Black★Rock Shooter is the titular character and main protagonist of many projects, including the anime OVA Black★Rock Shooter, the RPG of the same name, the anime series and the manga Black★Rock Shooter ~Innocent Soul~. She was an original concept created by huke who participated in the release of the song "Black★Rock Shooter" by supercell.

Original Concept:

Black★Rock Shooter's original design is of a pale-skinned, blue-eyed girl, with black hair in uneven twintails; the right lock of her hair is shorter than her left. She bears two scars on her midriff. A blue flame shoots out from her left eye.

Her clothes consist of a string bikini top under a black jacket. The jacket has a white stripe running along the length of each of her sleeves and has a white star design on the front (left side) and back. She also wears a pair of tight-fitting shorts, gloves, and black knee-high boots.

Her weapons consist of a black-hilted katana later named as Black Blade and a large gun called ★rock Cannon. She is the "other self" of Mato in the other world.

OVA:

Black★Rock Shooter is also given a personality in the OVA. She is depicted as a calm and collected girl, not speaking at all until her confrontation with Mato, near the end of the OVA. She also does not focus on anything except the most important thing she has to do at the moment.

She is shown to be very skilled in fighting, despite being quickly taken down by Black★Gold Saw in her first shown battle. Black★Rock Shooter is able to fight evenly with Dead Master, despite appearing to try not to hurt her.

Anime Adaptation:

Black★Rock Shooter has been redesigned for the anime, with some new elements possibly inspired by the designs of White Rock Shooter and Black★Rock Shooter Beast, as her new jacket and boots (which are now more blue than black) have similarities to both WRS' and B★RSB's clothing. Like her hairstyle in the PSP game, her hairstyle is spikier compared to her OVA appearance. She no longer has any scar on her midriff. She wears her trademark hood more often than she does in other media. Black★Rock Shooter in the anime seems to be more brutal than any other B★RS incarnation, having beheaded Chariot and Arata's possible other self, and killed Dead Master.
