Black★Gold Saw

Black★Gold Saw (ブラック★ゴールドソ) is part of the supporting cast of the OVA series Black★Rock Shooter. Her relevance to the plot is still unclear, and her origins, along with her human counterpart, have not been disclosed.

Appearance
Black★Gold Saw is a girl with red eyes and long black hair. A red flame shoots out from her right eye. She has a pair of curved black horns whose color turns to red as it reaches the tip. Like Dead Master, Black★Gold Saw also has skeletal claws. Her outfit is similar to Black★Rock Shooter except for the design of her jacket and her bikini top; her jacket extends into a worn-out cape which is dyed red at the end.

Like all of the "other selves", her eyes have a circular pattern in them.

Her weapon of choice is a large black sword with a long handle and a curved hilt shaped like a pointing-down crescent.

Background
In the beginning of the OVA, she fights Black★Rock Shooter and is victorious, presumably giving Black★Rock Shooter her scars.

It is unknown if she is an "other self" at all, and if she is, whom she is one for and how she relates to Black★Rock Shooter or Kuroi Mato.

Her possible human counterpart in the real world was sitting on the chair of the train at the beginning, but this is unclear as the hairstyle is very common and the eye color is difficult to tell.
