Suruga thinks the Devil is about her, so she hunts it like an obsession, but the show is actually watching her convince herself that her worst fear is someone else's problem. Five episodes to dismantle a girl who built her entire identity around being special in the worst way possible. By the end, you're not solving the mystery, you're watching her finally stop running from what she already knows about herself.
Suruga Kanbaru's life feels hollow. With Araragi and Senjougahara gone, she's alone at Naoetsu Private High School, still carrying the weight of the Monkey's Paw that granted her wishes years ago. When whispers of a mysterious "Devil" start circulating, someone who solves problems through supernatural means, Suruga's curiosity turns personal. She needs to know if this legend involves her. The trail leads to Rouka Numachi, a former basketball rival now confined to a wheelchair. Rouka runs an informal advice service, offering desperate people exactly what they want to hear. She collects their misfortunes like trophies, savoring the hope she manufactures before letting it crumble. What begins as Suruga's simple investigation becomes something far more complicated when she recognizes in Rouka a twisted reflection of herself: two girls shaped by injury and obsession, each carrying supernatural baggage. Their confrontation isn't about heroes and villains. It's about recognizing how easily good intentions curdle into something darker, and whether connection can exist between people built on lies.
