Next City Vault

Next City Maximum Security Vault (ネクスト・シティ), commonly known as the Next City Vault or simply the Vault, is a maximum security detention facility located at the border of Next City and Ultimate City.

It is a "vault" for superhuman villains or other criminals too dangerous to be kept around in regular prisons, such as Mickey Murphy. Visiting hours for the prison are between 1:30 pm and 3:45 pm on weekdays.
