After Azuna's death, Lindo takes Ritsuka to the Exorcist Association for protection. Meanwhile, Urie, Mage and Shiki realise that Ritsuka was the grimoire all along and they start to search for her. The Exorcist Association then betray Lindo's trust, by deciding to kill Ritsuka in order to get rid of the grimoire, but Lindo interferes. They also reveal to Ritsuka that her brother is actually a 'dhamphir'; half-human, half-vampire. Lindo escapes with his sister and they hide in a Japanese shrine while Urie, Mage and Shiki hold off their pursuers. While hiding, Lindo reveals to Ritsuka that they are not siblings; but cousins. His father was a vampire, and his real mother is actually their deceased maternal aunt, Marta. He then confesses to Ristuka that he is in-love with her and attempts to kiss her, only to be interrupted when Rem arrives. Assuming that Rem has come to obtain the grimoire, he and Rem decide to settle their matters once and for all in a battle using their powers. Rem injures Lindo and is about to finish him off until Ritsuka yells at him to stop. She tells Rem that she can no longer stand watching her close ones get hurt and killed just because he wants the grimoire. When Rem doesn't say anything, Ritsuka yells that she hates him and Lindo repels Rem with his magic. Rem leaves heartbroken while Ritsuka takes Lindo to Shikō Academy's infirmary to treat his wounds. She then decides to forget her feelings for Rem so she can protect her family. Meanwhile, Jek visits his master, Lord Nesta to tell him about the grimoire.
