The Horse Fangire, also known by his human identity Kaoru Tsugami, is a Fangire from the Beast subclass and an antagonist in Kamen Rider Kiva, later appearing in Kamen Rider Den-O & Kiva: Climax Deka.
He is the first Fangire to appear in Kamen Rider Kiva.
Posing as an executive of a company, the Horse Fangire fed on the energy of his two secretaries until he was confronted by Yuri Aso. However, Otoya Kurenai's interference allows him to escape.
The Horse Fangire resurfaces during the events of Climax Deka, assuming the identity of robbers and accompanying the Pink Rabbit Imagin in fighting Den-O and the Taros. He is destroyed by Den-O Sword Form, but his soul escapes and is later restored his body. He then assumes the identity of a teen model agent to go after Megumi Aso, but Megumi instead tricks the Horse Fangire into being destroyed by Kiva and sealed in Castle Doran.
