A cozy detective agency run by an all-male pop group hits an unexpected snag when their sole female colleague vanishes without a trace. Her disappearance pulls at threads connecting to one member's shadowy past, forcing the band to confront secrets they'd buried years ago. What started as a simple case spirals into something far more personal and dangerous, with each clue revealing how deeply entangled their lives have become. The mystery unfolds with the warmth of slice-of-life moments between investigations, balancing light banter and genuine camaraderie against the creeping dread of not knowing where their friend is. Romance simmers in the background as emotions run high, and the stakes feel real despite the unconventional setup of detectives who perform on stage. This OVA works best if you appreciate stories where found family dynamics ground darker mysteries, where humor and sincerity coexist, and where pop stars solving crimes somehow feels exactly right. The pacing moves briskly through its single episode, squeezing genuine tension and heart into a compact story that respects your time while delivering satisfying closure.
