Curtain Raising: Kiva's Identity

Curtain Raising: Kiva's Identity (開演・キバの正体) is the thirtieth episode of Kamen Rider Kiva.

Plot
In 1986, the Rook nearly kills Yuri when Jiro intervenes to finish their game, mocking the Rook with a new pair of sunglasses before Yuri is taken the hospital. Otoya visits her with flowers and advises her not to get back to work so quickly, but she remains adamant as she cannot rest until she avenges her mother. After Otoya & Jiro trick her to go to Ryokuchi Park,with Riki acting as a decoy Rook, Otoya tracks down the Rook and summons Jiro, Ramon, and Riki to battle, becoming Ixa as the trio assume their true forms. Using sunglasses as bait, Ixa and the Arms Monsters fight the Lion Fangire as Yuri arrives, with the Rook winning the game.

In 2008, after the Warthog Fangire walks off after defeating Kiva, vowing to kill him once he becomes the King, Wataru is depressed that Mio is not answering his calls, due to Shizuka's meddling. Things get worse as his friendship with Kengo also gets strained when Wataru learned that Kengo could never play guitar again and hid the truth until Kengo left. Nago decides to offer his aid to excuse to investigate his thoughts on Wataru, as Shizuka realizes the consequences of her actions, setting Wataru & Mio on a date. While this all occurred, after Megumi is wounded from her own fight with Rook, Mitsuhide pleas his sister to leave the Fangire Hunters with Megumi refusing as she vows to finish what her mother started. However, Mitsuhide goes over his sister's head to have Shima relieve her of her duties. But refusing to let that stop her, Megumi poses as an assistant to Red Man, a potential Fangire target. Though the Rook arrived to offer his aid, he knocked Megumi out as Aberu arrives to kill Red Man, resulting with a battle between the two Fangires. Nago arrives to intervene, becoming Rising Ixa until Wataru shows up to even the odds. While Nago deals with Aberu, Wataru battles the Rook in Emperor Form. But during the fight, the Fangires take their leave as Nago witnesses Kiva regress back to Wataru, with the Bishop showing interest in the revelation.
