Black Rock Shooter (ブラック★ロックシューター)

plot
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.
The OVA focuses on Mato Kuroi (黒衣 マト Kuroi Mato?, Voiced by: Kana Hanazawa), who makes friends with a girl named Yomi Takanashi (小鳥遊 ヨミ Takanashi Yomi?, Voiced by: Miyuki Sawashiro) who recently moved to the town. Mato quickly joins the basketball club, which incites Yomi to join the volleyball club since both clubs practice at the same time in the gymnasium. The two spend much time together over the following year, and during one outing Mato gives Yomi the same cellphone charm she has. In their second year of junior high, they end up in different classes, reducing the amount of time they can spend together. Furthermore, Yomi starts to become jealous of Mato hanging around her basketball club manager and classmate, Yuu (ユウ?, Voiced by: Kana Asumi). When Yomi seemingly disappears, Mato becomes concerned when she does not show up at school the next day or respond to her text messages. Mato becomes further depressed when she receives word that Yomi has been reported missing and is asked about her whereabouts by two detectives. One day, Mato receives a blank text message from Yomi and goes to her favorite spot in town where she finds the phone charm she gave her. The charm starts to glow and transports her to a strange world where she meets a mysterious girl named Black Rock Shooter (ブラック★ロックシューター Burakku Rokku Shūtā?), who has a blazing blue left eye and a rock cannon which can fire 20 shots per second.[1] As Mato tries to find Yomi, she merges with Black Rock Shooter and duels Yomi, who was possessed by an evil being called Dead Master (デッドマスター Deddo Masutā?), who wields a large scythe.[2] As the possessed Yomi is about to fall to her death, Black Rock Shooter saves Yomi from falling, and embraces her, causing Yomi's body to be free from Dead Master. The events of their lengthy battle are dispersed throughout the anime. Yomi and Mato return to their normal lives, but Yuu begins to act strangely.
The manga series, Black Rock Shooter: Innocent Soul, follows Black Rock Shooter and her serpent partner, Ron, as they venture 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.
The video game, which takes place in the year 2051, Black Rock Shooter is awoken from slumber and enters a futuristic battlefield while trying to remember her past
