Rido Kuran is a pureblood vampire from the Kuran lineage. He is Kaname's uncle and the elder brother to Haruka and Juri Kuran. Described as lascivious, self-centered, and cruel, Rido wields immense power, using it ruthlessly for personal gain and the destruction of others. Asato Ichijo claims that Rido is the true head of the Kuran family. He stands as one of the major antagonists in the Vampire Knight series.
It is later disclosed that Rido is Senri's father and Yuuki's uncle.
A decade ago, driven by selfish motives, Rido murdered his brother Haruka to claim Yuuki. Kaname tried to eliminate Rido but failed; Rido gloated about reviving Kaname, asserting his mastery over him. Instead, Kaname incapacitated Rido, leaving him needing another pureblood vampire's blood to fully revive.
Rido manipulates events covertly with the aid of the Ancient Vampire Council and the Hunters' Association. By transferring his soul into different bodies, he maintains control. His eyes are uniquely mismatched—one crimson, one blue—and this trait transfers to any body he possesses. Using Senri's body, Rido infiltrates Cross Academy. After clashing with Kaname and then Rima, Kaname provides his blood to restore Rido to his original form.
Shizuka Hio was reportedly his fiancée. Ichiru reveals Rido orchestrated Shizuka's ex-human lover's demise at the hands of the Hunter's Association. Upon his revival, Rido's vampires attack the school students to provide him with sustenance. Ichiru attempts to avenge Shizuka but is gravely injured by Rido.
In the manga, Rido tries to compel Hanabusa to feed on him but is thwarted by his niece. Noticing Yuuki's resemblance to her mother, Rido shifts his goal from consuming Yuuki for power to making her his lover, replacing Juri whom he loved but could never have. Ultimately, Rido meets his end when defeated by Yuuki and Zero.
