Kamen Rider Kiva

Twenty-two years after the disappearance of his father, Wataru Kurenai lives in an infamous "haunted house" where he is destined as Kamen Rider Kiva to fight life-draining monsters known as the Fangaia, the very race his father fought years ago before his disappearence. Wataru is later joined by a second rider in the series (named Kamen Rider Ikusa) who is part of an organization seeking to destroy the Fangaia menace. The story is split between the actions of Wataru in the present (2008) and his father Otoya in the past (1986), slowly revealing the story behind the Fangaia and Kiva.
