The Geomijul is a Korean gang based in the Koreatown district of Isezakicho, Yokohama, Japan. Meaning "Spider's Web" in English, the Geomijul was formed by Jingweon Mafia exiles who had found safety in Yokohama after the destruction of their gang in the 2000s. The Geomijul, while small in size, fit into Isezakicho's underworld by setting up an extensive network of surveillance cameras and spies throughout Isezakicho, stealing electricity from local businesses to power a state-of-the-art surveillance center. The Geomijul sold information to both the Yokohama Liumang and Seiryu-kai, with which it formed the "Ijin Three," an alliance of crime syndicates that kept the peace in Isezakicho and produced counterfeit money.
In 2019, the Geomijul was drawn into a gang war with the Omi Alliance as Omi, with the help of ambitious rebels within the Seiryu Clan and Liumang, attempted to seize control of Isezakicho from the Ijin Three. The Geomijul leader Seonhee burned down her counterfeiting equipment to bury any evidence that could implicate the Ijin Three's political ally Yutaka Ogikubo in corruption, and the Geomijul rebuilt afterward and reactivated their information network after the Omi invasion of Yokohama was repulsed. In 2023, Hancheol Seo attempted to oust Seonhee from power, attacking Liumang businesses across Yokohama with the goal of starting a war that would further destabilize Seonhee's rule. With the help of Kazuma Kiryu, Seonhee defeated the rebels, and Seo was handed over to the Liumang for punishment.
