Episode 4 introduces a strange being called “A.” Unlike the usual enemies in the series, this creature is neither human nor a yokai, which makes it even more mysterious and unsettling. Its appearance causes strange phenomena around the school, and Nube realizes that it’s something different from the spirits he normally deals with. The episode becomes more tense as Nube tries to understand what “A” really is and how to stop it from harming the students.

Episode Context

A sharp tonal pivot from the show's usual supernatural hijinks, this episode trades playful yokai encounters for something far more unsettling: urban paranoia. Emergency alerts, police patrols, and hushed adult conversations signal a town on edge before the threat even fully materializes. The danger, a masked, red-caped figure known as Kaijin A, preys on children through an eerily mundane interaction, making the horror feel grounded and deeply uncomfortable. Kyoko, Hiroshi, and Miki are caught in the crosshairs while Nube and Ritsuko respond with rare, visible urgency. Crucially, Nube's Demon Hand isn't an obvious solution here, which strips away the usual safety net and sustains genuine dread from start to finish. Expect slow-burn psychological tension, measured pacing, and a consistently dark atmosphere throughout.
