★Rock Cannon

The ★Rock Cannon (★ロックキャノン, Rokku Kyanon) is the signature weapon wielded by Black★Rock Shooter. It is the primary weapon wielded by the character and many of her incarnations. Like the character herself, the weapon is different in every media it appears in, including its name and capabilities.

Appearance
The ★Rock Cannon in its original appearance is a large gun with a lengthy barrel. The cylinder connects the barrel with the base of the gun, where the handle and trigger are located, the latter further in. A frame resembling a field carriage is attached to the base.

Black★Rock Shooter OVA
The ★Rock Cannon appears in Black★Rock Shooter's possession following her fusion with Mato Kuroi. She carries it with her as she crosses the Otherworld to the place where Dead Master resides, and uses it to battle against her. Black★Rock Shooter later turns the barrel of the ★Rock Cannon into a blade, using this form to destroy Dead Master's skulls and cut through the chains intended to block her from reaching Dead Master. The ★Rock Cannon is not seen again after Dead Master captures Black★Rock Shooter in chains.

In the OVA, the ★Rock Cannon's appearance is closely taken from that of its original appearance. The weapon is shown to be able to fire multiple rocks at once, and transform its barrel into a blade, turning it into a lance-like weapon more suitable for fighting up close.

Black★Rock Shooter THE GAME
Stella obtains the ★Rock Cannon after being awakened in her stasis tube, along with the Black Blade. The weapons might be an invention of Prof. Gibson. The weapon has a bayonet attached to it so that it may double as an effective close-range weapon when Black Blade is unavailable.

Black★Rock Shooter (TV Anime)
The ★Rock Cannon first appears in How Much More Do I Have to Scream?, where Black★Rock Shooter summons the ★Rock Cannon to fire at the eye of Black Gold Saw that was watching her from far below in an abyss. Black★Rock Shooter summons it again later to fight back against Chariot, and has the opportunity twice to fire directly at her, but Dead Master prevents her from doing so both times. In Dawn Envelopes the Sky, Black★Rock Shooter transforms the ★Rock Cannon into a gatling gun to break through the wave of macarons unleashed by Chariot's spider-like tank, Mary.

In the episode Black★Rock Shooter, the ★Rock Cannon is transformed into two gatling guns side-by-side, cannonading against Dead Master's army of the dead. It is shown to have instantly turned back into its default form after a larger minion of the dead raises its hammer to find Black★Rock Shooter completely unharmed. Black★Rock Shooter uses the cannon in conjunction with her Black Blade to fight against the army until she fights Dead Master herself.

After Black★Rock Shooter turns insane from being affected by Mato Kuroi's mental trauma, the ★Rock Cannon in her possession becomes the Insane Cannon Lance. In Let's Go Beyond This World, another ★Rock Cannon appears in Black★Rock Shooter's realm of the Otherworld. Black★Rock Shooter tells Mato to use it to fight back, which Mato refuses, but grabs it to block Black★Rock Shooter's punches. The force of the impact causes Mato to inadvertently puncture Black★Rock Shooter with the cannon, who takes it and breaks it on her knee, and continues beating Mato.

Mato summons the ★Rock Cannon in its singular gatling gun form and fires at Black★Rock Shooter, who fires back using the Insane Cannon Lance. As bullets and sparks fly, the firepower of the Insane Cannon Lance manages to destroy Mato's ★Rock Cannon, but using the colors that broke through the sky of Black★Rock Shooter's realm, representative of the other Other selves, Mato summons a gigantic ★Rock Cannon that fires a rainbow-colored blast that annihilates Insane Black★Rock Shooter once and for all.

In the TV Anime, the ★Rock Cannon is of a shorter overall length. Its cylinder glows blue, and it has three separate prongs along the side of the barrel. In its default form, the ★Rock Cannon seems to only be capable of firing one rock at once, albeit at a quick pace. It can also charge its shots. In its gatling gun forms, the ★Rock Cannon has a much faster rate of fire, visibly spending countless shells as it fires.

Black★★Rock Shooter DAWN FALL
In Black★★Rock Shooter DAWN FALL, the ★Rock Cannon is named the Coilgun (コイルガン, Koiru Gan).
