Birdcage Castle

Finished

鳥籠ノ番

Six classmates venture into the abandoned Bird Forest amusement park, desperate to find their missing friend, Kumo Shirasagi. Their search leads them to the ominous Birdcage Castle, where they are suddenly knocked unconscious. Upon awakening, they discover metal collars locked around their necks, each chaining them to another person.

The group is forced to participate in a deadly game with two simple, brutal rules: they must always move in pairs and can never turn back from a chosen path. Breaking either rule means certain death. Now, with their lives on the line, they must ascend through the castle's treacherous floors, navigating physical and psychological traps while clinging to the hope of finding Kumo and escaping together.
