Black Rock Shooter

In another world, the eponymous Black Rock Shooter battles a mysterious red-eyed opponent. Meanwhile, in the human world, Mato Kuroi enters middle school and takes an interest in her classmate, Yomi Takanashi. The two quickly become friends due to their common fondness for a book from their childhood. After inviting Mato to her house, Yomi becomes worried when Kagari Izuriha, a wheelchair-bound girl who wants to keep Yomi to herself, arrives and acts with hostility towards Mato, causing her to become frightened. Meanwhile, in the other world, Black Rock Shooter follows a green trail to a wasteland filled with broken toys where she is attacked by a girl resembling Kagari named Chariot.

As Black Rock Shooter continues to struggle against Chariot and Dead Master, Mato waits at the festival for Yomi, but she never arrives as Kagari wouldn't let her. As Mato dreams that night of Black Rock Shooter, who had a heart scarred on her chest, she discovers Yomi has the same scar the next day, yelling at her for having no spine. After consulting with Saya, who tells her dreams serve a deep meaning between friends, Mato goes to Yomi's house, but Kagari stops Yomi from coming to see her by throwing herself down the stairs. As Kagari is taking into hospital for a twisted wrist, Mato hears from Yomi's mother about how Kagari was hit by a car whilst chasing after Yomi, demanding she look after her. Determined in her belief that Yomi shouldn't suffer for that, Mato voices her pleas to go home with Yomi, calling her by her first name. Mato helps Yomi realise her true feelings, wanting to be earnest friends with both Mato and Kagari. As Dead Master manages to break free from her binds, but she is captured by another evil, Black Gold Saw, whilst Black Rock Shooter is forced to kill Chariot, which has its effect on Kagari.
