The Spider Fangire, also known by his human identity Ryo Itoya, with his true name being The Capriccio of the Paradise with Light is an Insect Class Fangire with an obsession for the Aso women (Yuri in 1986; Megumi in 2008) and a recurring antagonist in Kamen Rider Kiva.



The Spider Fangire first appears in 1986 at a funeral. Yuri Aso fights him but he eludes her with his invisibility ability. Facing Otoya, the Spider Fangire forced to flee by Jiro.


Taking notice of Yuri's daughter Megumi, Ryo attempts to have her and sends the Sheep Fangire to kidnap her, but the Sheep Fangire soon develops his own obsession with Megumi, leading Ryo to make his own attempt to abduct Megumi. Spider Fangire later makes a deal with the user of the Ixa System, Keisuke Nago, to be left alone to pursue Megumi in order to bring Kiva out into the open. Once he completes his task however Nago drives him off.

Ryo was later tasked by Bishop to awaken Mio as the new Queen, stealing the Ixa Knuckle in the process. However, the Spider Fangire ends up losing the Ixa Knuckle due to his attraction to Megumi. He is eventually destroyed by Mio after she fully awakened as the new Queen of the Fangire Race.
