Requiem appears in the film *Over The Sky* (also known as *Kimi wa Kanata*). This entity stands as the guardian of the World Border, a purgatory-like realm serving as a transition point for souls before they choose their afterlife. Requiem enforces the rules governing this realm with unwavering strictness. When the protagonist Mio arrives prematurely due to an out-of-body experience, Requiem forbids her return to the human world. Its primary function is to ensure souls proceed forward to their designated afterlives, not reverse their journey. Requiem's role is confined to acting as an antagonistic force opposing Mio's efforts to reclaim her memories and return home.
