- Villainy Prison (地底特別獄舎 Birenii Purizun)
- Villainy Prison was a dilapidated underground prison said to hold the most notorious criminals. The monster Devil Rebirth was sealed away here for murdering 700 people, until he was freed by Jackal, a former inmate, but shortly afterwards both of them were terminated by Kenshirō. There is also a bar nearby that serves as one of Jackal's hideouts.
In the anime it serves as a Bloody Cross-controlled stronghold.
