"Seeking the truth hidden beyond the boundaries of the world."

秘封倶楽部 (Hifuu Kurabu, “Secret Seal Club”) is an independent occult research circle said to have existed in the Outside World across multiple eras. Though small in size, the Club focuses on urban legends, paranormal phenomena, and the structural boundaries separating worlds.

Its approach is observational rather than ritualistic. The Club does not conduct exorcisms or séances. Instead, it studies locations where reality appears unstable.

Origins – University Era

The earliest confirmed incarnation was founded by university students Renko Usami and Maribel Hearn.

Officially registered as a “medium research society,” its true purpose was the study of boundary irregularities — places where the separation between worlds thins.

Core hypothesis:

The world is defined by its borders. Where a border weakens, another side may be observed.

Documented Field Sites

Records describe investigations and visits to:

• Kyoto and Tokyo, Japan — accessed via high-speed rail for urban legend verification and historical boundary analysis.
• Lunar studies — speculative research on moon travel and the conceptual boundary between Earth and the Moon.
• The Torifune ruins / orbital habitat site — a derelict research facility linked to anomalous findings.
• Remote paranormal locations — abandoned fields, liminal transit zones, and areas known for recurring unexplained phenomena.
• Subterranean and hidden sites in Japan — locations marked by spatial distortion, folklore density, or restricted access.
• Old Adam Bar — a quiet meeting place where discussions, records, and reflections were compiled.

These sites form the foundation of the Club’s documented archive.

2015 Incarnation – High School Circle

In 2015, a high school circle operating under the same name emerged in Japan under Sumireko Usami.

This group investigated contemporary urban legends and psychic phenomena. Despite differences in age and structure, its research themes closely paralleled the earlier university-era Club.

The connection between these incarnations remains unresolved.

Current Chapter

This Steam group serves as an Outside World chapter inspired by the documented activities of the Hifuu Club.

Areas of interest include:

• Urban legend analysis
• Boundary theory and parallel world speculation
• Archival of anomalous reports
• Discussion of documented field sites

Membership is open to observers, researchers, and those who suspect the world’s borders are not absolute.

Notice

This is a fan-created parody group for entertainment and community purposes.

All field investigations here are theoretical.
Any confirmed boundary breaches should be logged carefully.
