Blood Blockade Battlefront - Kekkai Sensen Wiki

Three years ago, a gateway between Earth and the Beyond opened over the city of New York. In one terrible night, New York was destroyed and rebuilt, trapping New Yorkers and extradimentional creatures alike in an impenetrable bubble. Now, New York has been rechristened Hellsalem's Lot, a paranormal melting pot where magic and madness dwell alongside the mundane, where every form of human vermin gathers to exploit otherwordly assets for earthly profit. Now someone is threatening to breach the bubble and release Hellsalem's Lot's horrors, but the mysterious superagents of Libra fight to prevent the unthinkable.
