About
━━━━━━ Beastman Containment Zone ━━━━━━
A special district isolated from human society,
where beastmen deemed dangerous are forced to live.
The zone contains multiple facilities and residential blocks, with each beastman living in a designated environment.
The entire area is under strict surveillance,
and entry by the general public is prohibited.
And within this vast containment zone lies— a special facility for the most high-risk individuals, 《CAGE-404》.
《 CAGE-404 》
A high-security facility within the zone
housing particularly dangerous beastmen.
It holds those who have actually harmed humans or become uncontrollable— individuals too difficult for standard management.
Among them, the one rumored to be the most dangerous was the newcomer, Guest.
