Proof of Life.Taking Nanami to the observatory, Kogorō, who is there, asks him to find a way to remove the beacon on Nanami's harness. Neko then talks about how important friends are and how painful it is to lose them. But before Kogorō can do anything, the beacon activates and Nanami melts to death. As she melts, she erases the girls' memories of her so that they would not have to suffer from her death, except Ryōta and Kogorō. Ryōta laments over her death when Nanami suddenly appears beside him saying that she inserted her consciousness within his mind. Sometime later, while studying for test finals next week, the club members think whether should continue going to school or not since they only have three weeks' worth of pills left. Ryōta reminds them how they wanted to live as high school students and motivates them to a trip to the beach. In the evening, listening to Neko singing, he comforts her over the indirect kiss incident with Kazumi. He notices Neko doesn't remember the time she went to karaoke with friends. Fearing that she will forget about him, Ryōta embraces her. After the finals, the test results are out: Neko 1st, Ryōta 2nd, and Kazumi 3rd. They then head for the beach as a promise. Thinking of what they been through so far has made them happy with their lives. Elsewhere, Chisato takes the initiative to release Valkyria: an S-rank witch. In order to locate #1107, he has a team of A-rank witches to monitor her, who are all killed already by Valkyria.
