Black★Rock Shooter (ブラック★ロックシューター Burakku Rokku Shūtā?) is a Japanese media franchise based on characters created by illustrator Ryohei Fuke also known as Huke. It revolves around its eponymous character, a mysterious black haired girl with a blazing blue eye. The original illustration inspired a song of the same name by Supercell, which gained popularity on the Nico Nico Douga website. A 50-minute original video animation based on the franchise was produced by Yutaka Yamamoto‘s studio Ordet, written by Nagaru Tanigawa and Shinobu Yoshioka, and directed by Shinobu Yoshioka. A “Pilot Edition” was released on DVD and Blu-ray Disc in September 2009, before the full version was released on DVDs bundled with select magazines from July 24, 2010, subtitled in seven languages, followed by a retail release on December 17, 2010. An eight-episode television anime series, produced by Ordet and Sanzigen, aired on Fuji TV‘s Noitamina programming block between February 2 and March 22, 2012. The franchise has also spawned several manga series and a video game for the PlayStation Portable titled Black Rock Shooter: The Game, each set in their own universe.
While each piece of media takes place in its own universe, they each focus around Black Rock Shooter, a mysterious black haired girl who possesses a burning blue eye and a powerful cannon that can shoot rocks at high speed. Other characters also appear in more than one form of media.
The OVA focuses on a girl named Mato Kuroi, who befriends another girl, Yomi Takanashi, upon entering school. As the two start to drift apart, with Yomi becoming jealous of Mato’s friendship with Yuu Kotari, Yomi suddenly disappears. As Mato searches for her, she is taken to a strange world where she meets the mysterious Black Rock Shooter, who merges with her and helps her search for Yomi, fighting off the evil Dead Master who possessed her. The television series uses the same characters from the OVA in a similar but slightly different storyline. As Mato enters middle school and becomes friends with Yomi, she soon faces personal troubles and the influence caused by another world where Black Rock Shooter fights other girls.
The manga series, Black Rock Shooter: Innocent Soul, follows Black Rock Shooter and her serpent partner, Ron, as they venture the Hazama, a world between Heaven and Earth where stagnant souls that have had regrets become trapped. Left alone, these souls can become demons that can pull in other souls, so it is up to Rock to stop them so they may ascend to heaven. Black Rock-chan is a comedy series following the everyday life of a chibi styled Black Rock Shooter named Rock-chan and her babysitter De-chan.
Black Rock Shooter: The Game takes place in the year 2051, where Black Rock Shooter is awoken from slumber and enters a futuristic battlefield where alien forces have invaded the Earth and have been terrorizing the planet for 19 years. She must fight off the aliens, while also trying to regain her memories.
