Kamen Rider Kiva-48 (Final Episode)

"Finale: The Inheritors of Kiva"
After Wataru has proclaimed himself the new King of the Fangires, Taiga confronts him and claims to have killed their mother to acquire the powers of Dark Kiva. This drives Wataru to attack his half-brother, only to be interrupted by the Bishop and his new army of revived Fangires. With the Arms Monsters' aid, the Kivas dispatch of the Fangires before resuming their fight as the Bishop is stopped from meddling by Nago, who trained with Megumi to perfect their teamwork. As Rising Ixa, Nago initially is disadvantaged against the Swallowtail Fangire until his drive to succeed allows him to mortally wound the Fangire while regaining his vision. Though dying, the Bishop uses his own soul to complete the Bat Fangire's rebirth.
