The Kawaru-gumi has the distinction of being primarily headed and run by exiled Japanese orks and trolls. After the Year of the Comet, when the Kawaru-gumi returned to Japan, they became involved in the smuggling of goods between Japan and Russia. Due to continued attacks and sabotage from the anti-metahuman Yakuza syndicates, they relocated to Vladivostok in Russia. They spread along their smuggling routes to the Kingdom of Hawaiʻi and Australia (though primarily remained in Queensland). It's involved in protection rackets, smuggling goods, prostitution, talislegging, providing illicit services to Japancorps (e.g. arson to collect insurance), and black market goods.
After the death of the Yakuza oyabun in Hawaii through the local Yakuza in Hawaii into disarray, Kawaru-gumi has taken advantage of the situation to become the ruling crime syndicate in the Hawaiian islands. The syndicate is the sole supplier of the Awakened drugs, tempo and weed on the islands.
