The three helpers thought they'd finally escaped the wheel. Kikuri drags them back anyway. What makes this burn is that it's not about winning or losing, it's about the cost of being bound to something you can't refuse, watching it consume new people while you're forced to watch from the outside. Yuzuki becomes the new vessel, but she's conscious the whole time. She feels Ai's hunger, her rage, her exhaustion with human cruelty. The show doesn't let you pretend the Jigoku Tsushin is justice anymore. It's a machine that grinds forward whether anyone wants it to or not, and the people trapped inside it are just trying to survive the ride.

Three of Ai Enma's former helpers, Ichimoku Ren, Wanyuudou and Hone-Onna, have settled into quiet, ordinary lives after the Hell Girl vanished at the end of the previous season. That calm breaks when Kikuri shows up to bring them back. Ai returns from the dead in an unexpected way, taking over the body of a schoolgirl named Yuzuki Mikage to keep the Hell Correspondence running. Yuzuki knows Ai is inside her, since she can see whatever Ai sees. When a friend of hers enters their teacher's name on the Hell Correspondence site, Ai uses Yuzuki's body to carry the teacher's soul to hell. Shaken by all this, Yuzuki wonders why she was picked to carry on Ai's work, while the Hell Girl and her assistants take up their grim job once more. The result is a supernatural horror mystery of grudges, revenge and a powered-up Ai.
