The opening stab, your mother murdering you before she dies, isn't a plot twist, it's the show asking if you'll stay when nothing makes sense yet. The animation drowns you in stained glass and gothic shadow so deliberate it feels like watching a fever dream rendered in oil paint. By episode six, the confusion stops being a bug and becomes the point: you're watching someone piece together who they actually are, and the story shifts shape every time Kyosuke gets closer to the truth.
Kyosuke wakes up in a stranger's house with no memory of how he got there. His last clear moment was his mother's blade, and the blood that followed. Now a girl calling herself Runa claims to be his twin sister, and she's showing him something impossible: he's not entirely human anymore. The lunar plague that killed his mother also rewrote his DNA, transforming him into something else entirely. Something that can hunt. Runa isn't alone in her suffering. Her soul was shattered into fragments, scattering pieces of herself across multiple bodies called flicker girls. All of them are marked for death by the Kirihara Group, a shadowy organization with its own horrifying agenda. Kyosuke discovers he's the key to protecting them, though the cost of that protection demands he embraces the alien creature sleeping inside his own flesh. Between fragmented memories, body horror, and enemies closing in from all sides, Kyosuke must choose between his fading humanity and the power necessary to survive.
