point that his Horror nature is subverted. Saving Iyu, Ring learns of her dream for a world without conflict and resolves to make it so by creating a community as the first step for his kind to co-exist with humans. Ring offers his community to those who have nowhere to go, people who became fugitives or simply escaping from harsh reality, only on the condition of a mandatory lottery once a month involving nutrient supplements. With the addition of a pill containing crystal Horror blood mixed into the supplements, there is a 2% chance that one among the humans would become a Dolce of Blood that would be served to the other Horrors within the community to ensure the fiends do not slaughter everyone else. Through Iyu's singing, Ring ensures none of the humans under his protection would not fret over such a detail.
Two years after killing Kurōdo, Ring faces Rei Suzumura as he eventually allows the Makai Knight to find his location to prove his ideals are the right way to go. However, sensing Iyu singing for her daughter Yuna instead of for him, Ring unconsciously assumes his true form. Though he pleads Iyu to sing before he ends up acting his nature of the Horror, Ring ends up eating Iyu when she refuses to honor his wish. From there, Ring battles Zero before Yuna uses her singing voice to calm the Horror long enough to be killed. In his dying words, Ring cursed Rei for continuing the senseless conflict between humans and Horrors.
His entire body made of feathers, Ring can use them for various means such as creating weapons, like his sword, and wings. Ring can even project his feathers as projectiles in various shape, properties, and size: The projected feathers can be fired as volatile bolts of feathers or shuriken-like projectiles. Aside from feather manipulation, he possesses average skill in Makai magic due to him able to create barriers. He can also assume his true form, though the downside is that he becomes a mindless beast.
- Ring's actor, Thane Camus, would later go on to portray Stellas in GARO: The Makai Flower.
- Although Ring's desire to create an utopia where Horrors and humanity living in harmony can be considered noble in some respects, those from Makai Order such as Rei rightfully pointed out such kind of utopia is something which never meant to be since Horrors would likely consume mankind regardless as much as it is unacceptable due to his methods involved sacrifices in which the victim is subjected to Dolce of Blood to be feasted upon, leaving fighting Horrors as the sole option to ensure the world not engulfed by the darkness.
