Occultic;Nine

Lore & Background

The murder brings together nine individuals in the Kichijoji district, each connected through different circumstances. These include Ryoka Narusawa, who perceives supernatural phenomena; Miyuu Aikawa, a clairvoyant fortune-teller; Toko Sumikaze, an occult magazine editor; Ririka Nishizono, a doujin manga author whose works predict real events; Aria Kurenaino, a curse-caster unknowingly involved in the murder; Kiryu Kusakabe, an astral projection practitioner; and Shun Moritsuka, a detective investigating occult occurrences. The group later discovers that 256 people drowned in Inokashira Park's lake on February 25 in what becomes known as the '256 Incident.' Through decoding Hashigami's research, they find a list of 256 names matching the drowning victims, and realize their own names appear on that list. They determine they are dead, existing as astral bodies sustained by electromagnetic transmissions from an antenna array called 'Odd Eye,' operated by the Society of the Eight Gods of Fortune, a front for the Musashino Medical Group (MMG). The MMG has been conducting experiments using scandium injections to capture and preserve human consciousness after death, with the 256 victims serving as first-generation test subjects. The group learns that the astral plane experiences temporal dissonance—one day of ghost experience equals about one minute of real time—meaning their physical bodies remain in the lake within the window for possible resuscitation.

Reader's Guide

Occultic;Nine is significant as a multi-media entry in the Science Adventure franchise, blending occult themes with speculative science. The series explores concepts of electromagnetic consciousness, astral projection, and the potential for technological immortality, drawing on suppressed research attributed to Nikola Tesla. Its narrative structure, involving nine interconnected characters whose deaths are revealed to have occurred early in the story, creates a mystery that recontextualizes the entire plot. The work's treatment of pseudoscience and conspiracy, including the use of scandium to capture souls and the 'New World System' for commercial immortality, reflects contemporary anxieties about technology, consciousness, and corporate control. The series also incorporates the legacy of Yuta's father, Koresuke Gamon, whose modified Skysensor radio becomes a key tool, and introduces Aveline Tesla, Nikola Tesla's illegitimate daughter, as the guiding voice 'Zonko.' The temporal dissonance mechanic—where the characters' post-death investigation spans weeks subjectively but only minutes in real time—adds urgency to their quest to return to their bodies.
