black star (black rock shooters innocet Soul

Although considered an entity whose purpose is to capture and deliver souls, Rock has shown to have a kind personality toward the inhabitants of the Threshold. However, she suffers from a traumatic event that can cause her to lose control when certain triggers are encountered (e.g., fire and the word "vanish"). What causes her to enter this state is still unknown, as the details of her past have not been clarified. Rock empathizes with the trapped souls, sometimes making her feel guilty for killing them.

Like her other incarnations, Rock takes the appearance of a pale-skinned teenage girl with long, black hair tied in uneven ponytails, with the right hair shorter than the left. A blue flame appears from her blue left eye. Her clothing consists of a black poncho with a white star near the left shoulder, which covers a white shirt with two horizontal black stripes across the chest. She also wears a white skirt and a buckled black belt. She also wears high-heeled black boots.

In the penultimate chapter of the manga, after obtaining Dead's purified soul and deciding to fight Ram, his clothes become those of his original concept, although without the scars.

Her weapons of choice are her ★Rock Cannon and her Black Blade, which are summoned through her partner Ron's shapeshifting powers. She is later able to summon Dead's three-pronged sword and multiple ★Rock Cannons by wrapping themselves around themselves.
