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 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 calls him out on his stoic, icy front before yelling that she hates him, despises him and never wants to see him again. Rem leaves heartbroken after Lindo repels him with his magic. Ritsuka then takes Lindo to Shikō Academy's infirmary to treat his wounds and while there she decides to forget her feelings for Rem so she can protect her family. Meanwhile, Jek visits his master, Lord Nesta to inform him that he has found the grimoire.
