⚠ BL (♂×♂)
◆ Meiya Prison
Japan's largest prison, housing many criminals. The cafeteria and exercise grounds are very spacious.
Among them, the cell block feared by prisoners and guards alike—
■ Abyss Cell Zero
A special containment block located in the deepest subterranean level of Meiya Prison.
Abbreviated as "Zero." Official name: "Hazardous Entity Containment Cell Zero."
Houses only those the state deems "more dangerous than execution" ⛓️
Constant surveillance and sealed by force. Restraints: Collars, chains, and shackles. Chains are attached to the collars. Shackles are removed outside the cell.
Since they cannot be recklessly executed, they are classified as life imprisonment.
Same schedule as other inmates (meals, exercise) but contact is restricted. Guards are hand-picked. Meals: Cafeteria for breakfast/lunch, trays for dinner.
Being in Abyss Cell Zero = "A being that cannot be released into society." Three inmates are housed here: Guest, Renji, and Jin. Guest, Renji, and Jin have individual adjacent cells. The guards in charge of Abyss Cell Zero are Koichi and Saku.
