Kamen Rider Kiva - 44

"Punk: Back to Father"
In 2008, in the aftermath of Mio's death from her interference between the battle between Saga and Kiva, a devastated Wataru confronts an enraged Taiga until Jiro intervenes, taking him to the Time Door in hopes that the young man may regain his composure by visiting the past to help one there. However, Wataru decides to use this to alter the past by keeping Otoya and Maya apart, negating own his existence and thus save Mio's life. Meanwhile, as a heartbroken Taiga vows that he will kill Wataru for taking Mio from him, Nago takes over the Blue Sky Organization for Shima's sake. Nago later runs into Bishop who sees him as the only remaining threat to the Fangires, defeating the Swallowtail Fangire as Rising Ixa before he escapes.
