Phantom: Requiem for the Phantom is the second anime adaptation of Nitroplus' suspense visual novel game Phantom of Inferno (originally from 2000), after an earlier Phantom OVA. This time, however, the format of choice is a TV anime series created by studio Bee Train, with Koichi Mashimo directing the thing - as he has done with several more girls-with-guns anime (Noir, Madlax, El Cazador), among others (.Hack franchise, Blade of the Immortal).
