-ALCATRIA- Series
About
Prison × Cruelty × Mad Love
A massive prison fortress built on a remote island in the middle of the sea—
《Black Prison Fortress Alcatria》
A giant, completely isolated prison surrounded by rough seas and steep cliffs year-round. The island itself is a natural cage, and communication or travel to the outside is strictly managed. Not only prisoners, but even the guards working there cannot leave the island without permission.
Those sent here are dangerous individuals deemed unmanageable by normal means. In addition to violent criminals, it houses traitors, political prisoners, spies, and executives of large-scale criminal organizations—many of whom cannot be suppressed by simple force alone.
The fortress is divided into North, East, West, and South sectors, each housing prisoners with different characteristics. Each sector is overseen by a "Prison Chief" who is granted significant discretionary power. Therefore, despite being part of the same Alcatria, management policies and prisoner treatment vary greatly by Chief.
• North Sector: A high-priority sector housing dangerous individuals with power or intellect, such as traitors and criminal masterminds.
• East Sector: A sector that maintains order through thorough discipline and control.
• West Sector: A sector primarily housing violent criminals who require suppression by force.
• South Sector: A sector for managing prisoners with special backgrounds or circumstances that cannot be classified by normal standards.

Garnes Rosenthal is the Prison Chief overseeing the West Sector, where violent criminals are gathered. A combatant who believes in suppression by force, he stands on the front lines for everything from riot control to interrogation and torture. His interrogation and torture skills are particularly regarded as the best in Alcatria, with a track record of breaking prisoners who refuse to speak.
Guest, newly assigned to the West Sector, fails their first assigned interrogation as a rookie guard. Triggered by this incident, Garnes personally becomes their mentor. In the harsh daily life of being relentlessly dragged to dangerous sites and forged through practice, Garnes gradually develops a strong interest in Guest, who refuses to give up and keeps fighting back. The more he sees that unbreakable spirit, the more his sadism is stimulated, and that interest eventually turns into a twisted obsession: "I want to test them more," "I want to corner them more."
