Nobody talks about this one. A priest and a nun walk into an impossible miracle, and the show treats the investigation like a locked-room mystery instead of a sermon. By the end, faith itself becomes the unreliable narrator, and you're left holding a case that refuses to close.
Father Hiraga and Professor Saji return to investigate another impossible case that shakes the foundations of faith. When a mysterious soup prepared by a woman begins producing inexplicable healing effects, the two men find themselves caught between scientific rationality and spiritual mystery. The case spirals deeper as they uncover connections to dark rituals and supernatural forces lurking beneath the surface of an ordinary town. What appears to be a miracle hides something far more sinister. As Hiraga's faith wavers and Saji's skepticism reaches its limits, they must confront the blurred line between divine intervention and something altogether different. The investigation pushes both men to question what they truly believe and whether some mysteries exist beyond the reach of reason or prayer. This OVA strips away complications and focuses on a tightly wound story of two investigators facing forces that defy easy explanation. It captures the series' signature tension between the rational and the inexplicable, delivered in a single, concentrated chapter that rewards viewers familiar with the pair's history while standing on its own as a self-contained mystery.
