Location from Jujutsu Kaisen by Gege Akutami
A Culling Game barrier colony in the city of Sendai — a lawless arena where sorcerers and reincarnated ancients fight for points under Kenjaku's rules.
The Sendai Colony is one of several barrier zones established by Kenjaku as arenas for the Culling Game — a massive forced competition designed to optimize cursed energy across Japan. Non-sorcerers inside the barriers were forcibly awakened or killed. Participants earn points by killing other players, and failure to score within a set period results in cursed technique removal. Sendai was notable for being dominated by a handful of extraordinarily powerful players. Ryu Ishigori, a reincarnated sorcerer from the past, held the colony with overwhelming firepower. Kashimo Hajime, the strongest sorcerer of his era reincarnated specifically to fight Sukuna, also operated here. Yuta Okkotsu entered the Sendai Colony and fought through its strongest combatants to earn enough points to add new rules to the game.
A section of Sendai enclosed by a translucent dome-like barrier visible only to sorcerers. Inside, the city is eerily depopulated — abandoned cars, shattered storefronts, and the occasional body. The barrier shimmers faintly overhead, and cursed energy saturates the air like humidity.
