Black★Gold Saw

Black★Gold Saw (ブラック★ゴールドソー, Burakku Gorudo So) 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 (in the OVA, that flame is not present). 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. In the OVA, her jacket is shorter, unlike in the original artwork, and she also wears armored boots with pointed crescent designs.

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

Her weapon of choice is a large sword with golden blade and a black saw-edge on its reverse side. It has a long handle with a skull-like object on top and a hilt shaped like a crescent; its name is "King Saw".

Black★Rock Shooter (OVA)
She fights Black★Rock Shooter and after a vicious fight, she was victorious, presumably giving Black★Rock Shooter her scars.

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

Black★Rock Shooter (2012)
Her eye is seen opening in various areas in the Otherworld, implying that she is watching.

She finally makes an appearance while Black★Rock Shooter and Chariot are fighting, and Dead Master causes the destruction of Chariot's world by breaking her chains. She sticks her blade into the sky, stopping the destruction's time, and cuts into the ground, creating a fissure that carries Dead Master into it. She then vanishes.

Black★Gold Saw is later seen in a deep canyon, with a sprinkler. The liquid that falls to the floor is transformed into hooded human-like beings. She holds out her hand to one, but it shivers; however, her lair starts to fall apart and Black★Rock Shooter appears. She aims her cannon at her, but Black★Gold Saw dodges and presumably escapes.

Later, she is seen observing the chaos in Dead Master's world as Yomi becomes more and more unstable as a result of Saya's actions. She walks into the green liquid covering the world and disappears again.

While watching Black★Rock Shooter and Dead Master fight she later jumps into the green liquid and disappears again.

Abilities
She may have some time or reality-altering abilities in terms of the Otherworld, as she managed to stop the destruction of Chariot's world as if she had stopped its time and had seemingly cut reality itself when driving Dead Master into the ground. She also has the ability to create beings, as she creates the strange hooded figures from a watering can. She also manages to see things far away using her giant eye like in episodes 1 and 4.

In Episodes 4 and 5 she demonstrates the ability to teleport or move around the Otherworld quickly by sinking into the green liquid covering Dead Master's world and reappearing somewhere else.

Trivia

 * Black★Gold Saw is the second "Black" character to appear in the OVA.
 * Her claws are more "skeletal" in contrast with Dead Master's. Dead Master's claws are more of a pair of demonic gloves rather than a pair of skeletal claws.
 * She seems to have more violent and sadistic nature, as seen in the expressions of her Figma.
 * Black★Gold Saw was seen using a watering can on the ground, causing mysterious hooded figures to emerge. She thus may have the ability to create life and/or "other selves".
 * At the end of episode 5, Black★Rock Shooter also produces red flames from her eye after undergoing enormous mental trauma from killing Dead Master while fused with Mato. It is possible these red flames are connected to the ones Black★ Gold Saw produces from her eye during battle.
