Plot
In 1986, Maya takes advantage of Otoya's memory loss by pretending to be Yuri, ordering the Rook to halt his Game out of her curiosity for human love. Later, after playing his violin for Maya, Otoya remembers his promise to Yuri as he makes his way to Saihama to takes a dive in the sea to fetch the ring of Yuri's mother for her. By that time, Yuri arrives to see Maya who asks her the meaning of "love", with Yuri's answering before seeing Otoya and saving him from nearly drowning, regaining his memories from the near-death experience. As Otoya gives Yuri her mother's ring, Maya had taken her leave with a red rose on Otoya's violin and increase of curiosity about human love.

In 2008, Wataru is worried about Mio's whereabouts, as she is unable to willingly accept being the Queen to the Bishop's dismay as he kills a target Fangire traitor and his human girlfriend to Mio's dismay as a warning to her. Turning to Wataru for help, Mio apologizes for running off before she leaves without goodbye. She is then ambushed by Ryo with the Bishop watching in hopes Mio will awaken as the new Queen. However, Nago arrives to reclaim the Ixa system as Ryo uses it against him. But by taking advantage of the Fangire's obsession with her, Megumi lowers Ryo's guard down so she can knock the Ixa Knuckle back to Nago. Though Ryo escapes Ixa, he makes an attempt to kill Mio for ruining his love life, attacking Wataru when he intervenes before accidentally provoking Mio into a full-awakening as the new Queen. Though the Spider Fangire attempts to flee her, Kiva blocks his escape in Emperor Form using the Garulu Saber to wound him before Mio personally kills Ryo herself later. As for Nago, in spite of his earlier decision, Shima decides to let him keep the Ixa Knuckle and the eventual upgrade that goes with it when Nago fakes admitting his flaws.
