Kurumi's fucking dead, isn't she? She doesn't feel the cold water, every time she touches Yuki she says her hands are cold. She's fuckin dead and reanimated from that zombie bite, but the cure stopped her from going insane. Maybe she's been dosing herself with the cure ever since then. What happens when she runs out? The same thing that happened to radio girl when she ran out, I bet. FUUUUUUUUUUUUUUUUUUUUUUCK!
