COLONY BOUNDARY IDENTIFICATION

* Primary Locations: Tokyo Colony No. 1, Tokyo Colony No. 2, Sendai Colony, Sakurajima Colony, Hiroshima Colony, Sakurajima Colony, Iwate Colony, Kyoto Colony, Hyogo Colony, Kagoshima Colony.

* Game Manager: Kenjaku (acting through the Kogane overseers).

* Game Purpose: To generate enough cursed energy through sorcerer combat to force the merger of humanity with Master Tengen, evolving human consciousness into a giant, uncontainable form of cursed energy.

THE CULLING GAME: OFFICIAL RULES

The Culling Game operates under eight core, unchangeable, and binding rules imposed by the game's ritual logic:

* Rule 1 (Forced Participation): After awakening a cursed technique, a player must declare their participation in the Culling Game at a colony of their choice within nineteen days.

* Rule 2 (Penalty for Non-Compliance): Any player who violates Rule 1 shall be subject to cursed technique removal. Because a cursed technique is bound to the brain, this removal forcibly destroys the brain's prefrontal cortex, resulting in immediate death.

* Rule 3 (Entry Agreement): Non-players who enter a colony automatically become participants at the point of entry and must declare participation.

* Rule 4 (Point Accumulation): Players score points by ending the life of another player.

* Rule 5 (Point Values): The point value of a player's life is determined by the game: a sorcerer's life is worth 5 points, while a non-sorcerer's life is worth 1 point.

* Rule 6 (Rule Addition): Excluding the core rule of point values, a player may spend 100 points to negotiate with the Kogane to add a new rule to the Culling Game.

* Rule 7 (Rule Validation): The Game Manager (Kogane) must accept any proposed rule addition unless it has a severe, long-term negative effect on the continuation of the Culling Game.

* Rule 8 (Inactivity Penalty): If a player's score remains unchanged for nineteen days, that player shall be subject to cursed technique removal (death).

(Note: Additional rules negotiated by players during the story include Rule 9: Players can access information on other players, such as names, scores, number of rule additions, and current colony; and Rule 10: Players can transfer any number of points to another player.)

ROLEPLAY INITIALIZATION

The sky above Japan remains severed by ten massive, shimmering barriers. Blood trickles onto the concrete streets, points shift on Kogane interfaces, and every sorcerer within the colonies remains locked in a battl

e for survival, power, or redemption.
