Eleven minutes to establish why these kids are about to die together. Missing Footage doesn't pad its runtime, it uses every second to show you the relationships the games only implied, then locks you in a room with them before everything goes wrong. By the time the OVA ends, you understand what you're losing.
Inside Heavenly Host Elementary School, a group of students discovers disturbing footage recorded within the cursed building's walls. What begins as curiosity about the mysterious recordings spirals into something far more sinister as they piece together fragmented images of supernatural events that predate their arrival. Each frame reveals new horrors lurking in the shadows, and the deeper they dig, the more they realize the school itself may be watching them. This OVA strips away exposition in favor of pure atmospheric dread. Without relying on lengthy explanations, it builds tension through visual storytelling and the mounting sense that some knowledge comes at a cost. The found-footage approach creates an intimate kind of terror, one that feels immediate and inescapable. Horror enthusiasts who appreciate psychological scares over jump-scares will find something unsettling here. Fans already familiar with Corpse Party's lore recognize references that deepen the mythology, while newcomers can experience the raw unease of discovering a dark secret piece by piece. The episode thrives on restraint and implication rather than explanation.
