Reports of enigmatic entities dubbed "Hologram Ghosts" have been a trending subject on social media for the last few years. Rumors suggest that multiple individuals have become victims of these apparitions. Survivors of encounters with these paranormal beings describe them as resembling malfunctioning holograms. Hiro Amanokawa, a middle school student at Hazakura Academy, considers these sightings to be nothing more than an urban legend. Yet, as the frequency of incidents rises, he is reminded of the day his father abruptly disappeared, leaving behind only peculiar digital watches as traces of his vanishing. Similar to the other cases, the fate of Hiro's father defies conventional logic. When a classmate at the academy is attacked by a Hologram Ghost, Hiro and his friend Kiyoshirou Higashimitarai resolve to investigate the situation. Hiro is unaware that this inquiry will mark their initial step into uncovering a perilous world previously unknown to humanity.
