WAKURABA NO KUNIThe Land of WAKURABA
Detailed Record

A land of 'anomalies' that drifts between the mortal world and the spirit realm.
A history of autonomy stretching back to the ancient Onmyo Bureau, and coexistence with yokai that lives on in the modern day.
This is a sanctuary for those who stood up before anyone else.

I. Basic Structure of the World and the "Principle of Three Layers"

The Mortal Realm (Utsushiyo)

The modern society enjoyed by humans. The existence of yokai is kept secret, and public institutions like the Ministry of Defense secretly cooperate with Wakuraba to request yokai extermination for national defense.

The Spirit Realm (Kakuriyo)

A different world where yokai and the souls of the dead churn. A dangerous realm where yokai that feed on the vital energy of living beings roam, constantly aiming to invade the mortal world.

WAKURABA

Anomaly (Iso)

A borderland region. Those without power who wander in become 'spiritually lost,' entering an unstable world where their brains reject recognition and they see distorted visions.

❖ Records of Autonomy and Geography

II. Founding and OriginFounding Ancestors: Originates from a "mass spirit loss incident" during the Heian period where a faction of the Onmyo Bureau, resisting the corruption of the imperial court, collectively transferred to the Anomaly.Origin of the Name: Named after "Wakuraba" (diseased leaves), referring to "pioneers who stood up before anyone else, even while being eroded by the vermin of bureaucracy."Modern Form: While based on a self-sufficient lifestyle, there is also a free-spirited atmosphere of commuting to companies and schools in the mortal world.

III. The Boundary and GeographyScale of the Barrier: A massive barrier approximately 50km in radius, maintained by the spiritual power of the Head of Onmyo. Only the inside is a sanctuary.Center: The residence of the Head of Onmyo in a hilly area. Residential areas and government offices surround it.North: A mountainous region with strong spiritual energy. A sacred area inhabited by powerful yokai and their familiars.

Social Systems and Culture

❖

Pass System

Wakuraba and the mortal world are connected by barrier devices called "Transfer Gates," but free passage is not permitted. A "Pass" is required for entry and exit, issued and approved by the Administrative Bureau. The issuance of a pass requires a legitimate reason (mission, trade, special permission, etc.) and is subject to strict screening.

❖

Residential Style

The basic architectural style is Japanese, but it is not a complete traditional style, incorporating unique building materials and structures of the Anomaly. Many residences have special spaces for housing Shikigami and integrated simple barrier devices. Ordinary Onmyoji often live in tenement-style apartment buildings, and members of the Samurai Bureau also live in communal housing.

❖

Attire Culture

Japanese clothing culture remains strong in Wakuraba. There are weavers and tailors within the country who produce traditional attire. In particular, special garments called "Onmyo Robes" are worn during festivals and for missions involving frequent combat. Many Onmyoji wear Western clothing brought from the mortal world for daily wear, but Japanese attire is the basic standard for formal occasions within the country.
