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 as well as her origins are still unclear, as they have not been disclosed. Her human counterpart has been revealed to be Saya Irino.

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's 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.

Following Mato's link with Black ★ Rock Shooter and subsequent mental breakdown, causing BRS to go insane, Black ★ Gold Saw is seen watching BRS's transformation. Upon iBRS' reveal, Black ★ Gold Saw begins her attack, managing to leave a deep gash in Insane Black ★ Rock Shooter's right arm to which the latter rips it off as Black ★ Gold Saw backs away. She then uses King Saw to try and shield herself from the hail of bullets raining down on her due to Insane Black ★ Rock Shooter's Cannon Lance. As the fight continues, Black ★ Gold Saw manages to rush past Cannon Lance, which was being tossed around by iBRS' chains, and try to take advantage of an opening.

Cannon Lance reveals to have a backwards firing gun that shears off Black ★ Gold Saw's right arm, causing her to miss her attack as King Saw falls in front of Black ★ Rock Shooter and sending BGS skidding across the ground. Before Insane Black ★ Rock Shooter could begin her assault again, Black ★ Gold Saw retreats by dissolving into the ground, but is pursued as Insane Black ★ Rock Shooter uses King Saw (which she manipulates with a chain), Cannon Lance, and Insane Blade Claw to rip the portal open and dives in. In the next world, Black Gold Saw takes out her watering can and creates a small army of the hooded beings again which hardly slows Insane Black ★ Rock Shooter.

As Insane Black ★ Rock Shooter closes in, Saya links with Black ★ Gold Saw and tries to speak out to Mato within Black ★ Rock Shooter. The tactic seems to work as iBRS' attack suddenly stops and can't seem to get her arm down. Insane Black ★ Rock Shooter is then thrown back against a pillar by an unseen force and is then pinned and restrained by several more pillars. Black ★ Gold Saw, seeming to be under full control of Saya, then uses the watering can to create something of a mirror beneath her where Saya can relay her memories.

After the flashback, Insane Black ★ Rock Shooter breaks out of the prison and rushes Black ★ Gold Saw with King Saw. With one last plea, Black ★ Gold Saw closes her eyes, seeming to accept her fate but is saved by STRength, who manages to catch iBRS off guard and send her flying into a pillar. Before IBRS could continue her attacks, STRength breaks the ground beneath them, grabs Black ★ Gold Saw, and escapes to her own world. Black ★ Rock Shooter gives chase until they all appear in a rubix cube-style world with the cube structure floating in mid air. STRength sets the unconscious Black ★ Gold Saw down as she is then moved elsewhere for protection.

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 episode 1, she can summon a massive King Saw out of the ground. In episode 6 she can sprinkle a mirror-like surface on the ground that shows Saya's memories

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 appears similar to the younger Saya Irino instead of Saya's younger short-haired appearance.
 * 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".
 * When BGS was redesigned (both in the original artwork and in the anime), the crimson flame that BGS were missing or rather, removed. Since then, there are no more artworks of BGS depicting her with her tradmark flame. Because of that, she became the first "Black" character never to show eye flames.
 * She maybe the first character in the anime who faced BRS's fury and never died. However, she got her sword arm ripped off by iBRS's Insane Cannon Lance's back vulcan. She would have died if STRength had not protected her.
