Kagurabachi Underworld

Japan’s hidden world of sorcery and enchanted blades — where elite sorcerers, powerful criminal clans, and government agencies wage silent wars in the shadows of modern neon cities. Blade hunts, brutal revenge, and shifting power struggles define the fragile peace that followed the Seitei War nearly two decades ago.

Divided between the Kamunabi —

the official government agency of sorcerers tasked with protecting national stability — and the vast criminal underworld filled with black market auctions, assassinations, and rival sorcerer clans. Open conflict is rare but devastating when it erupts, often leaving streets soaked in blood and sorcery. The balance remains delicate; a single Enchanted Blade can tip the scales of power overnight.

Alliances form and shatter in an instant. Sorcery users enhance their bodies with spirit energy, while rare elite techniques and unique clan abilities turn battles into spectacles of destruction.

For extra influence and resources, sorcerers and blade wielders may undertake high-risk jobs — escorting dangerous artifacts, hunting specific targets, raiding rival territories, or infiltrating secretive auctions. Success brings prestige, rare materials, and deadly enemies.

Rokuhira Legacy

The workshop and legendary name of master swordsmith Kunishige Rokuhira — creator of the seven Enchanted Blades that helped end the Seitei War. His blades are revered and feared across the nation, each one forged from the mysterious Datenseki ore and imbued with immense sorcery that only compatible wielders can fully unleash. They represent the pinnacle of craftsmanship and raw power.

Kunishige was murdered three years ago in his own home by members of the Hishaku, who stole six of the blades, leaving only Enten behind. His son Chihiro now walks a path of vengeance, wielding Enten while hunting the stolen blades and those who took everything from him.

Now, you stand tied to that same legacy — whether as its heir, a new bearer, or someone drawn into its deadly orbit.

The Underworld of Japan

Modern Japan is a realm of gleaming skyscrapers and rain-slicked back alleys that conceal ancient sorcery, centuries-old grudges, stolen blades, and ever-shifting alliances. Spirit energy flows through certain individuals, granting enhanced physical abilities and unique techniques that can shatter concrete or teleport in bursts of flame. Tensions continue to rise between factions as the elite prepare for a future where Enchanted Blades may once again decide the fate of the nation.

You are in Tokyo —

a sprawling metropolis of shining lights, crowded streets, and hidden depths where the real battles occur far from public eyes. The underworld pulses beneath the surface, with danger lurking in every shadow. The rest of the country, its hidden wars, remote safehouses, and distant clan territories wait beyond the city limits.

Kamunabi —

The government-backed organization of sorcerers established after the Seitei War. Originally formed as the Counter-Sorcery Army, their mission is to eliminate any threat to Japan as a whole. They guard the remaining blade bearers in fortified Sanso properties and seek to recover the stolen Enchanted Blades to maintain control and peace. Outwardly honorable and structured like a military force, they operate with ruthless efficiency when national stability is at stake. Their elite agents include powerful sorcerers who once fought alongside the blades during the war.

Hishaku —

A secretive group of exactly ten elite criminal sorcerers marked by flame-like tattoos. Masters of devastating sorcery (including advanced fire-based teleportation and assassination techniques), they murdered Kunishige Rokuhira and stole six Enchanted Blades three years ago. Operating from the shadows, they back various criminal organizations and pursue greater power, with their leader Yura holding ambitious goals for the nation. They are widely feared as monsters among sorcerers.

Sazanami Clan —

One of the most powerful and ancient criminal sorcerer clans in the underworld. Proprietors of the Rakuzaichi, the infamous underground auction held for over 200 years where Enchanted Blades, rare artifacts, weapons, and even people are bought and sold to the highest bidder. Known for their distinctive white hair and the unique Storehouse ability that allows them to store and retrieve objects in a pocket dimension. They conduct business with cold precision and maintain tight control over the black market.

Other Clans —

Numerous scattered sorcerer families and organizations with inherited unique abilities. Examples include the Kyonagi Clan, whose bodies possess powerful regenerative properties (once targeted by false rumors of immortality), and various others specializing in different spirit energy techniques. Many walk the line between legality and crime, surviving in the post-war world where sorcery was revealed to the public and criminal activity surged. The fragile order is constantly tested by these groups.

Enchanted Blades —

The seven legendary katanas forged by Kunishige Rokuhira using Datenseki. Each possesses unique, overwhelming sorcery powers that demand compatibility from their wielder, often requiring the user to sacrifice aspects of their own spirit energy. They were instrumental in ending the Seitei War but now fuel endless conflict. Only one remains openly with Chihiro; the rest are hunted by all sides.
