Ritsuka is summoned to the student council room again, where Urie, Mage, and Shiki attempt to make advances on her before Rem arrives. He informs her that the police have tracked the signal from her mother's phone to the house of her grandfather, a student of magic and magical lore. When Ritsuka mentions that her grandfather's research and materials are still at his house, Rem immediately takes her there. Upon arriving at the house, they find it ransacked and they both get locked inside. A fire starts, and when Ritsuka goes to get the extinguisher she is again attacked by the people who kidnapped her mother. Rem saves her and tells her to run, then confronts the attackers. He informs them that Ritsuska is his before using magic to turn them into dust. Later that evening, when they arrive back at Rem's house, they find Ritsuka's brother Lindo waiting for them.
