At the beginning of the game she is seen singing Out of Darkness at an Order of the Sword gathering, occasionally glancing at the empty pew where Nero is supposed to be.
Nero appears just before the song ends, and he hands her a small gift as she comes to sit beside him while Sanctus explains the history of Sparda's rebellion against Mundus and his demon brethren.
The love between Kyrie and Nero seems to have started before the events of Devil May Cry 4, but their love is used as a major plot point on several occasions during the game.
The madman threatens to kill her if he advances further, but Nero tosses the Yamato to the false prophet to distract him, then slams him into a wall with the Devil Bringer.Upon seeing me in person for the first time, my dates told me that I look just like my photos. Born and raised in Fortuna where she spent most of her days, she is the younger sister of the leader of the Order of the Sword's Holy Knights, Credo, and songstress for the Festival of the Sword.As Dante approaches her brother Credo, Kyrie is knocked down and cowers in fear before Nero comes to her rescue.Credo orders Nero to hold off the assassin while he takes Kyrie to safety and fetches help.
With a swift cut from the Yamato, Nero frees Kyrie and impales Sanctus, killing him.
