Kurumi recalls an upperclassman that she had a crush on before he became a zombie. As Kurumi scouts the school for any wandering zombies, she is shocked to see one of them was once the upperclassman's girlfriend, which she is forced to kill. Later, Yuki suggests that everyone go on a test of courage through the school, which the others use as a motive to obtain supplies. While exploring the library, Yuki comes close to encountering a zombie, but is calmed down by Megumi and encouraged to hide while the others lure it away and finish it off, with Yuki remaining unaware.
